Why Choose Silicone Cold Shrink Tubing?
Silicone cold shrink tubing has rapidly become the go-to solution for engineers facing demanding sealing and insulation challenges across 5G base stations, new-energy power equipment, and industrial waterproofing applications. Its combination of ultra-high expansion ratios, extreme environmental durability, and tool-free installation delivers up to a 50 % improvement in sealing effectiveness compared to traditional heat-shrink tubing or sealing tapes. Below, we delve into its core advantages, technical specifications, diverse application scenarios, and best-practice installation techniques—backed by industry data and product standards.
Core Advantages:
1.Ultra-High Expansion Ratio: Achieves 4:1 to 5:1 shrink ratios, accommodating cable diameters from 25mm to 70mm, ensuring tight wrapping around joints to eliminate water ingress risks.
2.Extreme Environment Durability: Operates stably from -60°C to 200°C, resists salt spray, UV radiation, and ozone, with a lifespan exceeding 10 years.
3.Double Installation Efficiency: Tool-free operation—pull the core rope to complete sealing in 2 minutes, saving 70% labor time.
5G Base Station Waterproofing
Pain Point: Outdoor feeder connectors prone to water ingress, causing signal attenuation.
Solution: Silicone cold shrink tubing with embedded sealant forms a dual-layer waterproof barrier, achieving IP68 rating and extending equipment lifespan.
Power Cable Terminal Protection
Pain Point: Oxidation at high-voltage cable joints leading to short circuits.
Solution: High-elastic silicone material applies continuous radial pressure, resisting arc punctures with a tensile strength of 9.8MPa.
Industrial Waterproof Sealing for New-Energy Equipment
Pain Point: Solar inverters, battery racks, and wind-turbine cabling demand robust sealing against UV, salt fog, and temperature swings.
Solution: Cold shrink tubing’s material stability—from –60 °C to +200 °C—and resistance to ozone and salt spray make it ideal for renewable-energy installations exposed to harsh climates
Installation Process
Preparation: Verify that cable jackets and connector surfaces are clean and dry.
Slide-On: Slide the tubing, still expanded around its removable core, onto the cable assembly until it fully overlaps the splice or connector.
Core Removal: Pull the core rope smoothly; the tubing will contract uniformly and conform tightly to the substrate within seconds.
Inspection: Ensure no voids or wrinkles remain. A proper seal will exhibit continuous contact around the circumference.
