1 Overview

Using today's most advanced microelectronics technology, radio technology and microcomputer technology, the high-tech products developed by our company have successfully and reliably solved the problem of high-voltage electrical contact safety for many years. This product has the advantages of real-time, reliability, safety, long working hours, and ultra-low power consumption. It is widely used in various types of switch cabinets, high-voltage electrical contacts in substations, wall bushings, and cable lap joints. The temperature rise data is introduced on the basis of the temperature measurement of the electrical contact, and at the same time, it can measure the full power parameters, which can directly replace the power meter and the electric energy meter. It greatly facilitates engineering personnel and management personnel, brings economic benefits to them, and prevents safety accidents. This equipment is a top-level product in electrical temperature measurement products.
