Routine Tests

- Max. DC conductors resistance at 20°C acc. to IEC 60228 & IEC 60502-2 parag.16.1& 16.2  

- High voltage test acc. to IEC 60502-2  parag. 16.1& 16.4                                                          

- Max. partial discharge test  at 1.73 Uo acc. to IEC 60502-2  parag.16.1& 16.3  

( The test voltage shall be raised gradually to and held at 2U0 for 10s and than slowly reduced to 1.73U0).  

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