Some cable faults can be checked physically, such as cable kinking, bending, and crushing. However, professional cable testing involves checking for cable harnesses assembly faults such as identifying copper corrosion, insulation cracks, and cables’ wetness. The need for cable testing is that the testing equipment and techniques help to rate your cabling quality, cable conformity, and functionality. The various methods used include;
- Measuring the general diameter
- Tensile test
- Persulphate test
- Conductor resistance test
- Annealing test
- The thickness of insulation test
- Wrapping test.

The Fascinating And Peculiar Applications Of Cable Testing Include;
1. Keeping Away Moisture
Institutions such as the Woods Hole Oceanographic Institute and National Oceanic and Atmospheric Association use their buoys to conduct their research on the deep ocean floor. These gadgets are powered by solar and rely heavily on the transmission of power and the exchange of signals to achieve excellent results. These moored buoys track the wind’s direction and speed, water’s temperature on the surface and subsurface, the temperature of the air, water current, and sunlight. The wire harness assembly used is made of thick rubber to prevent water from getting to the copper inside because of pressure. The cables split into fifty-foot sections that are interlinked to make them testable and maintainable. Hipot test is best in these situations.
2. Maintains High Voltage With Long Cables
Some people connect their scattered sensors or computers using long cables over long distances. Unlike modern cable test apparatus such as ohmmeters, automatic cable testers do not need adjustments, which ends up producing spurious data. The latter utilizes several rapid pulses to get resistant data and connection. Nonetheless, automatic cable testers are faced with parasitic capacitance due to the long-distance and end up taking more time to obtain a response, which also increases the time for testing. High voltage testing is encouraged since it will increase the VDC pulses that will make it possible to test for leakages and insulation properties. Safety should be paramount, for if anyone comes into contact with any end of the wire harness assembly, they will be subject to a lethal shock.
3. Asserting Dryness In Wiring System When Underwater
Firms such as the Boeing Company and Bluefin Robotics uses unmanned submarines of different sizes to serve multiple purposes. The underwater vehicles require some penetration spaces for the cable harness assembly that connects the external parts, i.e., electronic sensors, exterior cameras, and sonar is catered for while manufacturing. Testing is to detect any insulation defects or leakages.
4. Preservation Of Dummy Data
For the safety system test in vehicles, crash test dummies do a better job than human hands. There are multiple sensors (air pressure sensors, accelerometers, position sensors, temperature sensors, load sensors, angular rate sensors, and strain gauges) placed in areas near the most vulnerable body parts. The sensors connect to data acquisition modules with the cable harness assembly that need frequent testing and inspection before use.
5. Connector Panels For Events
Aside from the fun enjoyed in live concerts, much work is to ensure that the cables for speakers, lighting, mixer panel, cameras, video projectors, microphones, special effects control, laser, and power are perfect state. A CableEye test system is inclusive in a special large connector panel to test interconnected cables due to the wire harness assembly’s situation after manhandling.
