2. CIVIL WORKS

2.1. GENERAL DESIGN

• Generally speaking, departmental substations shall be designed in accordance with typical drawings included in section 10. When local conditions are suitable (not frequently flooded area), basic solution (drawing 2) will be preferred. If the site is subject to flooding alternative solution (drawing 3) will be chosen. Then the stairs shall be completed with adequate handrails.

• The electrical equipment shall be installed preferably along the walls, keeping 100 to 200 mm space for ventilation.

• For each modular switchboard (MV switchboard, MCC, marshalling boards, …), spare room shall be kept for future installation of at least one additional module.

• In particularly, civil works design:

� shall include reservations for the installation of a technical floor covering the whole Electrical Room (access airlock excluded). A free space of 3000 mm minimum shall be kept between this technical floor and the beams supporting the ceiling or the insulated ceiling.

� shall include cable trenches and reservations of any kind for cable routings (including embedded conduits and cable galleries).

� shall include supply and installation of transformers supporting rails and of frames for retaining leaking oil.

� shall include supplies and services listed in sections 2.2 and 2.3.

� shall include reservations for the installation, by others, of air-conditioning and pressurisation equipment detailed in section 4.

• Electrical rooms of different departments shall be segregated by fire resisting walls / floors and by 2 hours fire resisting doors.

• To avoid dust ingress electrical rooms shall not be equipped with windows nor with glass doors (that could be broken).

• Each oil-immersed transformer shall be segregated from other oil-immersed transformers by a fire-resisting wall, or better be installed in a separate room.

• Shall also be installed in the transformer room(s) equipment dissipating huge heat quantities (braking resistors, ...) or which are too large and not dust critical (fixed capacitor power factor correction banks, ...).

2.2. FINISHING ASPECTS AND PAINTING The Supplier shall:

• Install a thermal insulation under the ceiling of the whole substation if this ceiling is just under a roof. In the electrical room this insulation shall be covered with panels made of a sound-absorbing material.



/22

Rev. B

Materials used shall be non flammable and shall be certified by the National Fire Protection Association ( NFPA ).

• Fill in any hole or space through which the dust could penetrate, in order to make the pressurisation system efficient.

• Paint all the substation internal walls with a semi-glossy paint of light shade.

• Paint the concrete slab of the transformers room and of the airlock with a glossy paint of similar shade specially designed for concrete surfaces.

2.3. DOORS

2.3.1. Common requirements

• Doors shall be made of steel painted according to specification STD.2.99.0.V.98 or of anodized aluminium. Their design and installation shall meet the principles developed in typical drawings of section 10.

• A common key (pass key) shall make people able to open any door of any substation on the site (Master Key system). Locks shall be of dust resisting type.

• Alternatively, mechanical locks can be replaced by electrical locks controlled by a common access badge. If this solution is chosen the Supplier shall also supply a workstation for controlling this access system and equipment necessary for making personal access badges.

2.3.2. Electrical rooms, staff access door

• Staff will access the electrical room (clean area) through an airlock in order to limit dust ingress. This airlock will be, if possible, oriented towards the main building for facilitating staff circulation.

• Both airlock doors will be of local standard size, but not less than 2.10 m high and 0.90 m broad. These doors shall open towards outside and shall be equipped with antipanic bars at inside. They shall be equipped with seals to prevent dust ingress and with automatic door closers.

• The outside door frame shall border the door on its 4 sides, including a bottom section that will keep between the ground and the door a free space of 30 mm minimum to avoid that small stones could block the door. This outside door shall be equipped with a lock.

• A mat or a grate shall be inserted into the airlock slab, in order to keep the electrical room clean.

2.3.3. Electrical rooms, door for emergency exit an d equipment bringing in

• Except in small electrical rooms, a second door shall be installed at the other end of this area to facilitate staff evacuation in case of hazard, and also for bringing in the equipment.



/22

Rev. B

B

• This door shall be identical to the inside door of the airlock here above mentioned but, in order to bring in the equipment easily, it shall be surrounded with metallic panels fixed by bolts or by locks. The passage shall be 2.80 m high and 1.20 m broad when panels are removed.

• This door shall not be equipped at outdoors side with any handle or lock entry so that entering in this area will be by the airlock only (but at indoors side with a panic bar). This door being a single barrier to dust ingress (the airlock is a double barrier), it shall be really dust tight. As it will be used in case of urgency only, thin silicon seals can be used, easy to be broken in case of emergency.

• The door frame shall border the door on its 4 sides, including a bottom section that will keep between the ground and the door a free space of 30 mm minimum to avoid that a small stone could block the door.

Note : For small electrical rooms, staff entry and equipment bringing in will be by the same

access; this single access will be an airlock with both doors surrounded with metallic panels as explained here above.

2.3.4. Transformer rooms, staff access and equipmen t bringing in doors

• The transformer rooms shall be equipped with staff access doors identical to these ones described here above. These doors shall be surrounded with metallic panels removable to bring in equipment.

• Dimensions of these panels will depend upon equipment dimensions but when panels are removed the passage shall not be less than 2.80 m high and 1.20 m broad.

• These doors shall be equipped with louvres for circulation of cooling air. Note : In principle, access to medium voltage and low voltage bushings of each transformer is

interlocked with the position of the MV cubicle earthing isolator and with the position of the LV circuit breaker. If such interlock does not exist, the transformer room shall be equipped with a door locked when the MV earthing isolator is not closed or the LV circuit breaker not open.

3. TECHNICAL FLOOR

• A technical floor shall cover all the electrical room.

• It shall be designed for an even load of 1500 daN/sqm (15 kN/sqm) and a local load of 300 daN/sqm (3 kN/sqm) on a 25 mm by 25 mm area.

• It shall be made of modular panels (600 mm x 600 mm). Each panel shall be made of:

� a high density clipboard panel, at least 30 mm thick;

� a high pressure laminated surface;

� a PVC edge, or better aluminium, crimped around panel sides.



/22

Rev. B

Panels shall be non flammable and shall be certified by the National Fire Protection Association (NFPA) or at least comply with ASTM standards.

• Panels shall be supported on a steel structure made of adjustable jacks and mobile supporting steel sections. Each steel item shall be protected from rust by hot dip galvanisation.

• Jacks shall be fixed to the base ground by bolts or glue. Their length shall be so that technical floor finish surface be at not less than 600 mm above supporting concrete slab. When necessary, additional steel sections shall be installed for reinforcing panels placed in cantilever, in order to keep resistance to here above mentioned loads. Technical floor installation is explained in section 10, drawing 5.

• A suction disc for lifting technical floor panels shall also be supplied in each electrical room as specified in section 6.4.

Note : For a revamping, if it is not possible to install a technical floor, the electrical room’s

ground shall be covered with a plastic material (tiles or bands) limiting dust emissions and reducing electrical shock hazards by insulating operators from the ground, or at least with insulating mats on front and back of each cabinet.

4. AIR-CONDITIONING AND PRESSURISATION

4.1. AIR-CONDITIONING

• Air-conditioning system for the electrical rooms shall be reliable and simple. Priority shall be given to reliability rather than to performance.

• In countries with a hot climate (when average day/night temperature exceeds 35°C during more than 7 days a year) double air-conditioners shall be used, one unit only being able to keep internal temperature under here after mentioned maximum temperature.

• Air-conditioning units will use water cooled condensers or be of the "split system" type with an air cooled condenser installed outdoors.

• Electrical equipment shall be protected IP55.

• Air-conditioning system shall be dimensioned to keep into the Electrical Room a temperature lower than or equal to 28°C . This requirement is for limiting the temperature inside the cabinets so that this average temperature over a period of 24 h does not exceed +35°C as required by standard IEC 60947-1. The air-conditioning power installed shall not be less than 100 W/m3 of room volume; it shall be sufficient to evacuate:

� the heat dissipated in the room,

� the heat flowing through the walls, ceiling, floor of the room,

� the heat of the air injected in the room by the pressurisation system.



/22

Rev. B

B

• If batteries of lead-acid type are installed in the electrical room the ambient temperature of this room shall be limited to 20°C . Indeed, a temperature of 28°C would reduce consid erably its lifetime: raising the temperature from 20°C to 30°C divides by 2 the lifetime of a lead-acid battery. An alternative solution could be to install the battery in a separate room kept at 20°C maximum as it is common in incoming substations for feeding the HV switchgear control circuits.

• A heating system shall also be installed, if necessary, to keep the temperature above 15°C.

• Cool air shall be distributed from upside. Back air shall flow under the technical floor, passing through this floor by louvres to be installed at the opposite corner of the room to the air-conditioning unit. The Supplier will decide whether air distribution ducts should be installed for cool air.

• Please also refer to section 10, drawing 6.

4.2. PRESSURISATION

• Pressurisation of the electrical rooms is to avoid or limit dust ingress. This system shall be capable of keeping into the room a 20 mm water column (200 Pa) overpressure with a minimum air flow equal to 2 times the room volume each hour. This capability will be demonstrated by submitting to the Owner’s approval appropriate technical data (fan curve) about proposed equipment.

• Pressurisation equipment shall be mounted through the wall with an access for maintenance from the outside. It shall include:

� a static filter with an easy access for maintenance, generously dimensioned to avoid maintenance intervals shorter than three months. This filter shall stop any sedimentable dust particle (size above 10µm) and be of class EU4 (90 % weight efficiency). Self cleaning filters shall be proposed by the Supplier as an option;

� a low noise fan running at 1500 RPM at the maximum with a motor protected IP55;

� a fresh air inlet duct in the electrical room.

• The pressurisation system shall automatically be switched off in case of fire (please refer to section 5.2).

• Please also refer to section 10, drawing 7.

4.3. POWER SUPPLY Air-conditioning and pressurisation systems shall be fed from a single feeder from a lighting distribution board ; please refer to specification STD.002.U18 : “Lighting and Power Outlets”. The electrical cabinet protecting and controlling power supply to air conditioning and pressurisation equipment is included in this Supply.

5. LIGHTING AND FIRE DETECTION

5.1. LIGHTING

• Technical specification: substation lighting shall meet the clauses of specification STD.002.U18.

• Electrical Rooms shall be illuminated with fluorescent lamps (except for very high ceiling substations where it will be better to use high pressure sodium lamps). All these lighting fittings shall be controlled by a switch installed in the area access airlock. Emergency lighting blocks shall be installed inside this area above each access door and in the airlock. In large rooms, some additional emergency lighting blocks shall also be installed throughout the room to facilitate the exit.

• Transformer Rooms shall be illuminated with watertight fluorescent lamp fittings. These lighting fittings shall be controlled by switches installed close to each access door.

• Power outlets: at least two single-phase power outlets shall be installed in each electrical room and one in each transformer room.

5.2. FIRE DETECTION

• Automatic fire detectors: ionisation fire detectors shall be installed:

� in the electrical rooms above technical floor;

� in the electrical rooms under technical floor, protected by a wiremesh cover;

� in the transformer rooms above transformers.

The numbers of detectors shall be adapted to volumes to be monitored.

• Non automatic fire detectors: 1 push button protected by a breaking glass (IP65) shall be installed close to the access doors to the transformer rooms.

• Annunciators: 1 red lamp flashing lamp (IP 65) and 1 amovible signal, 100dB at 1m

• Monitoring: all the detectors of each substation shall be connected to a common monitoring panel installed in the Central Control Room. Each substation will be a separate monitoring area on this panel.

• Integration in an existing fire detection system: if the plant is already equipped with a general fire detection system the present supply shall be integrated into the existing system and fires annunciated on the existing general fire monitoring panel in the CCR.

• The fire detection system shall automatically switch off the pressurisation fan in case of fire (please refer to section 4.2).
