2. Product Overview

Cable Sheath Circulating Current Online Monitoring System

With the rapid growth in power demand, the operational management standards for high-voltage power cables have become increasingly stringent. Among the various aspects of cable maintenance, controlling the circulating current in the cable sheath is particularly critical. Once an abnormality occurs in the circulating current, it is often accompanied by problems such as high-temperature heating, which not only accelerates the aging of the insulation layer but also significantly shortens the service life of the cable. To address this challenge and ensure the stability and safety of power supply, Shenzhen Telincon Technology Co., Ltd. has meticulously developed the TLKS-PLGD Cable Sheath Circulating Current Online Monitoring System. This device can realistically and accurately reflect the actual operating status of cable equipment and provide timely early warnings for abnormal circulating current, helping operation and maintenance personnel identify potential issues in advance, reduce the likelihood of accidents, and minimize the resulting losses.
