1. Brief introduction TD 33KV 36kv 1600A 25KA (JUC632) vacuum interrupter for VCB The interrupter adoption porcelain and ceramics lagging makes to insulate the outer shell. Contact is CuCr metal alloy material advanced technique of cup construction, break the discharge big. Insulate the level high, breaking the abiliting strong, the life span is long, mainten anle is sample, no explosion dangerous, no contaminate and the noise is low. The load switch main used electric power, machine, coal mine, chemical engineering, petroleum metallurgy etc. power transmission system used control with protect. more than keeping with at the multifarious operation. Rated voltage: 33KV 36KV Rated current: 1600A Rated short-circuit breaking current: 25KA Rated short-circuit making current: 63KA Rated peak withstand current: 63KA Rated short-time withstand current: 25KA Rated short-circuit continuous time: 4 s Rated single capacitor unit breaking current: 630A Rated back to back capacitor unit breaking current: 400A Rated short-time (1 min) withstand voltage: 95 KV Rated contact pressure time-limit loop resistive: =25µO Rated short-circuit breaking current breaking times: 30 Ops Rated lightning impulse withstand voltage: 185 KV Mechanical life: 10,000 Ops Contact automatic: 200±50 N Force required to hold contacts open at full stroke: 300±50 N Contact-wear allowance thickness: 3 mm Internal gas pressure: =1.33×10-3 Pa Shelf life: 20 years
