Custom-Made Cable | Bespoke Cable Manufacturing to Client Specification

Custom-made and bespoke cables manufactured to client specification. Any conductor configuration, insulation, shielding, sheath, and jacket material. For special-purpose industrial, marine, subsea, and aerospace applications.

Custom-Made Cables — Bespoke Cable Manufacturing to Specification

When no standard product meets the application requirements, we design and manufacture custom cables to client specification. Our engineering team works from client-supplied specifications — or develops the specification in consultation with the customer based on the application environment, mechanical duties, electrical requirements, and relevant standards — to produce a cable that is precisely matched to the application rather than adapted from a standard product.

Custom cables are manufactured for quantities from small prototype runs to full production volumes, with full traceability documentation, test certificates, and factory acceptance test records available for each production lot. Lead times and minimum order quantities depend on the specification complexity and material lead times.


Custom Cable Capabilities

  • Any conductor configuration: single core, multicore, twisted pairs, triaxial, coaxial
  • Conductor materials: copper, tinned copper, nickel-plated copper, aluminium
  • Insulation: PVC, PE, PTFE, silicone, XLPE, EPR, rubber
  • Shielding: foil, braid, spiral, combination — any configuration
  • Sheath: PVC, PUR, rubber, LSZH, TPE, silicone, PE
  • Armour: steel wire, steel tape, aluminium, Kevlar
  • Jacket colour: any RAL colour on request
  • Marking: metre marking, client logo, part number, custom print

Our Custom Cable Development Process

Specification Development

We work with your engineering team to translate application requirements into a cable specification — identifying the critical parameters (voltage, current, temperature, mechanical duty, environmental exposure) and selecting materials that satisfy all requirements with appropriate margins.

Prototype and Validation

For critical applications, we produce a prototype run for customer evaluation and testing before committing to full production tooling. This process identifies any application-specific issues before they become production problems.

Production and Documentation

Production cables are manufactured with full quality control and test records. Electrical tests (insulation resistance, conductor continuity, voltage withstand) are performed on every production drum, with results recorded on the drum certificate.

Custom-Made Cable | Bespoke Cable Manufacturing to Client Specification

The perception of a custom cable means many things to different people.

 It could simply mean that an alternative jacket material or possibly that a different colour or conductor colours are required. 

It could also mean that you have a requirement for a highly complex solution where a cable with very specific materials and configurations are required. 

We want to dispel the myth that a custom cable generally equals high cost and long delivery dates. Whether your looking for a simple material alternative, 

alternative core colours to an existing cable type or require a complete design from first principles then we have a solution for you.



What is a Custom Cable?
Custom cables are used wherever an off the shelf solution or industry standard cable type simply won’t suffice. 



They are manufactured with a specific application in mind, utilising unique components and designs to fulfil the demands of an operating environment.
we have over 20 years’ experience in designing, manufacturing and supplying custom cables to a vast range of industry sectors where an off the shelf solution simply will not suffice. 
Unique combinations of data, power and video type hybrid cables can be specified. 


These products can be designed either from first principles or using existing off the shelf products allowing you to select varying material configurations alongside solid technical advice. 

You can determine the appropriate level of screening that is required on either individual elements or around the cable as a whole. 

You can also specify the outer jacket working environment and select a material type that is appropriate both from an operating temperature and mechanical characteristics point of view.

 We are here to advise on what options are available to you which makes the process as easy, efficient and cost effective as possible.
