Leading Cable Extrusion manufacturer in the UK
Cable extrusion also known as cable jacketing, cable sheathing or cable oversheathing is an essential part of the cable manufacturing process, protecting the cable from mechanical damage and environmental hazards.
Appropriate materials are selected by their performance characteristics and the required operating environment. These might include low and high temperature performance, flexibility, resistance to water, oil or specific chemicals, toxicity – free from halogens, fire reaction/performance and smoke emissions.
CDC Ltd utilise a vast range of different materials for cable extrusion and cable jacketing purposes, and use state of the art equipment to provide high quality results.
The type of extrusion utilised and the material selected will depend on your specific operational performance requirements.
Cable extrusion is applied at numerous points in the cable design process, with each layer of extrusion or jacketing carrying out a vital function in the overall performance of the cable.

- Extrusion of existing cables to increase diameter or change material selection
Wire insulation
Insulating the conductors of a cable ensures that electrical current cannot deviate from its intended route. It isolates conductors from other conductors and outside influences, ensuring that the conductor performs unhampered.
The material and thickness of the insulation used on a conductor determines the maximum operating voltage of a cable.
The material used to insulate conductors is determined by the range of temperatures the cable will be exposed to, flexibility, environmental operating conditions and the intended purpose of the cable.
Bedding layers
A bedding layer is a cost-effective ‘filler’ used in certain applications. It can be used to increase the diameter of a cable and improve its overall shape, which is important for non-standard cable designs. Bedding layers can also provide moisture protection and a mechanical barrier between inner and outer conductors.
When an armoured cable (SWA) is manufactured, a bedding layer is usually added to the cable before the application of the amouring layer to provide mechanical protection to the internal conductors.
Final cable extrusion
Cable extrusion gathers all the components of a cable into a compact unit, providing protection against external influences, damage and physical wear. The material used for a cable jacket is determined by the operating environment – such as temperature, exposure to fluids/chemicals as well as the flexibility and mechanical strength required for the cable’s intended application.
Cable jackets are also used for branding purposes when a company’s logo or name can be printed on the side. Cable printing in this example is for aesthetic purposes however it can also be used for health and safety purposes dependent upon the print legend that is specified.
