What Needs to Wire and Cable Detection

Wires and cables have a fixed lifespan. If you are not careful, it is easy to cause short circuits and fires. Therefore, regular inspections of the wires and cables are required. The inspection of the wires and cables needs to start from two aspects of resistance and voltage.

1. Resistance detection of wires and cables
In the resistance detection of wires and cables, it mainly covers DC resistance detection and insulation resistance detection. Among them, the direct current resistance detection is mainly through the resistance value detection experiment on the electrical conductivity of the wire and cable, which measures the direct current resistance value of the wire and cable to ensure a comprehensive analysis of the quality of the wire and cable core. For example, the maximum resistance of wires and cables under the relevant standards is limited at 20°C. The detection test is used to calculate whether the value of the residual resistance of the wires and cables meets the corresponding standard range. If the value is lower or higher than the specified range Numerical value, which means that wire and cable products cannot meet the requirements. Similarly, the insulation resistance test of the wire and cable is mainly to ensure the safety of the use of the wire and cable. The insulation test is to measure the value of the leakage current of the actual operation of the wire and cable product, which is mainly used for the current insulation by applying high resistance The measured value of the insulation resistance of the wire and cable is helpful for the safe use of the wire and cable products.

2. Voltage detection of electric wire and cable
In the voltage detection of wires and cables, it is mainly to withstand various types of damage to the alternating current voltage. In addition, it is necessary to regularly train inspectors, and through reasonable training methods, the comprehensive ability of inspectors will be further improved to ensure that they can be competent for lifting machinery inspection tasks and ensure the smooth progress of inspection operations.
