General descrIPtIon


TPR6 Plus is a maintenance-free, factory-assembled and type-tested medium-voltage switchgear. It is three-pole metal-enclosed and SF6-insulated. Vacuum circuit-breaker, switch-disconnector and disconnector modules are available. The core of the switchgear consists of hermetically welded containers made of corrosion-resistant stainless steel, accommodating the primary devices (circuit-breaker and three-position switch). The switchgear is sealed for life. The switchgear modules are interconnected by solid-insulated busbars outside the gas compartments.Gas work is not required, neither for installation at site nor for extension of the switchgear.The operating mechanisms of the vacuum circuit-breaker, three-position switch-disconnector and three-position disconnector are located outside the gas compartment and are therefore accessible at any time.Current and voltage transformers are usually located outside the gas compartment.Cables are connected from the front. They are arranged at one level side-by-side and at a user-friendly mounting height.

The internal enclosure of components, the internal arc resistant design and the complete interlocking concept all guarantee a maximum degree of personnel safety.

TPR6 HP PLUS is maintenance-free for life due to the following features:• No repair and maintenance cycles required.• Hermetically welded stainless-steel enclosure, with maintenance-free vacuum switching

technology and maintenance-free three-position switches.• Maintenance-free operating mechanisms for circuit-breakers and three-position switches.• Consistent implementation of full switchgear insulation down to the module connection by

means of cable plug-in systems.• No need to check the gas quantity and quality due to the welded stainless-steel enclosures.

The robust design of the metal enclosure prevents deformations and ensures protection against fault. TPR6 is designed to withstand an internal arc caused by a rated short-circuit current up to 31,5kA for 1s preventing every danger to the operator.

TPR6 is a completely “sealed for life” system with a stainless steel tank containing all live parts and switching devices. The structure can withstand the electrodynamics stresses during the operation. The operating mechanism, movable mimic and voltage signaling lamps are positioned in the front panel. Switches are operated by means of spring-operated mechanisms. Movable mimic gives the position of the switch whereas the voltage signaling lamp indicates the voltages. Fuses and cable compartment are easily accessible through the front door which is interlocked with the earth switch. If present, the low voltage auxiliary compartment is situated above the ring main unit.

General descrIPtIon


The cable connection compartment is only accessible from the front using tools. The three phases are arranged side-by-side at the same height. The connection height is higher them 645 mm in circuit-breaker and disconnector modules.In the different module versions it is possible to connect up to three cables per phase with shock-proof T-plugs according to the outside-cone system (DIN EN 50181, interface type C ). Symmetrical current distribution must be ensured.Using suitable T-plugs, with special test rod; cable testing can be performed directly at the cable termination.

The busbars are located outside the SF6 compartment in a metal enclosure. They are plugged onto the switchgear tanks from above and screwed tight. The busbar itself is made of round-bar copper, the length of which depends on the module width. It is insulated with silicone rubber, which is coated with a conductive layer on the outside and earthed. The bolted joints are insulated with cross adapters, also made of silicone rubber. These cross adapters are coated with a conductive layer both inside and outside. Therefore, no field distortion can appear at the high voltage joints. Due to the earthed coating of the busbar system, the arrangement is independent of environmental influences such as condensation and pollution.

Low voltage compartments are located at the front. The secondary devices (associated protection, measuring and control devices) are mounted in the low voltage compartment on a rear mounting plate or a DIN-rail system. Single devices can be integrated in the door of the low voltage compartment.General bus wires are laid in a separate connection duct located at the top.Customer-specific control cables can be routed to the low voltage compartment by means of a lateral duct to be fitted externally to the switchboard at customer care. External control cables are inserted on top of each respective low voltage cubicle.

Consistent hermetically welded enclosure of all live parts from the busbar down to the cable excludes any external influence on the primary part. In addition, the welded stainless-steel enclosures ensure that the loss of SF6 gas is impossible. Time-tested components such as bushings, welded-in bellows and the vacuum switching technology are integrated in this innovative global concept.

Hermetically welded stainless-steel enclosures make TPR6 PLUS insensitive to any environmental influences. The primary part is therefore consistently protected against external influences such as humidity, pollution, dust, aggressive gas, small animals, etc.Any pollution effect depending on humidity through seals is excluded by this design.The above mentioned reasons make the switchgear also suitable for application in extreme climates or under aggressive environmental conditions.Furthermore, the dielectric strength of this technology switchboard is independent of the altitude site.
