Performance of Heat Shrinkable Cable Accessories

2023-04-07
Heat Shrinkable Cable Accessories refer to various parts and components used to connect, support, and protect cables, including heat shrinkable straight through joint and heat shrinkable termination kit. The following describes several methods to identify the performance of Heat Shrinkable Cable Accessories:

1. Electrical performance: The main function of Heat Shrinkable Cable Accessories is to connect cables, so electrical performance is a key indicator to measure the performance of Heat Shrinkable Cable Accessories. Electrical properties include resistance, dielectric constant, insulation resistance, discharge strength, partial discharge and other parameters. The test methods include high voltage test, partial discharge test and so on.

2. Mechanical properties: The heat shrinkable cable accessories should bear the weight and external force of the cable, so the mechanical properties are also very important performance indicators. Mechanical properties include tensile strength, torsional strength, vibration life and other parameters. Test methods include tensile test, torsion test, vibration test, etc.

3. Corrosion resistance: Heat shrink cable accessories are usually installed in outdoor environment, need to have good corrosion resistance, can resist oxidation, ultraviolet, acid and alkali and other chemical erosion for a long time. Test methods include salt spray test, acid and alkali corrosion resistance test, etc.

4. Environmental performance: The heat shrinkable cable accessories shall meet the requirements of environmental protection, do not contain harmful substances, will not cause pollution to the environment. The test methods include ROHS detection and so on.

5. Production process: The production process of heat shrinkable cable accessories will also affect its performance, so the production process should also be considered. Production process including injection molding, molding, cold extrusion, etc., need to ensure that the process is stable and reliable, will not affect the performance and quality of the product
