In a modern car, all major systems depend on the presence of electricity: lighting, air conditioning, audio systems, alarms, navigation and others. That is why every such vehicle uses a large number of wires that must withstand various negative external factors. They are affected by the fuel and the oils us

ed. The wires also have to withstand various mechanical influences. In the wiring of modern vehicles are usually used automotive wires brands PGVA, PVA, PVAM. These wires are sometimes removed from junk cars in ajax.

Features of different types of automotive wires:

PGVA wires are highly flexible and correspond to class 3 on this indicator. They can be used at temperatures from – 40 to + 70 degrees. These products are recommended for agricultural machinery and on-board machinery.
PVAM wires correspond to the 5th class of flexibility. They can be used at temperatures up to + 105 degrees and even in such conditions they will keep their primary characteristics. Service life of such products is 10 years. This type of wires is suitable for on-board machinery, cars and trucks.
Automotive wires have the following advantages:

resistance to gasoline, acids and machine oil, as well as diesel fuel;
suitability for use at any temperature;
resistance to shocks;
resistance to wear;
These properties of automotive wires are explained by the use of copper wire with a circular cross-section in their pr

oduction. It acts as a cable that conducts current. Due to the large number of strands, high reliability of wires and protection under heavy loads is ensured. Also of great importance to ensure the long-term operation of any automotive wires is the use of a special insulating material РPVC plastic, which is highly resistant to wear and aging. For the insulation of power wires, durable rubber is used.

Wires that are characterized by low voltage are usually used in on-board systems of cars. To protect against shock and other damage, they can be insulated with armor. Braid shielding is used to reduce radio interference. Wires are assembled into harnesses that also include caps, braids, lugs, and other accessories before being installed on the vehicle.

When selecting the wire cross section for the harness, consider the temperature of the environment, the temperature load on the wires, the number of wires, and the design of the harness itself. A different type of wire is provided for each vehicle, which increases the quality of the car’s operation.
