What are cable joints used for?
Cable joints are elements of all cable equipment. They can be used to make connections, as well as branches and even cable terminations. Importantly, all kinds of mechanical or electrical properties are retained. The parameters remain unchanged. They can be used to make cable connections in electrical networks, e.g. low voltage. It is also worth knowing that joints are suitable for connecting cables, as well as polymer wires made of PVC, PE or EPR. A cable joint is used to connect power cables. They can be used to connect two or even more cables. It is also worth knowing that models are available made in heat shrink, cold shrink and even encapsulated technology. Cable joints, depending on the type, are used to connect single-core or multi-core cables.
Types of cable joints
Cable joints can have a very diverse design. Here we can list the joints:
- pass-through (used to connect cables of the same type)
- transitional (used to connect sections of different types of cables)
There are different types of cable joints:
- resin - they are made from a two-part 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 joints. Its installation is very easy and quick. It does not require the use of any specialist tools. Thanks to the use of the resin mixture, the joint adapts to the shape of the joint. It is also resistant to sunlight, chemical agents and will work well in difficult conditions.
- tape - they are used for repairing wires, as well as connecting them. In these models, the connection of wires is made using pressed connectors. The cable insulation has a self-bonding tape, and the screens on the wire, which can be repaired using 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 joints gain such great durability thanks to the tinned copper sleeve and springs, the pressure of which 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 moisture-resistant and fire-resistant.
Cable joints are repairable and also insulate the place that is being repaired. It does not lose its electrical properties. They not only branch, but also connect and insulate cables, and also protect them from leaks of the saturant, which is in the paper insulation. In addition, they provide protection against moisture or mechanical damage. Thanks to their low price, you can really cheaply and quickly repair various cables.

It is worth attention heat shrink sleeve12/20 kV Cellpack . It is made of a three-core paper-insulated cable. Thanks to its 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.
Onninen Wholesale also offers a product which is the RAYCHEM transition cable joint . It is used for paper-insulated cables, both with regular and non-draining saturants. It has high mechanical strength, but also impact strength.
A cable through-joint is also suitable for repairs. Its installation is extremely easy and fast. It uses a heat shrink technique. It is used to connect cables of various designs. The three-layer main insulation is also worth noting.
