The integrated monitoring system for cable tunnel uses modern high-tech electronic technology, sensor technology, computer network technology, communication technology and embedded technology to collect and analyze the data of cable tunnel environment, equipment and facilities, remote Monitoring of cable tunnel equipment is realized, which has the functions of data communication, data query, parameter setting and management.

Sz-efi-1 in order to solve this problem, we have developed hh-3710 type earth fault fixed-point system, which is mainly used in 380v-10kv distribution network when single-phase earth occurs. At the same time, it can also measure single-phase load current by using hand-held detection and hand-held device. The product has the characteristics of light structure, simple operation, accurate positioning, convenient load current measurement, etc.
