Cable and Cable Systems Type Testing
DNV GL provides type testing and certification of medium and high-voltage cable sand cable accessories based on key international and local standards.
Type testing allows you to provide evidence that your cables and cable accessories offer the necessary quality to deliver reliable service over many years.
DNV GL has extensive experience of type testing cable sand accessories and our labs are equipped to handle today’s large conductors. Be sides testing oil and paper insulated cables, we have actively worked on the use and testing of XLPE materials and composites.
Further more, our laboratories can test complete cable systems. By assessing the interaction between cables and accessories, you and your customers can ensure the reareno weak points due to specific components.
Standards covered
You can have your products tested for conformity to a number of international standards including IEC, CENELEC, IEEE and British Standard. If your equire it, we can test for conformity to specific local standards. We can also witness on-site testing.
High-voltage cables and accessories
The IEC 60840 standard applies to cable voltage ratings between 30 kVand 150 kV. It includes a regular type test sequence for cables and a separate sequence for the cable accessories.
IEC 62067 applies to ultra high-voltage cables rated 150 kV and above, manufactured with extruded insulation material. The standardi ncludes a more integrated test sequence for the combination of cables and accessories than required for IEC 60840.
Medium-voltage cables and accessories
The key standard for these products is the IEC 60502 series. IEC 60502-2 covers cables, while IEC 60502-4 covers cableaccessories.
A certified cable must be used when testing cable accessories, however this standard is not considered to be an integrated test sequence for both cables and accessories.
Low-voltage cables and accessories
Various standards apply to low-voltage power cables, the most common being IEC 60502-1.
