高压局放屏蔽室

适用范围 SCOPE OF APPLICATION

广泛应用于电力电缆、变压器、互感器开关、变电站等各种电压等级的局部放电试验或冲击试验。

It is widely used in partial discharge test or impulse test of power cable,transformer,transformer switch and substation.

分类 CLASSIFICATION 

· 拼装式 — — 采用优质镀锌钢板冲微孔加工成模框，中间夹导电衬，用螺栓固定拼接。

· 波浪板 — — 采用镀铝锌板冲孔后压制成波浪板，直接搭接用螺钉固 定在檩条上。

·Assembly type--high quality galvanized steel plate is used to punch micro holes into the mold frame,and the conductive lining is sandwiched in the middle,which is fixed and spliced with bolts.

·Corrugated plate--the corrugated plate is formed by punching and pressing the aluminum zinc plate,which is directly overlapped and fixed on the purling with screws.
