What are cable joints used for?
Cable joints are elements of the entire cable equipment. Thanks to them, you can make connections, branches and even cable terminations. Importantly, all kinds of mechanical and electrical properties are preserved. The parameters remain unchanged. Thanks to them, you can make cable connections in electrical networks, e.g. low voltage. It is also worth knowing that the joints are suitable for connecting cables and polymer conduits made of PVC, PE or EPR. The cable joint is used to connect power cables. They can be used to connect two or even more cables. You should also know that there are models available using heat-shrinkable, cold-shrinkable and even poured technology. Depending on the type, cable joints are used to connect single-core or multi-core cables.
Types of cable joints
Cable joints can have a very diverse design. We can replace the muffs here:
- pass-through (used to connect cables of the same type)
- transitional (used to connect sections of various types of cables)
We distinguish various types of cable joints:
- resin - made of a two-piece mold. They consist of polyurethane resin and insulating tape.
Thanks to these materials, effective insulation and sealing can be achieved. The resin cable joint perfectly protects the connectors. Its installation is very easy and quick. It does not require the use of any specialized tools. Thanks to the use of a resin mixture, the sleeve adapts to the shape of the joint. It is also resistant to solar radiation and chemical agents and works well in difficult conditions. - tape - they are used to repair cables and connect them. In these models, the wires are connected using press connectors. The cable insulation has a self-bonding tape, and the screens are on the wire, which can be repaired with conductive tape.
- cold shrink - have really good technical parameters. They provide a durable connection even in very difficult working conditions and at a temperature of 90 degrees Celsius. The couplers are so durable due to the tinned copper sleeve and springs whose pressure force is constant. The outer shell is covered with cold shrink tubing. In this way, the joints are additionally resistant to moisture.
- heat shrinkable - they are used for armored cables, as well as plastic or screened cables. They have cross-linked polyolefins. You also need to know that they are resistant to moisture and fireproof.
Cable joints are repairable and also insulate the area being repaired. It does not lose its electrical properties. They not only branch, but also connect and insulate cables, and also protect them against leaks of the filler contained in the paper insulation. In addition, they provide protection against moisture and mechanical damage. Thanks to their low price, you can repair various cables really cheaply and quickly.

It deserves attention 
heat-shrinkable sleeve 12/20 kV Cellpack . It is made of a three-core cable with paper insulation. Thanks to the strong insulating layer, it can be used both indoors and outdoors. It is also worth paying attention to its voltage range, which is from 12 to 20 kV.
The Onninen wholesaler also offers a product called the RAYCHEM transitional cable joint . It is used for cables with paper insulation, both with regular and non-dripping material. It has high mechanical and impact strength.
A pass-through cable joint will also be useful for repairs. Its installation is extremely easy and quick. Heat shrink technique is used. It is used to connect cables of various designs. The three-layer main insulation is also noteworthy.
