Common Problems With Cold Shrink Cable Accessories

Cold Shrink Cable Accessories is small in size and does not require special tools to operate. It is convenient, simple and fast. It has the advantages of wide application range and small and fine product specifications. Due to the raw materials of silicone rubber, cold shrink products can have a lasting radial pressure on the cable itself, so as to achieve thermal expansion and contraction synchronized with the cable itself, thereby ensuring long-term and reliable operation of the cable. With the widespread use of cold shrink cable accessories, it has also brought confusion in the price and quality of some cold shrink products on the market. Today, the editor will tell you about the common problems of cold shrink cable accessories.

Common problem 1 of cold shrink cable accessories:

The direction of the terminal is not correct. Due to the production level or careless installation, the direction of the terminal may be incorrect. When the cable is installed on the equipment, the terminal should be in close contact with the contact surface of the casing. If the terminal is not correct, there will be a gap, and even the surface contact will become a line contact, which will increase the contact resistance. In this way, it will heat up and burn the equipment after long-term operation.

Common problem 2 of cold shrink cable accessories:

The product loses elasticity during installation. Cold shrink cable accessories are made of highly elastic materials such as silicone rubber and ethylene propylene rubber. If they are in a state of high tension for a long time, they will lose their elasticity like the rubber bands we use, and will not be able to shrink back to their original position after letting go. Therefore, cold shrink cable accessories must be guaranteed to be within the storage period, which is generally about one year, so customers must ask clearly to confirm the shelf life before purchasing.

Common Problems of Cold Shrink Cable Accessories 3:

Strip off all semi-conductive layers. When making cables on site, some staff may strip off all the semi-conductive layers above the three-finger gloves. After the cable is made in this way, there will be induced electricity on the cable surface between the stress tube and the stress cone. In this case, the ground wire of the cold shrink cable joint should not be connected. If it is connected and it runs for a long time, the section of the cold shrink cable accessory with induced electricity will discharge to the ground wire, and in severe cases it will burn or even burn out.
