Discharge gap of SDFJ-1.5 overhead contact system

Product introduction：
Discharge gap of SDFJ-1.5 overhead contact system is applicable to lightning protection of lines of overhead contact system in 1.5kV DC power supply system. Post insulator is a composite post insulator, with high insulation performance, light weight, and easy installation mode. The gap is made of stainless steel spherical gap electrode, and featured by low discharge voltage dispersity, strong arc extinguishing capability, high impulse current withstand capability, and reliable performance. It has been widely used in the rail transit systems of major cities like Chengdu, Chongqing, Shenyang, Dalian and Dongguan.
