PVC power cable

PVC insulated sheathed cables can be divided into lightweight PVC insulated sheathed cables and heavy-duty PVC insulated sheathed cables. Among them, the insulation layer and sheath layer of lightweight cables are relatively thin and suitable for general places; The insulation layer and sheath layer of heavy-duty cables are relatively thick, suitable for harsh environments such as high temperature, low temperature, strong acid, and strong alkali.

Basic structure:

Core: As the conductive part of power cables, it is used to transmit electrical energy and is the main part of power cables.
Insulation layer: This layer electrically isolates the wire core from the ground and between wire cores of different phases, ensuring the transmission of electrical energy. It is an indispensable component of the power cable structure.
Protective layer: Its function is to protect power cables from external impurities and moisture intrusion, as well as prevent direct damage to power cables by external forces.

Features:

Excellent insulation performance: Polyvinyl chloride has good electrical insulation performance, which can effectively isolate the conductors in the cable, ensuring the stability and safety of power transmission.
Strong chemical corrosion resistance: Polyvinyl chloride has good resistance to acid and alkali, oil, salt water and other chemical corrosion properties, and can be used for a long time in harsh environments.
High mechanical strength: Polyvinyl chloride has high tensile and compressive strength, and can withstand certain mechanical stress and external impact.
Good flame retardant performance: PVC insulated sheathed power cables have good flame retardant performance, which can effectively prevent the spread of fire and reduce the harm of fire.

Application field:

Building power system: used for wiring of power supply systems in residential and commercial buildings, ensuring the stability and safety of power supply.
Industrial power system: suitable for power transmission and distribution in large power systems such as factories and mines, capable of withstanding large loads and mechanical stresses.
Wind and solar power plants: PVC insulated sheathed power cables are suitable for power transmission and connection in wind and solar power plants.
