Brake Cable and Trailer Cable

Automotive Wire Brake Cable

It is common knowledge that brakes slow down or stop a vehicle. They are a vital component of every automobile. However, the wire and cable industry knows that brake cable is just as important as the brakes themselves.

Brake Cable Applications

Automotive wire brake cable may be used in electric brake, automotive, truck, or trailer applications. For example, automotive emergency brakes usually have a brake cable connecting the brake mechanism to a lever that can be triggered by the driver. For cable-operated brake actuators, a brake cable is linked to a lever at each end. If a brake cable is damaged severely enough, your brakes could fail, so it is important to maintain brake cable properly.

Brake Cable Construction

Brake cable typically has a bare copper conductor and a PVC jacket. It is available in a variety of gauge sizes, wall thicknesses, and number of conductors. Brake cable is offered in a variety of colors for easy identification.

Automotive Wire Trailer Cable

Another type of automotive wire, trailer cable, may be used in automotive trailers, caravans, and trucks, or in other applications that require resistance to weather, oil and grease.

Connecting a Trailer to the Pulling Vehicle's Electrical System

Trailer cable is often used to connect trailers to the electrical systems of the cars or trucks they're attached to. This is done so that other drivers can see the brake lights and turn signals of the pulling vehicle.

Certain trailers, like tractor trailers, RVs, and horse trailers, also have side lights and interior lights. In these cases, the trailer cabling is much more complex. For a small trailer only needing brake lights and turn signals, only three trailer cable circuits are necessary: one for the tail lights, one for the left brake light and one for the right brake light. In some vehicles meant for towing, a wiring harness comes rigged and can be plugged right into the pre-made plug on the trailer. Other vehicles must be wired with trailer cable by hand.

Trailer Cable Characteristics

Trailer cable is constructed to resist wear and retain flexibility and durability in extreme conditions. Trailer cables are generally resistant to common automotive fuels, oils, and greases. For fleets that run in extreme temperature ranges, trailer cable is a superb cable replacement.

Trailer Cable Construction

Trailer cables commonly use stranded copper conductors that are insulated for flexibility, abrasion and tear resistance. Trailer cable is usually color-coded for identification purposes with a PVC jacket or even color coded to ATA specifications. In extremely low temperature requirements, TPE can be substituted for PVC. Between trailer cables, stranding, insulation thickness, and jacket thickness vary. Amp ratings will typically fluctuate according to the trailer cable application.
