◆ Based on the completely symmetrical space structure design, the cable has excellent electromagnetic compatibility;

◆ Low and uniform positive sequence and zero sequence impedance, which greatly improves the quality of power supply compared with ordinary four-core;

◆ Environmental temperature for cable laying： PVC insulation and XLPE insulation shall not be lower than 0℃;

◆ The maximum operating temperature of the cable conductor ： 70°C for PVC insulation and 90°C for XLPE insulation.

◆ This product is suitable for power lines and transmission and distribution lines with strict requirements on shielding performance, especially suitable for power supply or connection cables in variable frequency control transmission systems with rated voltages of 1.8/3kV and below. The frequency conversion cable is actually a shielded power cable. The difference is that the ground wire is divided into three parts and placed between the three main wires to achieve a uniform electric field to improve the electromagnetic radiation level of the cable. It is mostly used to connect the power supply of high-power frequency converters and frequency conversion motors.
