Detailed Content:
1. Product Overview
Our 1kV Cold Shrink Tubing is designed for insulation and waterproofing of low-voltage cable connections, splices, and terminations. Using advanced cold shrink technology, the tubing comes pre-expanded on a removable plastic core. Once positioned over the cable, removing the core allows the tubing to contract tightly and evenly around the substrate, creating a reliable, void-free seal — all without any heat source. This makes it ideal for field installations where torches or heat guns are impractical or unsafe.
2. Key Features & Benefits
Heat-Free Installation: No torch, heat gun, or open flame required – safer and faster to install, especially in confined or hazardous areas.
Reliable Insulation: Rated for 1kV systems, providing excellent dielectric strength for low-voltage power cables.
Waterproof Protection: Fully sealed design prevents moisture ingress, corrosion, and electrical tracking.
Multiple Colors Available: Red, yellow, blue, green, black, and more for easy phase identification, cable marking, or aesthetic matching.
Durable EPDM Material: UV-resistant, ozone-resistant, and flexible over a wide temperature range (-40°C to +90°C).
Consistent Quality: Factory pre-expanded to ensure uniform wall thickness and reliable shrinkage every time.

6. Installation Guide
Select the correct tubing size for your cable diameter.
Clean and prepare the cable surface.
Slide the cold shrink tubing (with core still inserted) over the cable or joint.
Position the tubing exactly where needed.
Hold the tubing firmly and slowly pull the plastic core out from one end.
Watch the tubing shrink evenly onto the cable.
Inspect for full recovery and proper sealing.
