The basic requirements for cold-shrink cable accessories are: effective control of the electric field strength at the insulation shield break, reliable sealing and complete insulation protection against the external environment, sufficient mechanical strength, and good conductor connection.

How to measure the performance of a good cable accessory? The main points are as follows: Measuring a cable accessory's ability to achieve a long-term stable operating life from both electrical and physical performance perspectives. Electrical performance aspects include: resistance to partial discharge, effectiveness of electrical stress control measures, shielding structure of the cable joint, and weather resistance of the cable terminal. The effectiveness of electrical stress control measures can be measured by whether it effectively reduces the electric field strength at the internal and external interfaces, whether it helps improve other electrical performance, and whether it has been proven through long-term operation. Physical performance aspects include: waterproof sealing performance, mechanical protection performance of the joint, reliability of grounding connection, and the operating instructions and installation process of the heat-shrink cable accessory.

There are multiple factors in measuring the performance of cold-shrink cable accessories, but the main considerations are electrical and physical performance. For end users and operating departments, a stable and reliable long-term operating life is crucial. It is important to note some unique key factors of cold-shrink cable accessories and their significant impact on their performance.
