Quality Cables

We understand the importance of quality cables within our industry. Cables should be built to last and consistently perform the task for which they were built – otherwise, the customer loses valuable time and money.

At CDC, we have long believed that quality is the most important element of cable design, whether that’s honing our manufacturing process or carefully choosing the materials we use.

This is reflected in the accreditation our organisation has been awarded over the years. We are independently audited on a regular basis, and each time we pass with flying colours; our management system, for example, has been accredited to ISO 9001:2015 standard, a reflection on the efficiency of our processes.

Our cables are subject to stringent testing, with comprehensive inspections carried out on every single product we produce.

We provide certificates of conformity with all of the cables we manufacture and the materials we use are fully traceable, so you can be certain you’re receiving a quality, reliable product.

Physical and visual testing

The dimensional stability of our cables is one of the key indicators of quality, and ensures that we are compliant with the brief set out by the customer.

To measure the dimensional stability of our cables, we strip down each layer individually and measure all of the variables – measurements are carried out using micrometers, vernier calipers and the shadow graph to ensure full compliance.

This process also confirms that the surface finish, strip-ability and flexibility of the cable conform to requirements.

Electrical testing

Low resisitivity is key to the performance of an electrical cable, enabling the efficient carrying of electricity from one point to another.

To measure the continuity and resisitivity of a cable, we utilise an industry standard Volt-Ohm meter.
Should the cable pass this test, we carry out integrity testing using a Meg-Ohm meter. If the cable passes this test, we then prepare the cable for despatch.

RoHS Certification of Compliance

CDC is fully compliant with EU Directive 2002/95/EC, which restricts the use of 6 substances – lead, mercury, PBB (Polybrominated Biphenyls), PBDE (PolybrominatedDiphenyl Ethers), Hexavelent Chromium and Cadmium – in the manufacture of specified electrical equipment.

The suppliers of the wire, cable and other components we use in our cables are also ROHS compliant.
