Intro：Puncture current transformer is installed online without power failure, with built-in current transformer, electric needle, temperature sensor, and a diversified design concept. It is easy to install. It is mainly used in power transformation and installation projects. All places where people operate are insulators, making installation safe, convenient, and simple. When installing the puncture type current transformer, the measured line passes through the middle hole, passes through the transformer, and outputs a current signal, which is converted into the required voltage signal through the sampling resistance, and is output as a lead wire.

Intro：The insulation puncture clamp mainly consists of a reinforced housing, stainless steel puncture needle, sealing pad, waterproof silicone grease, knob stainless steel bolt, and locking pressure plate knob. When the cable needs to be powered on, clamp the puncture plate into the cable branch line. After determining the main line branch position, rotate the fixed pressure plate. After the pressure plate is locked, rotate the puncture knob to contact the conductor, and the sealing pad presses around the punctured position of the cable, When the puncture needle pierces the cable and contacts the copper wire, a temperature sensor can be built in, and performance parameters can be customized.
