What is Cable Termination Kit

A cable termination kit is used in an electrical system to terminate a high or a medium voltage power cable for a further connection. it is normally made of silicone rubber or porcelain; due to its higher insulation level and pollution-resistance, silicon rubber termination kit are more popular.

cable termination kit

a composite cable terminal kit is made of silicone rubber with LSR injection moulding and other mental parts made of aluminum alloy with a high corrosive & aging resistance. routine testing items complying with IEC 60840 & 62067; Terminal kit assembled on a pedestal insulator making feasible of various grounding connections and Pre-mounted modules for a quick installation, engaged with a higher insulation level and pollution-resistance. Durable & renewable hydrophobicity and its transfer; excellent tracking & arc resistance, in case of an acr happening, there is no evolution of toxic gas and the charred remains of something do not provide a path for electrical current to travel through.

Some more technical descriptions about cable termination kit

Cable termination kit should be able to operate safely for a long time and have the same service life as the power cable itself. Good cable termination kit should have the following performance:

  1. excellent connection of the conductor,  the connection resistance is small and stable, able to withstand the impact of fault current; After long-term operation, the contact resistance should not be greater than 1.2 times the resistance of the same length of the cable conductor.
  2. Good insulation performance, The insulation performance of a cable termination kit should not be lower than that of the cable itself, and the dielectric loss of the insulation materials used should be low. In terms of structure, the sudden changes in the electric field in the cable termination kit should be well handled, and measures should be taken to change the distribution of the electric field. the reason is , When making a cable termination, the shielding layer is removed, changing the original electric field distribution of the cable, which will generate a tangential electric field (along the axial direction of the wire) that is extremely detrimental to insulation. Concentrate the power line with the core wire stripped of the shielding layer towards the shielding layer fracture. So the break of the shielding layer is the most easily penetrated part of the cable.
Standards referring to for a cable termination kit.

Steps for making a cable termination

Cable terminal and middle joint is the weakest point of a cable line, and the quality of its installation is the key to the safe operation of the cable line, which should be given sufficient attention.

1) The cable termination should be moisture-proof during installation and should not be used in rainy, foggy, or windy days. When the average temperature is below 0 ℃, the cable should be pre heated.

2) Ensure the cleanliness of hands, tools, and materials during construction. You should not do anything unrelated during operation (especially not smoking!).

3) The cable termination kit should be pre assembled to check if the specifications are consistent with the cables, if all components are complete, check the date of production, check the packaging (sealing), and prevent errors in peeling and cutting dimensions.

Preparation work for making a cable termination

1. Before laying the cable, the insulation of the cable body should be checked, and the color arrangement should be found on the cable head to avoid crossing the core wires on the middle head of the three core cable (to align the phase sequence).

2. After the cable is laid, a DC withstand voltage test should be conducted on the cable. After the test, the cable head should be sealed to prevent moisture.

3. The middle end cable should have a margin and the position for placing the cable.

4. Peel off the outer sheath

5. Cut off the armoring layer

6. Peel off the inner insulation layer

7. Welding shielding layer grounding wire

8. Copper shielding layer treatment

9. Peel off semi conductive layer

10. Clean the surface of the main insulation layer

11.  Installing a semi conductive tube (terminal head)

12. Install insulation sleeves and wiring terminals
