    • [ Industry News ] How to find if a cable fails

      How to find if the cable is broken 1. Sound measurement method: The so-called sound measurement method is based on the sound of the discharge of the faulty cable. This method is more effective for the high-voltage cable core wire to the insulation flashover discharge. The equipment used in this method is a DC withstand voltage tester. At the fault location, the cable core wire discharges to the insulation layer to generate a "noise, noble" spark discharge sound.

    • [ Company News ] Do you know the cause and solution of overheating of wires and cables?

      Do you know the cause and solution of overheating of wires and cables? 1. The resistance of the cable conductor does not meet the requirements, causing the cable to generate heat during operation. 2. The improper selection of the cable causes the conductor cross-section of the cable used to be too small, resulting in overload during operation. After long-term use, the cable's heat generation and heat imbalance cause heat generation. Wire and cable manufacturers3.
