Oil immersed type transformr
Product Description
VS1 indoor medium voltage Vacuum Circuit Breaker is a three-phase AC 50Hz ,rated voltage 6KV,12KV,24KV switch equipment of power system.
Breaker adopts the integral design of the actuating mechanism and the breaker body, which can be used as a fixed installation unit or as an individual VCB carriage together with handcart. They have a long life expectancy. There is no adverse effect on the vacuum, even from frequent switching of operating and short-circuit currents.
Advantages
- Highly reliable operating mechanisms thanks to a low number of components which are manufactured using production systems for large quantities
- Extremely limited and simple maintenance
- The electrical accessories can be installed or replaced easily and rapidly thanks to the cabling which is already prepared with its own plug-socket connectors
- Protective covering over the opening and closing pushbuttons to be operated using a special tool
- Superior breaking capacity: It can break the circuit quickly and reliably to ensure the safety of the power system.
- Long electrical life: The vacuum interrupter has a long electrical life, reduces maintenance frequency and cost, and improves the reliability of the product.
- Strong insulation performance: The product has a high insulation level, strong anti-interference ability, and good arc extinguishing performance.
- Wide application range: It is suitable for various fields and industries with different requirements.
- No emission of gas in atmosphere, little maintenance required, no danger of fire, silent operation
