Kabelknytningar

Kabelknytningar, or cable connections, refer to the methods and arrangements used to join electrical cables to other cables, devices, or terminations. Proper cable connections ensure electrical continuity, mechanical stability, insulation, shielding, and environmental protection. They are used in power distribution, control systems, telecommunications, and many other applications.

Types of cable connections include splices, terminations, connectors, and junctions. Splices join two conductors end-to-end, for example butt splices or inline splices, and may be soldered, crimped, or heat-shrunk. Terminations prepare a conductor for connection to a component, such as lug terminals, ferrules, or screw terminals on terminal blocks. Connectors provide removable joins, including automotive, industrial, and circular or rectangular multi-pin connectors. Junctions consolidate multiple cables within enclosures, often using junction boxes and cable glands to maintain protection ratings.

Materials and methods vary by application but generally involve conductor materials such as copper or aluminum, insulation like PVC or XLPE, and protective features such as shielding or moisture seals. Connectors and splices require appropriate tools and procedures to ensure proper crimping, soldering, or sealing. In high-reliability systems, impedance control, shielding integrity, and environmental sealing are critical.

Standards and safety considerations emphasize correct sizing, insulation, strain relief, and protection against moisture, dust, and mechanical stress. Installation and testing typically include continuity checks, insulation resistance tests, and inspections for correct torque, labeling, and routing.
