Cable termination heads are essential components used to provide a safe, reliable, and effective termination point for electrical cables, particularly in high-voltage and medium-voltage applications. They are designed to connect the cable conductors to electrical equipment like transformers, switchgear, and other systems, while ensuring the safety of the equipment and personnel.
Key Features of Cable Terminations (Cable Termination Heads)
Insulation Protection
Cable termination heads are designed with high-quality insulation materials such as elastomeric rubber, silicone, or polymer to prevent electrical faults due to short circuits or electrical leakage.
They help maintain electrical safety by isolating the conductors from external conductive surfaces.
Stress Control
These terminations are engineered to control the electrical stress that typically occurs at the cable's end due to the high voltage. Stress control materials like semi-conductive tapes or heat shrink materials are used to ensure uniform stress distribution across the cable's termination.
Moisture Sealing
Many termination heads are designed with sealing components to protect against moisture ingress. This ensures the safety and durability of the connection, particularly in outdoor or harsh environmental conditions.
Mechanical Strength
Cable termination heads provide mechanical protection to prevent physical damage during handling and installation. They often have robust, durable casings to withstand mechanical impacts and vibrations.
Heat Shrink or Cold Shrink Technology
Some terminations use heat shrink technology, which involves applying heat to shrink the casing over the cable, ensuring a tight and sealed fit.
Cold shrink technology is a more recent advancement, providing a similar seal without the need for heat, making it safer for applications where heat may be a concern.
Voltage Rating
Cable terminations are rated for specific voltage levels, ranging from low voltage (LV) to high voltage (HV) systems. The design of the termination is directly influenced by the voltage rating of the cable and the requirements of the application.
Durability
Depending on the application, cable termination heads can be designed to be resistant to chemicals, UV light, and extreme temperatures, ensuring a long service life in different environments.
