Description

A Raychem High Voltage (HV) Heat Shrink Termination is a cable termination system used to safely terminate high-voltage polymeric power cables (typically XLPE or EPR insulated). It provides electrical stress control, insulation, environmental sealing, and mechanical protection at the cable end. Raychem heat-shrink technology is widely used in utility, industrial, renewable energy, and substation applications.

Key Features :

• Voltage ratings up to 72.5 kV for standard heat-shrink termination systems.
• Suitable for indoor and outdoor installations.
• Heat-shrink stress control sleeves ensure uniform electric field distribution.
• Non-tracking outer insulation for polluted and outdoor environments.
• Moisture-proof and corrosion-resistant sealing.
• Compatible with compression and mechanical cable lugs.
• Lightweight design with no oil or compound filling required.
• Complies with IEC 60840 for high-voltage cable accessories.

Typical Applications :

• Power transmission and distribution networks
• Electrical substations
• Industrial plants
• Wind and solar power installations
• Underground cable systems
• Utilities and infrastructure projects

Typical Kit Components :

A Raychem HV heat shrink termination kit generally includes:

• Stress control tubes
• Anti-tracking insulation tubes
• Rain sheds (for outdoor terminations)
• Breakout and sealing components
• Mastic and sealing materials
• Installation instructions
• Accessories for earthing and shielding, depending on the cable type

Installation Overview :

1. Prepare the cable according to the specified dimensions.
2. Install the stress control tube over the insulation.
3. Crimp the cable lug.
4. Heat-shrink the insulation tubing.
5. Install rain sheds (outdoor type).
6. Apply sealing components and complete earthing connections.
7. Inspect dimensions and clearances before energization.

Proper installation requires controlled heating and adherence to the manufacturer’s instructions to ensure reliable long-term performance.
