1. The structure of the switch device is shown in Figure 1.
2. Fully metal assembled, modular structure with a wide range of combination options.
3. The cabinet is made of imported aluminum-zinc coated thin steel plate, processed by CNC machine tools, using advanced multiple folding technology, connected with pull lily nuts and high-strength bolts, with high precision, corrosion resistance, light weight, high strength, and strong component interchangeability.
4. Can be equipped with ZN 63A-12 series or imported VD4 series vacuum circuit breakers, with wide applicability, high reliability, and maintenance-free operation for many years.
5. The handcart device has positioning and display devices for working, testing, and various positions, ensuring safety and reliability.
6. Various types of handcart devices can be changed like modular blocks, ensuring free interchangeability among carts of the same specifications, while carts of different specifications are strictly prohibited from entering.
7. The handcart is transported by a dedicated carrier, making it easy and flexible to operate.
8. The cable compartment can accommodate up to 9 single-core cables.
9. Highly reliable interlocking device that fully meets the "five prevention" requirements.
10. Each high-voltage compartment has a pressure relief channel to ensure personal safety.
11. The front door is equipped with an observation window made of explosion-proof glass, allowing the working status of internal components to be observed.
12. When used under normal environmental conditions exceeding the GB3906 specifications, it should be determined through consultation between the user and the manufacturer.
