a、采用熱縮絕緣材料及環氧涂覆的絕緣手段，優化電極形狀，柜體結構緊湊，占地面積
小；
b、可配用3AV3(ZN85-40.5)真空斷路器和施耐德SF1、SF2型及阿爾斯通FP系列六氟化硫
斷路器，以滿足不同用戶的要求；
c、開關柜各功能小室均采用金屬板封隔，并設有獨立的壓力釋放通道；
d、斷路器、接地開關等操作均可在開關柜門關閉的情況下進行，即可實現關門操作；
e、手車、斷路器，接地開關和后柜門之間設有防止誤操作的機械連鎖裝置，“五防”功
能齊全，安全可靠；
a、Different insulating means are applied such as using thermal shrink insulating materials and epoxy
covering for the purpose of electrode shaping optimization which results in compactness of the cabinet
so as to reduce the occupied land area;
b、The Cabinet may be equipped with domestic ZN85-40.5 (3AV3) vacuum circuit breaker (VCB),
Schneider SF1 and SF2 VCBs, and Alston FP Series of SF Circuit Breakers just for customers’ option;
