You can rest assured to buy 33 35 kv 33kv vcb Vacuum Circuit Breaker from our factory. Conso Electrical Science and Technology Co., Ltd, has more than decades to produce 10kv to 35kv electrical equipment such as 35 kv vcb Vacuum Circuit Breaker and distribution transformer. Conso Elecrrical also is a manufacturer to produce 35kv compact substation. To make a qualified 35 kv Vacuum Circuit Breaker. The company picks the main components from large corporation. The company strict to execute the requirement of ISO9001 and ISO14001 to make a promise to clients to have a smooth user experience.
1. The circuit breaker adopts an integrated and modular design, featuring a simple and rational overall structure. It is arranged in an upper-lower configuration, with the arc-extinguishing chamber located on top and the interlocking and operating components below. Utilizing a dedicated spring-pneumatic operating mechanism, it requires no adjustment, ensuring stable and reliable operation.
2. The vacuum arc-extinguishing chambers for the three-phase conductive circuits of the circuit breaker are arranged within a sealed insulating cylinder. The insulating cylinder is constructed using materials with reliable electromechanical properties and a mature vacuum casting process. This not only significantly enhances the interphase insulation performance but also shields each phase circuit from adverse external conditions, preventing dust and foreign objects from entering the main conductive circuit and reducing the overall size of the circuit breaker.
3. The circuit breaker employs the latest domestically designed coil-type longitudinal strong magnetic field structure for the vacuum arc-extinguishing chamber. It features a ceramic casing and copper-chromium contact materials, offering a compact size, high insulation level, strong arc-extinguishing capability, long electrical life, and excellent performance in opening and closing under short-circuit currents.
