Cable is a general term for ropes, wires covered with insulators and protective sheaths, and optical fibers. Those made of iron or steel wire are also called iron cable or steel cable.

In today's world, where various machines and devices have become electronic, cables such as electric wires and optical fibers have become very important elements. For example, in automobiles, computers are used to control automatic transmissions and engines, and cables are also essential to operate power steering, power windows, and other electronic devices in the car. Automobiles usually use wiring harnesses, which are components made up of several bundled cables.

Tests on cables include withstand voltage tests in which high voltage DC and AC currents are applied, insulation resistance tests, and tests to determine the bending strength of cables. These tests are conducted to check the power transmission efficiency to ensure that in-vehicle equipment operates properly and to check the strength of the cables to ensure that they are not damaged by vehicle movement or vibration.

Matsusada Precision has a lineup of high-voltage power supply equipment that applies voltage to these cables, as well as X-ray non-destructive testing equipment that can check for cable breaks.
