Tested in accordance with IEC 62271-202 standardThe MV/LV prefabricated substations being installed in accessible places, you are looking for solutions that guarantee a high level of security for your operators and the public.

Biosco offer answers your needs for safe substations, throughout their life cycle. Biosco substations have been designed, manufactured and tested according to IEC 62271-202 standard, which defines the technical characteristics, rules for conception and construction but also the type-testing methods to guarantee safety for all.Our technical and industrial know-how enables us to guarantee the same quality level for each substation.

safety of people - Mechanical tests to guarantee substation

resistance in case of overloads on the roof and mechanical impacts.

- Degree of protection tests to guarantee protection against direct contacts.

- Internal arc tests to guarantee absence of small parts projection or flames outside of the substation in case of fault inside the MV switchgear.

safety of operators

- Internal arc tests to guarantee absence of small parts projection or flames in front of the MV switchboard.

- Earthing verification tests to guarantee the ability to withstand short-circuit currents.

operating safety

- Dielectric tests to check the insulation level of the MV and LV interconnections.

- Temperature rise tests to determine the enclosure class.- Degree of protection tests to guarantee the protection

of equipment against ingress of water and dust.- Functional tests to check that the operation is overall

satisfactory.

Quality and environmental certifications.

environmental safety

- Sound level tests.- Retention of potentially hazardous liquids.- Design of the substations with EIME

software (Environmental Information & Management Explorer). ISO 9001

and 14001

Schneider Electric has its own laboratory approved by ASEFA.

Suited to you needs You are looking for solutions of MV/LV prefabricated substations in compliance with IEC 62271-202 and that meet your local environmental regulations.

The MV/LV prefabricated substations have been designed to meet local standards.The adaptations you need are studied by our teams of specialists, and are implemented with dedicated conception and simulation tools.For each study of adaptation, the compliance of the substation with IEC 62271-202 standard is validated by calculation, simulation or by type-testing in laboratory.

Adaptable to weather conditionsIn view of the most harsh environments (temperature, sand, dust...), we validate the best solution between natural ventilation system, degree of protection and compartmentalisation of the substation.We define the switchgear to use and their possible decommissioning.To prevent from water floods, we use switchgear with genuine total insulation and offer elevated installation solutions.When the substation has to face cold spells and snowfalls, we implement heating devices against condensation, tightness against frost and thaw and adapt the mechanical endurance of the enclosure.

Adaptable to standards, regulations (town-planning, transportation...) and aestheticsWe make sizing of the substation evolve to satisfy currently applicable regulations for allowed heights and surfaces, and optimise weight.To comply with town-planning requirements, limit visual impacts and improve integration into the environment, we help you define the type of substation and put at your disposal a wide choice of options for cladding, colours and roofs.

Adaptable to technical characteristicsWe integrate local transformers by adapting the substation sizing, ventilation systems and determine the enclosure class.

Easy to operateand equipped to improveyour efficiencyYou are constantly looking for reliable and innovative solutions to manage your network in any event and improve your SAIFI and SAIDI indicators.

For over 30 years, Biosco MV/LV substations have integrated the best Schneider Electric components, providing a simple, safe and efficient operation in consistency with your costs optimisation and quality of service policies.

@ You reconfigure your MV network either manually or remotely thanks to the control unit which also integrates fault detection.

@ You optimise the operation of your MV network by analysing the data brought by a power, current and voltage measurement unit.

@ In case of transformer change, you ensure continuity of service by reenergising the LV network thanks to a generator.

@ You reduce maintenance operations by using MV cubicles with SF6 breaking technology.

@ You optimise use of the transformer by controlling overheatings thanks to the Biosco guaranteed temperature class: life span increase and use of maximum power.

@ You improve the efficiency of your network by reducing losses of reactive energy by using capacitor batteries.

Biosco: the all-in-one solution.

The Biosco substations help you improve your SAIDI and SAIFI indicators (System Average Interuption Duration Index and Sytem Average Interuption Frequency Index).
