High-voltage cables (HV cables) are used to carry high voltage electrical current. The components of these cables are designed to handle the high voltages, and they must be made from special materials. In addition to the insulator and conductor, there is often an outer sheath that protects everything else in the cable. This article will explain how these different parts work together to create a safe and effective HV cable.

The most important parts of the HV cable include the conductor, insulator, sheath, and armor. The materials used to make these components are either copper or aluminum. The conductor is made of copper or aluminum wire, which is then insulated with an insulating layer such as polyethylene (PE) or polyvinyl chloride (PVC). Finally, the cable is wrapped in an armor layer like steel (for mechanical protection) or aluminum alloy (for electric protection), which also provides a good thermal barrier between the conductor and outer insulation layers.

Conductor
The conductor is the part of the cable that carries electrical current. It can be made of either copper or aluminum, depending on your ...
... needs and budget. The conductor is insulated to prevent it from shorting out, and it's covered by a sheath to protect it from damage.
The materials used to make the conductor of the cable are either copper or aluminum. The difference between them is that copper has a higher specific resistance and is more expensive than aluminum, but it has a smaller electric resistance and is more durable than aluminum. Copper is soft, easy to process and beautiful, but it has low conductivity, which makes it difficult to be woven into complex shapes.
Aluminum has better conductivity than copper, so it can be woven into complex shapes with greater ease than copper. However, it also tends to be brittle and difficult to process. Aluminum also has a low melting point compared to copper, which means that its bending radius is limited.

Insulator
The insulator is the material that surrounds and protects the conductor. It prevents electrical current from passing through a cable, which could cause damage to equipment or injury to people. The insulator can be made of plastic, rubber or other non-conductive materials.
The insulation material used in electric vehicle high voltage cables is usually polyvinyl chloride (PVC). PVC has good electrical insulation properties; it can meet the requirements of thermal stability under high temperatures; It also has good mechanical performance and excellent chemical corrosion resistance with low water absorption rate; It can prevent moisture ingress into rubber insulation layers during long-term use; In addition, PVC has excellent weathering resistance performance under outdoor conditions without aging problems; Its surface smoothness plays an important role in improving electrical contact characteristics between wires and connectors when wire.

Sheath
The sheath is the outermost layer of your high voltage cable. It's made from rubber, polyethylene or polypropylene and protects the conductors from physical damage. The sheath can also be used as a conduit for other cables or wires that need to be run through it without damaging your HV cable.
The insulation around each conductor provides electrical protection against short circuits or overloads while still allowing current to flow through them smoothly. Insulation materials include glass wool, paper tape lamination (PTL), expanded polystyrene foam (EPSF), ethylene propylene diene monomer (EPDM) rubber compounds in addition to other materials like polyvinyl chloride (PVC).

HV cables are used to carry high voltage electrical current. They are also known as power transmission cables, and they're used in a variety of industries including mining, oil and gas production, wind and solar energy generation.
