Popular Science Lesson: Thermal Shrinkable Cable Joints 2025-12-04 Heat-shrinkable cable joints are cable joints manufactured using a complete set of heat-shrinkable cable accessories. These accessories are made from rubber and plastic materials using special processes and include heat-shrinkable insulating tubes, heat-shrinkable semi-conductive tubes, heat-shrinkable oil-resistant tubes, heat-shrinkable sheathing tubes, heat-shrinkable branch tubes, and heat-shrinkable rain skirts. Due to their relatively simple manufacturing process, they are widely used for the termination and intermediate joints of various rubber and plastic cables with different voltage ratings. Their internal structure is similar to that of wrapped cable joints.

They are typically made of silicone rubber or ethylene/propylene rubber, allowing for natural shrinkage. Normally, a spiral plastic support strip is used to maintain the inner diameter and shape of the accessory before use. During field installation, simply slip the accessory onto the cable joint (terminal or intermediate point), pull out the plastic support strip, and the rubber accessory will tightly shrink onto the corresponding part of the cable. The entire process requires no heating, simplifying the installation process. Currently, cold shrink accessories are mainly used on cables with voltage levels of 35kV and below, as shown in the figure.

Popular Science Lesson: Wrapped Cable Joint 2025-12-02 The insulation and semi-conductive shielding layers of the wrapped cable joint are both made of self-adhesive tape with rubber as the base material. It is mainly suitable for the termination and intermediate joints of medium and low voltage extruded insulated cables of 35kV and below.

These accessories are made of silicone rubber or EPDM rubber and consist of a series of attachments that provide the necessary shape for the cable joint. During field installation, simply slip the accessories over the cable insulation, simplifying the installation process. Because prefabricated cable accessories must correspond one-to-one with the cable's outer diameter, there are many specifications and models available. Currently, prefabricated cable accessories are used on cables of various voltage levels. The internal structure of the cable joint is basically the same as that of a cold-shrink cable joint.
Popular Science Lesson: Cast Cable Joints 2025-11-26 Cable joints utilize either a metal sheath (iron, lead, aluminum, etc.) or a non-metallic sheath (nylon, plastic, etc.), with an insulating casting agent (such as epoxy resin, asphalt, cable oil, etc.) poured inside to form the joint. This type of joint is commonly used in oil-impregnated paper-insulated power cables. The figure shows a schematic diagram of a 6-35KV oil-impregnated paper-insulated cable intermediate joint. The joint sheath uses a lead sleeve. To ensure good contact between the lead sleeve and the cable's lead sheath, the ground wires at both ends of the cable should be welded to the lead sleeve last.

The failure rate of this type of intermediate connector is relatively high and it is relatively difficult to measure.
