What are Cable Joints?

Cable joints play a crucial role in maintaining the continuity of electrical cables over long distances by connecting them, allowing the transmission of electricity. These joints must fit precisely and be durable enough to withstand various factors such as adverse weather conditions, current carrying capacity, voltage drop, and material compatibility.

Different types of cable joints exist based on the following factors:

Voltage: The voltage determines whether the cable joints need to be designed for high, medium, or low voltage levels. It is essential for the voltage level of the joint to match that of the cable. If the joint's capacity is lower than that of the cable, it would be inadequate to handle the high current and voltage demands.

Insulation: For the cable joint to operate properly, the cable's insulation must be compatible with the joint's. Cable joints can be either cold or heat shrinkable, depending on the cable's purpose and insulation type.

Cores: Cables may have single or multiple insulated cores. Cable joints should have the same number of cores as the cables they connect.

Structure: The way in which cables need to be connected determines the type of cable joint to be used. For example, a straight-through joint is used when two cables need to be connected at a single point. If branching is required, appropriate branch cable connectors are utilized. Cable joints can have different structures such as straight-through, T-shaped, Y-shaped, pot-ended, or with indoor or outdoor terminations.

We offer a variety of cable joints, including heat shrinkable cable joints, cold shrinkable cable joints, pre-moulded cable joints, heat shrinkable cable terminations, cold shrinkable cable terminations, pre-moulded cable terminations, and screened separable connectors.

Our range includes armoured and unarmoured heat shrink cable joints for capacities up to 72.5kV. We also provide cold shrink cable straight joints suitable for 1- and 3-core polymeric insulated cables up to 36kV. Additionally, our pre-moulded straight through joints are ideal for polymeric insulated cables up to 36kV.

For cable terminations, we offer heat shrink options capable of managing loads from 1kV to 72.5kV. Our cold shrink cable terminations are suitable for 1- and 3-core polymeric insulated cables up to 36kV. Furthermore, our pre-moulded cable terminations (push on/slip-on) are designed for safe use with polymeric insulated cables up to 36kV.
