Innovative Approach: Volsun applies high shrink ratio silicone rubber cold shrink tubes to the photovoltaic industry.

The high-ratio silicone rubber cold shrink tubing developed by Volsun has been widely used in the field of insulation protection of communications and electrical equipment due to its excellent sealing, weather resistance, heat resistance, abrasion resistance and salt spray corrosion resistance. Now, Volsun innovatively applies this material to the waterproof and moisture-proof protection of M4C connectors in the photovoltaic industry, which not only improves the protective performance of the connector, but also injects new vitality into the photovoltaic industry.


 
In order to verify the anti-salt spray corrosion performance of silicone rubber cold shrink tube, Volsun conducted a rigorous salt spray test. In an 80% salt spray environment, the metal with silicone cold shrink tube protection and the bare metal sheet were exposed for 72 hours. The following testing photos are for reference.



The results showed that the metal sheet with the silicone rubber cold shrink tube had no obvious rust, while the bare metal sheet had severe corrosion. This result fully proves the excellent performance of silicone rubber cold shrink tube in anti-salt spray corrosion.

 

Our cold shrink tubing has excellent waterproof and moisture-proof properties. During installation, the cold shrink tubing is placed close to the surface of the M4C connector to form a sealing layer, effectively preventing moisture intrusion and improving protection performance. The actual waterproof level reaches IP X8. With strong weather resistance, the cold shrink tubing can maintain stability in harsh environments and is not prone to aging, ensuring the reliability of the connector for long-term outdoor use. It is easy to install, without the need for special tools, and greatly reduces installation time and subsequent maintenance costs. These advantages of cold shrink tubing have enabled us to make new breakthroughs in the application of the photovoltaic industry.
 
This innovative product of Volsun has been recognized by photovoltaic industry professionals. An engineer said that this cold shrink tube provides an effective protection solution and significantly improves the reliability and safety of the connector. 
Looking forward to the future, Volsun will continue to exert its innovative spirit, explore applications in more fields, and bring more surprises to the industry.

Volsun's silicone cold shrink tube not only improves the protective performance of M4C connectors in the photovoltaic industry, but also demonstrates how to apply existing product innovations to new fields. This is not only a technological breakthrough, but also a paradigm shift in thinking.
