What are the various indicators in cable production?

Cable is one of the important power equipment, and its quality and safety directly affect the stability of power system operation. To ensure the quality of the cable, various indicator tests need to be conducted. Below, we will introduce several important indicators in cable production.
1. Electrical performance indicators
Check whether its electrical characteristics such as resistance, skin effect, and inductance meet production and sales standards.
2. Mechanical performance indicators
Test the pressure resistance, bending resistance, and wear resistance of the product to ensure that it has strong mechanical properties during use.
3. Heat resistance performance indicators
The heat resistance of cables refers to the performance of wires or cables when operating at a certain temperature. The main consideration is the high temperature resistance and flame retardant performance of the cable.
4. Cold resistance performance indicators
The cold resistance of cables is very important in low-temperature environments. Mainly test the low-temperature bending performance, low-temperature bearing capacity, and low-temperature tensile strength of cables.
5. Corrosion resistance performance indicators
The corrosion resistance of cables is crucial in the presence of corrosive media. Usually, it is necessary to test the acid and alkali corrosion resistance, salt water resistance, etc. of cables.
6. Conductor resistance index
In the design and production process of cables, it is necessary to pay attention to the indicators of conductor resistance. The higher the conductivity, the higher the electrical energy carried by the cable. Therefore, it is necessary to test the resistance of the cable to ensure that it meets the design requirements.
7. Insulation thickness index
The insulation layer of a cable is an important part to ensure that wires and cables do not leak electricity. Therefore, it is necessary to pay attention to whether the thickness of insulation meets the standard requirements to ensure the safe use of wires and cables.
In summary, the above are various indicators in cable production, which are crucial for the quality and performance of cables. It is necessary to strictly follow standards and testing requirements during production and use.
