  展会风采：

Guangzhou Xigu Electric Equipment Co., LTD. (referred to as: Xigu Electric) is a professional  committed to the selective protection of mine leakage fault technology enterprises, the application of transient line selection principle, developed with the international leading level of MCC20 mine leakage protection device.

MC C20 series mine leakage protection device is mainly used in 380V, 660V,1140V, 10kV and  other neutral.Point ungrounded system. The device uses high frequency transient signal to realize leakage line selection and selective protection of low voltage system. It can adaptively capture high frequency (2k~3kHz)  transient signal of zero sequence current, and is not affected by stray interference on site. The line selection accuracy is above 95%, filling the gap of realizing the selectivity protection of low voltage leakage. The  problem that low voltage gold leakage can not be accurately selected and tripped is solved. At the same time, through the 4G network, the MCC2000 mine leakage fault management system is formed, which can truly solve the  problems of selectivity, quick movement, sensitivity and reliability of mine power grid leakage fault.

The MC C20 mine flameproof selective leakage protection device adds a protection to every  life and every asset under the mine.
