Silicone rubber cold shrink tube, specifically designed for photovoltaic connectors, is an insulating sleeve made from special silicone rubber, pre-expanded over a removable support tube. Its very high expansion ratio allows it to accommodate the radial size differences between photovoltaic connectors and optical cables. When in use, simply position it and remove the support tube. It utilizes its radial shrinking force to form a tight encapsulation, providing insulation, dust prevention, waterproofing, and sealing effects.
Features
• Continuous operating temperature: -55°C~180°C
• Shrink Ratio : 6:1 or so .Suits for an extensive range of cable sizes because of the shrinkage
• Retains its resiliency and pressure even after prolonged years of ageing and exposure, seals tight against moisture and water
• Good weather resistance, ozone ageing, ultraviolet and salt mist corrosion resistance, performs stably under long-period exposure to the sun
• Simple installation, requires no special heating tools , and adhesive to seal the connections
• Standard color: black(Other colors can be customized)
