Cable Extrusion

A complete range of plasticized cable compounds is produced in strict adherence to BS 7655, covering all the different types of insulation and sheathing compounds specified by this standard.

A complete range of plasticized cable compounds is produced in strict adherence to BS 7655, covering all the different types of insulation and sheathing compounds specified by this standard.

Careful development of the cable formulations ensures that all compounds exceed the requirements for mechanical and electrical properties, as well as ageing characteristics. Furthermore, the processing qualities have been enhanced to provide high extrusion outputs with constant surface quality.
