Product name:

i-AZ1A series gas-insulated metal-enclosed switchgear

Product introduction:

This series of products has a rated current of 1250~2500A, a double-filled compartment structure, and a side-parallel busbar expansion between the cabinets. It is a high-performance, high-quality gas-insulated product equipment with low-pressure SF6 gas insulation, miniaturization, intelligence, maintenance-free, full-condition, etc., which can adapt to various harsh operating environments. The inflatable compartment is welded with stainless steel plates, and the cabinet body is an aluminum-zinc plate assembly structure. The protection level of the inflatable compartment reaches IP65, and the annual leakage rate of the product is ≤0.1%. The upper inflatable compartment consists of a horizontally arranged direct-acting three-position disconnector and a main busbar; the lower inflatable compartment consists of a horizontally arranged solid-sealed pole vacuum circuit breaker and an inner cone.

Product features:

1. With low-pressure SF6 gas as the insulating medium, the insulation condition of the main circuit is not affected by the ambient conditions of the equipment operation site, and can adapt to various harsh operating environments;

2. Small size, saving equipment space;

3. Double gas-filled compartment structure, making operation more reliable;

4. The side panels of the gas-filled compartment are made of thin stainless steel plates, and the reinforcing ribs are made of new stainless steel rectangular steel pipes, which are low in cost, high in strength and small in deformation;

5. EVH3 series vacuum circuit breakers with integral spring mechanism;

6. Modular direct-acting GDS1 series three-position disconnectors;

7. With reliable mechanical interlocking, it can effectively prevent misoperation;

8. Equipped with side busbar connectors, no gas pumping and filling operations are required for on-site cabinet connection.
