The life of the cold shrinkable cable accessories

Release date:2018-12-06 author:admin Click:

When you buy something, everyone will notice the shelf life of the goods you buy, and no one wants to buy expired products. The same is true of the heat and cold shrinkable industry. Our sales staff often encounter problems with customers asking about the life of the cold shrinkable cable accessories.
 
It is true that
the life of the cold shrinkable cable accessories is shorter than that of heat shrinkable cable accessories and is more affected by the environment. So what factors will affect the life of the cold shrinkable cable accessories? Let me tell you today.
 
One of the first factors affecting
the life of the cold shrinkable cable accessories is the raw material produced. The cold shrinkable cable attachment is injection molded from a high-elastic material such as silicone rubber in a mold, and then internally supported by a spiral plastic support strip. When the rod is pulled out during use, it will shrink at room temperature. The contraction principle of the cold shrinkable cable attachment is actually the same as the rubber band we usually use. But if staying in the state of expansion for too long, it will lose flexibility. Therefore, the life of the cold shrinkable cable accessories that has been expanded is very short, and it is best to use it within a year or so.
 
The electrical and physical properties of the cold-shrinkable product itself also affect
the life of the cold shrinkable cable accessories. The anti-discharge performance determines whether the interface discharge air gap and the air gap defect of the body can be effectively avoided. The ability of electric field control is related to whether it can effectively reduce the electric field strength of the inside and outside to help reduce partial discharge and long-term safe operation.
 

The life of the cold shrinkable cable accessories is also related to the storage and use environment. Cold shrinkable cable accessories are stored in a place that is protected from direct sunlight and dry and tidy. Otherwise, the aging of the cold shrinkable cable accessories will be accelerated, such as cracking and shrinkage.
 
Through the above introduction, we must understand the main influencing factors of
the life of the cold shrinkable cable accessories, we must pay attention to these aspects in the procurement process. If there are any product problems during the use, please contact our customer service staff in time, we will do our best to solve it for you!
