Materials for making Cold Shrinkable Cable Accessories

Cold shrink cable accessories, as a kind of electrical accessories widely used in the fields of power, communication and transportation, its unique cold shrink technology makes the cable connection more simple and fast. All this is inseparable from its high-quality material base. So, what materials are the cold shrink cable accessories made of?

First of all, the cold-shrink cable accessories mainly use elastomer materials as their main structure. Among them, silicone rubber and ethylene propylene rubber are the two most common materials. Silicone rubber is widely used in the manufacture of cold shrink cable accessories because of its excellent electrical insulation properties, weather resistance, aging resistance, anti-fouling and anti-creepage characteristics. The ethylene propylene rubber has become a substitute for silicone rubber in some special occasions because of its good oil resistance, weather resistance and chemical corrosion resistance.

Secondly, in the manufacturing process of cold shrinkable cable accessories, you also need to use some auxiliary materials. For example, in order to easily fit a pre-expanded cold-shrink tube over a cable at a construction site, plastic screw supports are often added inside the tube. These supports, after being drawn out, can make the cold shrink tube closely fit on the cable under the elastic effect of the rubber, thus forming a good electrical connection.

In addition, the cold-shrink cable accessories also need some other auxiliary materials, such as cable joints, grounding devices, etc. The selection of these materials also needs to take into account factors such as their electrical properties, physical properties and the environment in which they are used. For example, the cable joint needs to have good electrical conductivity and mechanical strength to ensure the stability and reliability of the cable connection; The grounding device needs to have good grounding performance and corrosion resistance to ensure the safe and stable operation of the cable system.

In summary, the cold shrinkable cable accessories are made of elastomer materials such as silicone rubber, ethylene-propylene rubber and some auxiliary materials. These high-quality materials ensure that the cold shrink cable accessories have good electrical properties, physical properties and performance, so as to meet the needs of cable connections in a variety of complex environments. At the same time, with the continuous development and progress of material science, it is believed that the materials of cold shrink cable accessories will be more diversified and high performance in the future, providing more solid support for the development of power, communication and transportation and other fields.
