Overview
Vacuum Interrupter for vacuum circuit breaker (TD-40.5/2500-31.5)
Product Details
Volcano Electrical have developed and produced more than 100 types of 1.14kV-40.5kV vacuum interrupters and solid sealed poles for vacuum circuit breakers, contactors and load break switches , which are widely used in power, metallurgy, mining, petrochemical, railway, broadcasting, communication, industrial high-frequency heating and other power distribution systems, with complete product specifications and stable and reliable quality.
Equipped with advanced technical equipment and production line, the production of vacuum interrupter adopts advanced one-time sealing and discharging technology, coupled with the rapid leak detection technology of positive pressure equipment, effectively reducing the product leakage rate. The special current & voltage aging process, optimized design of vacuum tube, strict production process and quality control process ensure stable and reliable product quality and good consistency.
