Product Introduction
VS1 indoor medium voltage Vacuum Circuit Breaker:
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.
Product Advantage
1.Reliable Structure
VS1 type VCB consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column made of epoxy resin by APG technology, therefore with high anti-creepage function. Such structure design greatly reduces the accumulation of dusts on the surface of vacuum arc- extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influences, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment.
1.with reliable interlock functions, suitable for frequent operation;
2.low noise and energy consumed;
3.simple and robust construction;
4.high operating reliability;
5.mechanical durability of switch : 20000 times, etc
2. High-Quality
1. Our factory has a unique comprehensive testing center, and each finished transformer needs to pass the test before it can be shipped;
2. After each process in the production of the transformer is completed, we will conduct a qualified test, and the quality of the transformer has reached the highest level.
