Stability of Cable Fault Detection The conductive core of the cable mainly transmits electrical energy or electrical signals. The resistance of a wire is the main indicator of its electrical performance. When an AC voltage is applied, the core resistance is greater than the DC voltage due to the skin effect and the proximity effect surface.

Stability cables used only for cable fault detection The conductive core of the cable mainly transmits electrical energy or electrical signals. The resistance of a wire is the main indicator of its electrical performance. When an AC voltage is applied, the core resistance is greater than the DC voltage due to the skin effect and the proximity effect surface.

It is only used to test whether the DC resistance or resistivity of the wire core exceeds the standard specified value. Through this inspection, some defects in the production process can be found, such as broken wires or some single wires. Standard; incorrect product length, etc.

Cable fault detection? Insulation resistance test: The type of insulation resistance is an important indicator reflecting the insulation characteristics of wire and cable products, and is related to the electrical strength of the product. Dielectric losses and the gradual deterioration of insulating materials under operating conditions are closely related. For communication cables, insulation resistance between conductors that is too low increases loop attenuation, crosstalk between circuits, and long-distance power leakage across the conductor cores.

Therefore, the insulation resistance should be higher than the specified value, cable fault detection, stability test. Aging test is a stability test used to determine if performance can remain stable under stress (mechanical, electrical and thermal). Shenzhen Longgang Cable Fault Detection Co., Ltd. conducts thermal aging test: A simple thermal aging test is to test the aging characteristics of the tested product under the action of heat.

At higher temperatures T, shorter lifetimes are obtained.
