Automotive wire cable insulation

The rubber insulator that surrounds the automotive wire cable serves to protect the cable's conductor from outside elements. Automotive wire cable, which is insulated with either PVC (Polyvinyl Chloride) or XLP (Cross-Linked Polyethylene), is highly resistant to high temperatures, abrasion, and oil. Welding cables insulated with Neoprene and EPDM, which are also resistant to heat, abrasion, and solvents, are sometimes used in place of automotive wire cable.

PVC

PVC has good resistant to grease and oil and has a temperature rating of 80°C. Automotive wire cable insulated with PVC is commonly used for wiring relay boxes, signal lights, and audio systems. PVC is manufactured with several different classifications with minor specification changes. Standard PVC has a high level of resistance to cuts and tears. Semi-rigid PVC is tougher and has greater resistance to abrasion, but it is less flexible than standard PVC. Irradiated PVC is cross linked by means of irradiation. Irradiated PVC has good abrasion and chemical resistance.

XLP

XLP or XLPE (cross-linked polyethylene) is typically more expensive than PVC insulated automotive wire cable. XLP is resistant to chemical corrosion and has an upward temperature rating of around 125°C. XLP insulated automotive wire cable is safe for wiring electrical components near the engine compartment of a vehicle. XLP insulated automotive wire cable is also more durable than PVC and is relatively lighter in weight.

CPE

Neoprene and EPDM are common insulators for welding cables, which are highly durable and flexible with resistance to abrasion, extreme temperatures, and solvents. Neoprene and EPDM welding cable is often used in similar applications as automotive wire cable, since it has an advantage in situations where flexible cables are preferred. The disadvantage in using welding cable instead of automotive wire cable is that it is not as resistant to oil and petroleum-based fuel.
