Product Description

JLSGB Electronic type current and voltage combined mutual inductor made by Beijing Nobbel Electrical Tech Develop Co., Ltd. is used for high voltage electrical measuring and protecting, both for indoor and outdoor.

JLSGB Electronic type current and voltage combined mutual inductor is different from other similar current transformers at home and abroad. With reasonable design, novelty structureaesthetic configuration and silicon rubber outer insulation sleeve umbrella group, the mutual inductor has no oil, no ceramic, no gas, is convenient for operation and maintenance.

1. Advantages:

1. Dry-type insulation

2. No oilfilling, no gasfilling, no ceramic

3. Safety, easy operation, no maintenance

4. High ability of antipollution
