- Product Introduction
0.6 1 1.8 3 kV indoor cold shrink cable terminal tube made from high-quality liquid silicone rubber, the product is available in 3-core, 4-core, and 5-core configurations,Cable Cross-Section Range: 25–400 mm²,primarily designed for low-voltage cable terminations and intermediate connections.
Cold shrinkable cable tube are pre-expanded, rubber-based components used for insulation, sealing, and mechanical protection in cable joints and terminations(dry, low-pollution areas).
● Unlike heat-shrink products, they do not require heating for installation-instead, they rely on elastic memory technology to shrink tightly onto cables when the supporting core is removed.
● Unlike outdoor versions, they prioritize compact design, ease of installation, and cost efficiency while maintaining reliable insulation and sealing.

Advantages vs. Heat-Shrink & Other Methods
| Feature | Cold Shrink | Heat Shrink | Taped Joints |
|---|---|---|---|
| Installation | No heat/tools | Requires torch | Manual wrapping |
| Sealing Performance | Excellent | Good | Moderate |
| Weather Resistance | High (silicone) | Moderate (PE) | Low |
| Reusability | No | No | Yes (if undamaged) |
| Speed of Installation | Fast (5–10 min) | Slower (heating) | Slow (skill-dependent) |
Installation Steps (Simplified)
1. Prepare Cable – Strip insulation, clean, and apply semi-conductive tape if needed.
2. Slide Cold Shrink Onto Cable – Ensure correct orientation.
3. Remove Support Core – Pull the spiral core to trigger shrinkage.
4. Secure & Seal – Verify tight fit and use mastic for extra moisture protection.
Applications
● Electrical Panels – Terminations in switchgear, MCCs.
● Data Centers – LV cable joints for server racks.
● Industrial Plants – Motor connections, conveyor systems.
● Commercial Buildings – Risers, distribution boards.
FAQs
Q: Can cold shrink be reused?
A: No-once installed, it cannot be repositioned.
Q: Can indoor cold-shrink be used outdoors?
A: No-lacks UV weather resistance. Use outdoor-rated products.
Q: How long does it last?
A: 20+ years (depending on material and environment).
Q: Is it safer than heat shrink?
A: Yes-no open flame or hot tools required, reducing fire risks
Q: How to verify proper installation?
A: Check for uniform shrinkage and no gaps (use dielectric grease if needed).
