Technical requirements of frequency conversion cable

In the production process of special cable for variable frequency motor, the process of extruding insulated core into cable is the most critical process.

The quality of insulated wire core will directly affect the electrical performance of cable. In order to improve the cable quality, we choose insulation materials with high electrical properties, such as 1.8/3kv special cable for variable frequency motor, 10kV cross-linked insulation material, 6/ 10kv special cable for variable frequency motor, 35kv cross-linked insulation material and imported materials. In the production process, special attention is paid to the purification of raw materials, the shielding and insulation materials are tightly wrapped, and the insulation eccentricity and insulation outer diameter are uniformly controlled, which can reduce the interface effect and improve the electrical performance of the cable.

The frequency conversion cable in the cable manufacturing process requires structural symmetry. When making cables, the tension of insulated core wires must be uniform, so that the length of core wires after making cables is as consistent as possible. Otherwise, it will cause structural changes, lead to uneven capacitance and inductance, and affect the electrical performance of the cable.
