Both cold-shrinkable cable accessories and heat-shrinkable cable accessories are divided into two categories: terminal and intermediate connection. Look at the product name to know where it is suitable for the cable, the terminal is used at the end of the wire and cable, and the intermediate connection is used at the middle section of the wire and cable. Today we will talk about the function of the cable accessory terminal.

When it comes to the function of the cable accessory terminal, the first thing that comes to mind is "insulation". The heat-shrinkable cable terminal is made of high-polymer composite polyolefin material, which has good electrical and mechanical properties, excellent technology and stable performance, and can well and uniformly improve the electric field distribution.

The high-voltage heat-shrinkable cable terminal has one more component than the low-voltage terminal-rain skirt, which is also an umbrella skirt, which is mainly used for rainproofing the end of the wire and cable. Therefore, the other function of the cable accessory terminal is waterproof. When the heat-shrinkable cable accessory terminal is shrink-wrapped on the cable after being heated, the internal hot melt glue will also melt, thereby tightly sticking to the cable accessories and the cable itself, which plays a good sealing and waterproof role. The rain skirt is fitted in the high-voltage outdoor terminal, there is no rain skirt indoors. Outdoor cable terminals can also be used in indoor places to increase insulation gaps, improve oxidation resistance, and protect welding points.

The function of the cable accessory terminal is mainly to connect a section of the cable with an electrical device. Both ends of the cable are sealed when they leave the factory, but they need to be cut and connected during installation. The cable accessories will play a role at this time, wrapping the cable and the connection to restore the previous sealing state.

The above is the main content of the function of the cable accessory terminal, but to make the cable accessory play its role, you must choose the cable accessory terminal suitable for your use environment. Not only must be distinguished according to the different levels of withstand voltage, the high voltage must be determined indoors or outdoors, and the specific square number of the cable must be determined so that the correct cable terminal can be accurately selected.
