Raychem Termination Kits
Raychem Termination Kits are specialized products used to terminate and insulate the ends of electrical cables, particularly in medium- and high-voltage applications. These kits are essential for ensuring the safe and reliable operation of power distribution systems.
Key Components and Functions:
Heat Shrink Tubing: The kits typically include heat shrink tubing that, when heated, shrinks to fit tightly around the cable, providing insulation and protection against environmental factors such as moisture and contaminants.
Stress Control Tubes: These components help to manage the electrical stress at the point where the cable insulation ends and the termination begins, reducing the risk of electrical breakdown.
Insulating Materials: Raychem kits often include various insulating materials to cover and protect the cable’s exposed conductors, ensuring proper insulation and preventing electrical shorts.
Conductive Materials: These may be used to establish an electrical connection with the cable’s shield or armor, helping to maintain the integrity of the grounding system.
Sealing Materials: To prevent moisture ingress, which can lead to corrosion and insulation failure, the kits include sealing materials like mastic and adhesive-lined heat shrink.
Lugs and Connectors: These are used to make the physical and electrical connection between the cable conductors and the terminals of electrical equipment.
Applications:
Medium-Voltage Termination Kits: Used for cables typically rated from 6 kV to 36 kV, these kits are used in substations, transformers, switchgear, and other electrical installations.
High-Voltage Termination Kits: These are for cables rated above 36 kV and are used in high-voltage transmission systems and large industrial installations.
Benefits:
Reliability: Raychem’s products are known for their durability and long-term performance, even in harsh environments.
Ease of Installation: The kits are designed for easy installation, often requiring only standard tools and minimal training.
Safety: By providing effective insulation and stress control, these kits help to prevent electrical failures that could lead to outages or hazard
Usage Process:
- Preparation: The cable is stripped, and the conductors are prepared according to the manufacturer’s instructions.
- Installation of Stress Control: The stress control tubes and other materials are applied to manage electrical stress.
- Application of Insulation: Insulating components are applied to protect the conductors.
- Sealing and Shrinking: Heat shrink tubing and sealing materials are used to protect the cable termination from moisture and contamination.
- Connection: Lugs and connectors are attached to connect the cable to the electrical system.
Raychem Termination Kits are widely used in power distribution networks, industrial installations, and utilities due to their proven performance and ease of use.
