Types of 35KV Vacuum Circuit Breaker
Superior Sealing & Vacuum Holding Performance
Our 35KV vacuum circuit breaker is built with precision sealing and multi-layer structural design for its vacuum interrupter.It locks in high vacuum permanently and never lets internal vacuum leak out.Custom engineered for 35KV high voltage use, it keeps reliable arc extinguishing and insulation performance even after years of continuous operation.You get far fewer hidden safety hazards from vacuum decay, and your high-voltage power grid can run stably and safely for the long term.
Strong Electromagnetic Interference Resistance
We equip our 35KV vacuum circuit breaker with dedicated anti-interference structure and premium shielding components.It works perfectly in busy high-voltage substations and industrial zones with heavy electromagnetic radiation.It shields your equipment from outside signal disturbance, preventing accidental switch closing, unwanted tripping and data malfunctions.It always stays accurate in operation, and delivers dependable power safety for your industrial facilities, substations and renewable energy projects.
The main reasons are loose wiring bolts, worn and oxidized contact surfaces, no conductive grease applied, and the contact travel becoming too short due to wear and tear. You need to take the unit out of service first, clean the contact surfaces, add conductive grease, tighten the bolts to the required tightness, and then test the loop resistance again.
This usually happens because the limit switch contacts are oxidized, the switch is out of position, or the gears get stuck. You can adjust and correct the limit switch, clean its contacts, check if the gears are properly lubricated, and replace the switch or spring if they are damaged.
Follow this order to find and fix the problem: dust or moisture on the insulating bushings and insulators, condensation inside the cabinet, reduced vacuum in the arc-extinguishing chamber, or damaged insulation in the secondary circuit. Clean and dry all the components, and replace any broken insulating parts and the arc-extinguishing chamber if needed.
