Product Overview
GRM6-40.5 Series yog hom tshiab SF6 gas-insulated compact switchgears. Circuit Court breakers, disconnectors, thiab lwm yam yog nyob rau hauv 3 hli-thick hlau thawv ntim nrog ib tug tsawg-pressure SF6 roj. Yog li, cov khoom siv yog compact, txhim khu kev qha, thiab nyab xeeb; tsis muaj kev cuam tshuam ib puag ncig, kev saib xyuas dawb thiab kev pab lub neej ntev, thiab lwm yam.
GRM6-40.5 Series switchgears yog tsim rau kev tswj, kev tiv thaiv thiab kev saib xyuas ntawm 40.5 kV, peb-theem, ib tug busbar hluav taws xob system, lug siv nyob rau hauv generating tuam txhab uas muag, mining, thiab lwm yam.
