TEST AT WORKS GENERALLY TO BS 7835

Routine Tests

- Max. DC conductors resistance at 20°C acc. to BS EN 60228

- High voltage test acc. to BS 7835  parag. 18.6

- Max. partial discharge test  acc. To BS 7835  parag. 18.5

 

Liban Cables will carry out these tests on all the lengths and tests certificates will be provided.

 

Sample Tests

- Check of the build - up and color coding of the cable                                                    

- Check of dimensions                                                  

            Insulation                      :           according to BS 7835     Parag.  19.7

            Separation sheath         :           according to BS 7835     Parag.  19.12

            Armouring                     :           according to BS 7835     Parag.  19.14

            Oversheath                   :           according to BS 7835     Parag.  19.15

 

These tests will be carried out on one length of each size during each inspection .

Tests certificates will be provided by Liban Cables

 

Type Tests
