Volsun Innovative Cold Shrink Tube Leading A New Era of Photovoltaic Connector Protection

In the realm of solar power generation, photovoltaic connectors play a crucial role in linking essential equipment like solar panels, combiner boxes, controllers, and inverters. The quality of their performance significantly impacts the efficiency and safety of the entire solar power system. Yet, a recent report from the "Solar Bankability" project team of the European Union's Horizon2020 program reveals that the risk of damage and overheating of photovoltaic connectors is the second highest technical failure risk among power stations. This data underscores the need for a thorough examination and enhancement of these vital components.

Essential Performance Requirements for Photovoltaic Connectors

1. Electrical Conductivity: Solar panel connectors should have superior electrical conductivity to maintain contact resistance below 0.35 milliohms, reducing energy wastage and enhancing system efficiency.

2. Safety Features: Due to exposure to varying outdoor conditions, solar panel connectors must be waterproof, heat-resistant, UV-resistant, corrosion-resistant, and highly insulated. They should meet IP68 standards to withstand extreme weather.

3. Structural Integrity: Connectors must be designed for durability and reliability during use. For instance, the MC4 connector should be able to handle 39 amps of current while keeping its operating temperature below 105 degrees Celsius for long-term stability.

Solutions for Photovoltaic Connector Failure

In the face of photovoltaic connector failure, Suzhou Volsun Electronic Technology Co., Ltd., with its keen market insights and extensive technical expertise, has introduced the RUBLS-SILIC high-rate silicone rubber cold shrink tube, providing a comprehensive protection solution for photovoltaic connectors.

Advantages of High Shrink Ratio Silicone Cold Shrink Tubing

1. Temperature resistance range: Made of high-quality silicone rubber material, it can be used continuously in a wide temperature range from -60°C to 200°C, ensuring reliability under extreme climate conditions.

2. Expansion rate: The expansion ratio is about 6 times, adapting to the connection sealing of different diameters, ensuring the sealing and waterproof and moisture-proof performance of the connection point.

3. Weather resistance: After 1,000 hours of UV irradiation, there are no cracks on the surface.

After another 72 hours of salt spray corrosion resistance test, the protected metal is observed to be free of rust, showing excellent weather resistance and corrosion resistance.

4. Physical and mechanical properties: The tear resistance is high, measured at about 36kN/mm, ensuring the stability and durability of the material when encountering external forces.

5. Easy to install: There is no need to heat or use special tools, and the installation can be completed by simply pulling out the support strips, which greatly simplifies the construction process and saves time and labor.

Volsun's RUBLS-SILIC high shrink ratio silicone rubber cold shrink tube is the perfect solution for safeguarding connectors and cables in solar power plants. Its exceptional heat and weather resistance, along with its strong physical and mechanical properties, make it an excellent choice for various environments. Whether it's the scorching desert, humid coast, or freezing mountains, this cold shrink tube ensures the smooth operation of solar systems.
