How Does The Cold Shrink Tube Make Power Communication Safer?

In the field of power and communication, the protection of cable joints has always been a key link to ensure the stable operation of the system. Traditional protection methods are often limited by low efficiency and short life. With the advent of cold shrink tubes, these below problems that have long plagued the industry have been completely solved.

• Complicated operation: Traditional heat shrink tubes need to be installed with the help of heating tools. Not only is the risk factor of high-altitude operations high, but it is also easy to damage the cable. Cold shrink tubes do not require any tools. Just pull out the support tube to shrink automatically. The installation can be completed in 1 minute, and the efficiency is increased by up to 50%.

• Sealing failure: The tape winding method is prone to aging and cracking, resulting in moisture intrusion and short circuit. Relying on its elastic memory function, the cold shrink tube can fit the cable tightly, achieve IPX8 waterproof performance (can be immersed in water 1 meter without water seepage), and has excellent sealing performance.

• Poor adaptability: Ordinary heat shrink tube materials have weak weather resistance and need to be replaced frequently in complex environments. The cold shrink tube is made of silicone rubber or EPDM rubber, covers a diameter range of 6mm-200mm, supports special-shaped customization, and can adapt to extreme environments such as high and low temperatures, acid and alkali.

  
  

In addition, the cold shrink tube has the following advantages:

• After 1000 hours of UV aging test, it has excellent UV resistance, ozone resistance, aging resistance, acid and alkali resistance and other properties. The cold shrink tube can dynamically fit with the thermal expansion and contraction of the cable without cracking or brittleness. The excellent insulation performance of the rubber material eliminates the risk of leakage from the source.

• The cold shrink tube adopts a pre-expansion process, which can achieve 4-4.5 times expansion, and the wall thickness error is controlled within ±0.2mm to ensure uniform sealing. The cold shrink tube series produced by Volsun can fill the gap after installation and shrinkage, achieving zero intrusion of dust and water vapor (dustproof level IP6X).

• No professional tools are required during the installation process. Just put the cold shrink tube into the cable joint to determine the protection position, and then pull out the plastic support core. Even workers with no basic knowledge can quickly get started, greatly reducing labor and time costs.

The emergence of cold shrink tubing not only improves the protection efficiency of power and communication systems, but also provides a strong guarantee for the safe and stable operation of the industry. With its excellent performance, cold shrink tubing has become the preferred solution in the industry.
