Application

Metal electrical switchgears and metal enclosures for electrical switchgears built to appliance class II standards are the latest products of our company. With the latest technical solutions, we have created a unique method of joining metal with insulation material. Appliance class II rating has been achieved with full double-sided (internal and external) coating of the aluminium or steel core of the enclosure with the insulation material: in a durable and permanent way, without coating with additional lacquers. The coat ensures maximum protection for a minimum of 30 years without loss of quality, along with high mechanical resistance to impact (IK 10). It is harmless for humans and the environment (confirmed with the environmental label), antiallergic, non-flammable (V0), very easy in cleaning (anti-graffiti and anti-poster surface finish), with low abrasion coefficient. It ensures full protection against weathering, ageing, UV (index 0), acidic rain, salt, corrosion and abrasion. Small damages to the coat may be repaired without replacement of the whole switchgear.

Equipment

Our technology of application of insulation material on metal plate allows its application on most of the enclosures produced by PRE Edward Biel. The switchgears are produced to appliance class II rating:

  • RST – Transformer Station Switchgears
  • ZK – Cable Boxes
  • ZPP, ZPP-P, ZZP – Metering units
  • SON – Street Lighting Cabinets
  • TLP – Metering and Distribution Boards
  • OU-2 – Metal enclosures and shielding doors for all types and dimensions.

The metal electrical switchgears built to appliance class II rating successfully replace switchgears in thermosetting plastic enclosures.

Design

  • indoor and outdoor use
  • free-standing on foundation, free-standing on a plinth, wall-recessed, wall-mounted, hanging on fixtures
  • made of aluminium or steel
  • varied insulation material coat and steel core thickness
  • insulation material available in many RAL colours (e.g. 7035, 7016, 7001, 6009, 6005, 7001, 5015, 5005, 9016, 6014, 7040, 7035, 3020, 3009)
  • robust structure with coat of high resistance to destruction and other external factors

The dimensions and type of the enclosure are custom designed for the Client or follow the current standards.
