The introduction of function:

        When there are lightning over-voltage or switching over-voltage in the system,the metal-oxide varistors have low resistance and the harmful over-voltage energy is discharged into earth, so that the over-voltage is limited to be lower than the allowable value, thereby reliably protect the electric equipment. When the system is under normal operation voltage, the metal-oxide varistors of the surge arrester have high resistance and the leakage current passing through the surge arrester is very small(Microampere level), so that the electric equipment is reliable in services.

The parameters of fuse

 Jiangsu Xinmin Electric Power Equipment Co.,Ltd, founded in 1997, is a Sino-foreign joint venture to make products on high&low voltage power system and to improve electric energy quality of power grid and energy-saving.

     Main products are:0.22KV~220KV series complex metal oxide surge arresters and porcelain oxide metal surge arresters,10KV series fuse protectors,10KV series outdoor single pole isolating switch, insulated protective enclosures, metal oxide varistor block,reactive compensation cabinets etc. The products are qualified in the inspection by State High-Voltage Electrical Apparatus Quality Supervision Inspection Center and  Electric Power Equipment Quality Inspection Test Center. The performance of the products conforms or exceeds national standard.
