parameter

high voltage distribution cabinets refer to electrical products used for power generation, transmission, distribution, energy conversion, and consumption in the power system, with functions such as on/off, control, or protection, and voltage levels ranging from 3.6kv to 550kv. most power supply bureaus and substations use high-voltage switchgear, which is then led out from the low-voltage side of the transformer to the low-voltage distribution cabinet. the low-voltage distribution cabinet is then connected to various electrical equipment such as distribution boards, control boxes, and switch boxes to meet the design functional requirements of the distribution equipment.

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
