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, and long working hours (ultra-low power consumption). It is widely used in various types of switch cabinets, high-voltage electrical contacts in substations, wall bushings, cable tower joints, etc. The introduction of temperature rise data on the basis of electrical contact temperature measurement is more intuitive and convenient for engineers and management personnel, bringing economic benefits to them and preventing accidents. High-definition large-screen LCD displays real-time data, user-programmable on site, event logs can be maintained for overheating alarm indications and power failures, one-hundred-year clock calendar, sound and light alarm output, integrated embedded installation, with RS485 communication interface, and MODBUS open and unseal protocol.
