Secondary substation 315-1250 kVA
Product quality
With its many qualities, sheet steel is the obvious choice of construction material. Steel is cost effective, strong and pliable. It is an excellent material for building safe and robust secondary substations. When handled right, a sheet steel secondary substation provides more service life than required.
Personal safety
Our secondary substations are constructed with the highest priority for personal safety with plenty of space and well proven and back-mounted technology to ensure work with voltage is carried out in a secure manner. The stations have been tested according to IEC62271-202 type A and B to ensure electrical arc safety.
Flexibility
There are many possibilities for customisation, as well as a wide portfolio of standard solutions. There are essentially no restrictions when constructing a station to meet individual requirements.
Medium-voltage
Alternative solutions for 12-36 kV
Transformer
Standard up to 1250 kVA or customised
Station Materials
Aluminium-zinc or Magnelis on sheet steel or concrete foundations to withstand tough environments
Customisable
Solutions customised to requirements
Smart secondary substation
Future-proof options for metering, automation and information
Plug and play
Industrially built in the factory, including testing of live operational environment before delivery
Air insulated medium-voltage 12–24 kV
- Equipped with NAL/NALF apparatus, with maintenance interval 15 years.
- Arc fault tested according to substation standard IEC 62271-202 type A and B.
- NAL/NALF apparatus is always installed on the back of the compartment. This provides you the customer with: – plenty of space to work in the station when e.g. connecting your medium voltage cables – the possibility of employing live working methods, simply.
- Outer and inner roof sprayed with anti-condensation compound to prevent droplets falling on electrical equipment.
- Earth distance always between apparatus and cabinet, for example at the shield plate guides.
- Can be delivered with a pre-mounted transformer.
RMU switchgear 12–36 kV
-
Equipped with RMU switchgear selected by the customer.
-
The transformer stations fulfil arc fault requirements according to substation standard IEC 62271-202 type A and B. When RMU switchgear requires pressure relief, this takes place through channels in the transformer compartment.
-
Can be delivered with a pre-mounted transformer. The size depends on the station type.
RMU Magnefix switchgear 12 kV
- Equipped with fully-insulated epoxy-resin insulated medium voltage switchgear type Magnefix.
- The enclosure is equipped with:
– floor membrane to prevent ground moisture intrusion,
– sealing strips in the doorway and ceiling to prevent the intrusion of dust and dirt,
– anti-condensation compound on the roof interior and ceiling to prevent condensation and the formation of droplets.
- The transformer station for RMU Magnefix switchgear has a 20-year maintenance-free guarantee.
- Can be delivered with a pre-mounted transformer.
Customisation
Facade finishes
For the cladding, there are three types of metal sheet panels to choose from. Standard panels, thin panels and lath panels. The standard colours are red, green and grey. Optional NCS colours are available as extras.
Roof
There are also different roof designs, for example a pitched roof with a 20- or 30-degree pitch, a hip roof or a round roof.
IT equipment
Stations can be provided with a separate area for IT equipment for better accessibility.
