Application
For all switchgear requiring very high strength insulating material, providing full isolation and safety. The enclosure is applicable to the manufacture of switchgear:
- RST – Transformer Station Switchgear,
- SKS – HV Station Cable Cabinets,
- SWS – WN Station Interior Cabinets,
- ZK – Cable Connectors,
- ZPP, ZPP-P, ZZP – Measurement sets,
- SON – Street lighting cabinets,
- TLP – Floor board switchboards,
- RM – Modular Switchgear,
- OU – Metal enclosures (OU-IP, OU-W, OU-RM, OU-SKS, OU-SIT, OU-S),
- DU – Cover Doors.
Structure description
- Outdoor standing on a concrete or metal foundation;
- Internal standing on a metal pedestal or cable pocket;
- Surface and recessed (plug-in) designs are possible, mounted on a special structure;
- Made of aluminum or steel sheet joined by welding and bolting;
- The thickness of the sheet metal adapted to the dimensions of the housing;
- Can be achieved by an insulating layer, permanently lined on the inner and outer surfaces of the housing. The thickness of the layer ensures the right degree of insulation;
- Insulation coating with high resistance to deterioration and external factors;
- High resistance to UV, aging, weathering and aggressive chemical agents;
- Long-term durability of the insulation coating;
- IP30 to IP54 degree of protection;
- Mechanical resistance: up to IK10;
- Connecting to the foundation with insulation screws, and a special insulation spacer;
- Isolated attachment of all mounting components from the housing body;
- High mechanical strength at low and high temperatures;
- The anti-allergenicity and harmlessness of the materials used in the production and insulation of the housing;
- Easy to clean and remove dirt, anti-stain and anti-graffiti surface;
- Doors of solid design;
- Open to any side horizontally in single or double leaf versions;
- Lockable with a basquil lock with a system cylinder and an additional padlock;
- Additional gaskets installed in the door connection space provide additional tightness;
- Three-point locking;
- Adaptability of solutions to the applied apparatus, with the possibility of dividing into any number of parts – such as cable and measurement;
- Separate enclosures for individual modules;
- Single or gable roof with ventilation maze and double ventilation;
- Preventing the accumulation of water and moisture;
- The bottom has an opening to allow cables to enter from the cable duct.
