automotive wiring cord

Use automotive wiring when installing electrical parts such as marker lamps, vehicle height lights, and work lights. Since the wire thickness varies depending on the allowable current, it is necessary to use it properly depending on the part to be installed.

Types of automotive wiring

Wiring used in automobiles is exposed to harsh environments such as high and low temperatures, vibration, rainwater, and unintended friction. Also, unlike household power supplies, power is transmitted from 12V/24V DC batteries, so dedicated wiring must be used.

Automotive wiring includes "high-voltage wires for automobiles" and "low-voltage wires for automobiles." "High-voltage wires for automobiles" are used for mechanisms that require high voltage, such as ignition and hybrid motors, while "low-voltage wires for automobiles" are used to attach electrical parts such as car navigation systems.

Furthermore, low-voltage wires for automobiles are divided into three types: "low-voltage wires for automobiles (AV)", "thin-walled low-voltage wires for automobiles (AVS)", and "ultra-thin low-voltage wires for automobiles (AVSS)".

How to choose automotive wiring

Wires for automobiles are sold with different allowable currents and wire thicknesses. A unit called "sq (square)" is used to express the cross-sectional area of the core wire for low-voltage wires for automobiles, and the cord size and allowable current are determined based on this unit.

When purchasing wiring, understand the current used by the electrical parts to be installed in advance and select the appropriate one.
