TEST AT WORKS according to IEC 60502-2

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 IEC 60502-2                       Parag.  17.5.2

            Metallic screen  :           according to IEC 60502-2                       Parag.  17.7

            Oversheath       :           according to IEC 60502-2                       Parag.  17.5.3

- Hot Set Test for XLPE insulation according to IEC 60502-2 parag. 17.10

                                                                       

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
