Vacuum interrupter 400A core component of medium and high voltage power switches for vacuum contactor
The arc extinguishing chamber uses porcelain and ceramics to insulate the shell. The contacts are made of metal alloy material, using advanced technology and small size. It has a strong crushing capacity, long life, simple maintenance, no explosion hazard, no pollution, and low noise. It is widely used in coal mines, the chemical industry, petroleum metallurgy, and other departments, and is suitable for use in various operations and places with harsh environments.
Features
- Long life: High-quality materials and precision design give it excellent durability and stable operation for a long time.
- Low maintenance costs: No routine maintenance is required, reducing operating costs.
- Reliable operation: The vacuum arc extinguishing chamber can quickly extinguish the arc and suppress the current to avoid accidents and accidents.
- No pollution: Because it is in a vacuum state, there is no pollution problem and it is environmentally friendly
Applications
- Vacuum interrupters are widely used in power transmission and distribution control systems, metallurgy, mining, petroleum, chemical industry, railways, broadcasting, communications, industrial high-frequency heating and other power distribution systems
