Cold Shrink Tape, Tubing

1. Overview

Cold shrink materials are pre-stretched elastomeric products used for cable insulation, sealing, and mechanical protection. Unlike heat shrink alternatives, they require no heating equipment during installation, making them ideal for field applications. Their importance in modern technology stems from their reliability in harsh environments, compliance with international safety standards, and role in minimizing downtime in critical infrastructure.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Cold Shrink Tubing	Radial recovery force, UV resistance, flame retardant	Power cable splices, fiber optic protection
Cold Shrink Tape	High dielectric strength, self-amalgamating	Joint insulation in MV/HV cables
Composite Kits	Combined tubing + tape systems	Railway signal cable termination
Specialty Types	Chemical-resistant, low-temperature variants	Offshore oil platform cables

3. Structure and Composition

Typical construction includes:

Base material: Silicone rubber or EPDM (Ethylene Propylene Diene Monomer) with nano-fillers
Adhesive layer: Pressure-sensitive rubber-based compound
Outer jacket: Removable PET liner for contamination protection
Reinforcement: Braided fiberglass or polymer mesh (for mechanical strength)

4. Key Technical Parameters

Parameter	Value Range	Importance
Shrink Ratio	150-400%	Determines sealing effectiveness
Operating Temp.	-55 C to +135 C	Environmental adaptability
Dielectric Strength	15-30 kV/mm	Electrical safety margin
Tensile Strength	8-18 MPa	Mechanical durability
Recovery Force	0.5-2.5 N/cm	Sealing integrity maintenance

5. Application Fields

Power Distribution: Underground cable joints, transformer terminations
Telecommunications: Fiber optic cable closures
Rail Transport: High-vibration cable routing in locomotives
Petrochemical: Explosion-proof cable seals in hazardous areas
Renewable Energy: Wind turbine cable entry systems

6. Leading Manufacturers
