Product Information


Product introduction of VK12-12P(G) solid-sealed pole type indoor medium voltage vacuum circuit breaker  
VK12-12P(G) solid-sealed pole type indoor medium voltage vacuum circuit breaker is a solid-sealed pole-type circuit breaker specially designed by our company to invite domestic and foreign experts to specialize in design, with unique technology and obtain a proprietary model certificate. . The main design concept is: the main circuit uses solid-sealed poles to improve the environmental adaptability and insulation reliability of the circuit breaker, improve the mechanism design, extend the mechanical life and improve the mechanical reliability. Reliable mechanical and electrical performance, extending mechanical and electrical life, making maintenance-free circuit breakers possible.
The VK12-12P(G) circuit breaker is an indoor switchgear component with a rated voltage of 12KV and AC 50Hz. It is suitable for use in areas up to 4500 meters above sea level. The products meet the relevant domestic and international standards such as GB, DL, IEC, etc., and the performance reaches the level of M2-E2-C2.
The VK12-12(G) circuit breaker is equipped with a special propulsion mechanism to form a handcart unit. The circuit breaker is equipped with a reliable interlocking unit to meet the user's “five-proof” protection function.
Product information of VK12-12P(G) solid-sealed pole type indoor medium voltage vacuum circuit breaker
1. Meet the requirements for use in areas with an altitude of 4,500m or less 
Increase the air clearance to the ground, using high insulation performance of the arc extinguishing chamber to meet the requirements of high altitude areas.
2, the main circuit uses a solid-sealed pole
 The main circuit of the circuit breaker adopts APG process forming technology. The high-performance epoxy resin is used to seal the vacuum interrupter and the upper and lower outlets together, so that the vacuum interrupter is protected from dust, moisture and pollution, and the environmental adaptability is improved. And insulation reliability.
3. The circuit breaker is an M2 circuit breaker
 Superior mechanical performance, can be used in frequent operation, circuit breakers meet the requirements of M2 circuit breakers, mechanical life up to 20,000.
4. The circuit breaker is an E2 circuit breaker
The circuit breaker passed all type tests at the Shanghai High Voltage Apparatus Testing Center to meet the requirements of the E2 class circuit breaker. The circuit breaker broke the full capacity short circuit current for 30 times.
5, the circuit breaker is a C2 circuit breaker
During the breaking current of the circuit breaker, it has a very low probability of heavy breakdown and meets the requirements of the C2 class circuit breaker.
6, the circuit breaker mechanism has excellent corrosion resistance
   The mechanism parts adopt advanced surface treatment technology to make the parts more resistant to corrosion and higher mechanical stability.
7, using buffers with excellent buffer performance
 The specially designed buffer reduces the overshoot and tripping of the circuit breaker and improves the mechanical life of the circuit breaker.
8. Insulation rod with BMC material
The insulating material of the insulating rod is BMC, which not only meets the requirements of mechanical strength, but also has a large creepage distance along the surface, which improves the insulation performance of the circuit breaker.
9, the circuit breaker can be used at low temperature -25 ° C
  The circuit breaker uses special low temperature grease and a buffer that can operate at low temperatures, allowing the circuit breaker to be used at low temperatures of -25 °C.
