WDZYJFE cable models are MVV22 cable and MVV32 cable, which are made of high-grade silane crosslinked polyethylene, and are suitable for power frequency line voltage of 0.6/ 1k power transmission and distribution system. The maximum working temperature of the conductor shall not exceed 250 degrees Celsius, and there is no need to preheat the cable when the ambient temperature is not lower than 0 degrees Celsius.
Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables and aluminum cables. It is composed of single or multiple wires and insulation layer, which is used to connect circuits, electrical appliances, etc.
Extended data:
The manufacture of wires and cables is completely different from the production mode of most electromechanical products. Mechanical and electrical products usually adopt the method of assembling another part into a part and assembling multiple parts into a single product, and the products are measured by unit or number. Wires and cables are based on length.
All wires and cables are made of conductors, and insulation, shielding, wiring and protective layers are added layer by layer around the conductors. The more complex the product structure, the more layers are superimposed.
The quality management of wires and cables must run through the whole production process. The quality management inspection department should inspect the whole production process, the operators should conduct self-inspection and mutual inspection between the upper and lower processes, which is an important guarantee and means to ensure product quality and improve the economic benefits of enterprises.
The main processes of wires and cables are drawing, twisting and coating. The more complex the specification, the higher the repeatability.
