1. During the storage period of the cable, it should be rolled regularly (once every 3 months in summer). When rolling, the side of the lower storage plate should be rolled up to prevent the bottom surface from being damp and rotten, and to make the insulating liquid inside the cable evenly distribu...

The breakdown test of the cable is to increase the voltage step by step until the insulation breakdown, and obtain the breakdown voltage value of the cable. The purpose of this type of test is to assess the safety margin between the ability of the cable insulation to withstand voltage and the indust... READ MORE

The conductors in the symmetrical cable are generally copper wires with a wire diameter of 0.25 mm to 1.4 mm. The diameter of the symmetrical cable used in the city is usually 0.4 mm to 0.9 mm; the diameter of the symmetrical cable used for long distance is usually 1.2 mm. Symmetrical cables with al...

Symmetrical cables are manufactured from pairs of twin conductors called cores within a protective jacket. In order to reduce the interference between each pair of wires, each pair of wires is made into a twisted shape, which is called twisted pair. The twisted pair is two copper wires with a diamet...
