Description

A Raychem 33 kV End Termination Kit is a medium-voltage cable accessory used to safely terminate 33 kV power cables at equipment such as switchgear, transformers, or overhead lines. It provides proper electrical insulation, stress control, sealing, and mechanical protection at the cable end.

These kits typically use heat-shrink technology, where polymer tubes shrink tightly around the cable when heated, forming a secure insulation and environmental seal.

Raychem termination kits are widely used in power distribution networks, substations, and industrial installations for reliable connection of XLPE or similar insulated cables up to 33 kV.

Main Components of the Kit :

A typical 33 kV Raychem termination kit includes:

• Heat-shrink insulation tubes
• Stress control tubes
• Anti-tracking tubes (especially for outdoor type)
• Cable lugs / connectors
• Earthing braid or copper tape
• Sealing and insulating mastic
• Breakout boots
• Installation instructions

These components ensure proper insulation grading and environmental protection at the cable termination point.

Types : Raychem 33 kV termination kits are mainly available as:

1. Indoor Termination Kit
   • Used inside switchgear rooms or control panels
   • No exposure to sunlight or pollution
2. Outdoor Termination Kit
   • Used for overhead connections or outdoor switchyards
   • Includes anti-tracking and UV-resistant insulation

Key Features :

• High dielectric strength insulation
• Excellent moisture and weather resistance
• UV and chemical resistance
• Long service life (often 25+ years)
• Easy installation using heat-shrink method
• Suitable for single-core and three-core XLPE cables
• Complies with standards like IEC 60502-4, IEEE 48, IS 13573

Applications :

Raychem 33 kV termination kits are used in:

• Electrical substations
• Power distribution systems
• Industrial plants
• Renewable energy systems
• Utility transmission networks
• Transformer and switchgear connections

Working Principle :

1. Cable insulation is stripped to the required dimensions.
2. Stress-control tubes are installed to manage electrical stress.
3. Heat-shrink insulation tubes are applied with a gas torch.
4. Cable lug is crimped and connected to equipment.
5. Outer tubes shrink to seal the termination from moisture and environment.
