krc-gis-12/24 fully insulated, fully sealed, and common box type ring network switchgear (referred to as inflatable cabinet) is a new generation of miniaturized modular switchgear. it has the advantages of compact structure, fully enclosed, fully insulated, long service life, maintenance free, small space occupation, safety and reliability, and is not affected by the working environment.
suitable for small secondary distribution stations, switching stations, industrial and mining enterprises, airports, railways, commercial areas, high-rise buildings, highways, subways, tunnels and other fields.
product technical features:
1. adopting heat shrink insulation materials and epoxy coating insulation process, optimizing electrode shape, compact cabinet structure, and reducing floor area;
2. the switchgear cabinet body is made of high-quality cold-rolled steel, which is formed by cnc sheet metal processing and connected by high-strength bolts and nuts and rivet nuts. the surface of the components is sprayed with plastic or galvanized technology;
3. it can be matched with domestic zn85-40.5 vacuum circuit breakers and foreign sf1, sf2, and fp system sulfur hexafluoride circuit breakers to meet the needs of different users;
4. each functional compartment of the switchgear is sealed with metal plates and equipped with independent pressure release channels;
5. circuit breakers, grounding switches, and other operations can be carried out when the switchgear is closed, achieving door closing operation;
6. the structural adaptability of the switchgear is strong, with over 198 main wiring schemes that can meet the needs of different users;
7. there is a mechanical interlocking device between the handcart, circuit breaker, grounding switch, and rear cabinet door to prevent misoperation. the "five prevention" functions are complete, safe and reliable
