Protection of communication and power cable connectors has always been a key focus in the industry. While traditional heat shrink tubing has solved the sealing problem to some extent, its reliance on tools, temperature sensitivity, and poor adaptability make it unsuitable for complex outdoor and industrial scenarios.
Volsun's high-ratio silicone rubber cold shrink tubing offers a new solution for connector sealing with its unique advantages. Simply put, this cold shrink tubing uses specially formulated silicone rubber to achieve an expansion ratio of approximately 5 times, can be used continuously in a temperature range of -60℃ to 200℃, and can achieve a tight seal without heating, making it an ideal choice for protecting various connectors.
Let's take a closer look at its advantages:
High-Ratio Adaptability: With an expansion ratio of 5 times, it can cover different connector diameters from 6.0 to 72.0 mm, tightly wrapping irregularly shaped and multi-strand cable connectors without cutting. Its strong resilience provides sustained radial pressure, ensuring it won't loosen over long-term use and preventing moisture and dust intrusion, making it suitable for humid and dusty outdoor conditions.
Excellent weather resistance: In addition to a temperature range of -60℃ to 200℃, it also boasts superior weather resistance, resisting sun exposure, UV rays, and salt spray corrosion. It won't crack even after long-term outdoor use, providing more reliable protection for communication base station cables in coastal and rainy areas.
Highly efficient installation: Automatic shrinkage is achieved by simply pulling out the support, eliminating the need for heating or hot melt adhesive, ensuring a one-step sealing of the joint. Tear strength ≥ 35kN/m, puncture resistance, and mechanical damage resistance make it less prone to breakage during construction and maintenance.
Furthermore, this kind of cold shrink tube has a Shore A hardness of 40±5, tensile strength ≥ 9.0MPa, elongation at break > 800%, 200% tensile stress ≤ 2.0MPa, and tear strength ≥ 35kN/m. These data fully demonstrate its balanced flexibility and support, high tensile strength, high ductility, low stress design, and resistance to punctures and tears, enabling it to adapt to various complex application scenarios.
This cold shrink tubing is primarily suitable for multiple fields such as telecommunications engineering, power cables, cable television, and industrial equipment. As the manufacturer, Volsun cold shrink tubing supports customized sizes and packaging to meet various connector requirements. Furthermore, all product performance indicators meet national standard testing and have been mass-produced and applied in large-scale projects in telecommunications, power, and other industries.
