High Voltage Current Transformer (66kV, 72.5kV,58kV)

详情

The LGB High-voltage Dry-type Current Transformer made by Beijing Nobbel Electrical Tech Develop Co., Ltd. is used for high voltage electrical measure and protect, both for indoor and outdoor.   The LGB High-voltage Dry-type Current Transformer is different from other similar current transformers at home and abroad. With reasonable design, novelty structure, aesthetic configuration and silicon rubber outer insulation sleeve umbrella group, the current transformer has no oil, no ceramic, no gas.

1. Advantages: Dry-type insulation No oil filling, no gas filling, no ceramic Antipollution Easy operation and maintenance
