Plain, annealed electrolytic copper conductors, circular stranded, or sectoral stranded, conforming to the applicable requirements of IEC 60228.

2.2 Insulation

XLPE material, conforming to the applicable requirements of IEC 60502-1.

2.3 Assembly

Insulated conductors are laid up, filled where necessary with non-hygroscopic material.

2.4 Sheath

LSZH compound conforming to the applicable requirements of IEC 60502-1.

2.5 TESTS

Conforming to the applicable requirements of IEC 60502-1 either on Raw materials or on finished products.

TEST AT WORKS unarmored multicore

Routine Tests                                                              

 - Max. DC conductors resistance at 20°C acc. to IEC 60228 & IEC 60502-1 parag. 15.1 & 15.2

 - Voltage test acc. to IEC 60502-1  parag. 15.1 & 15.3                                                   

                                                                       

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 60502-1                       Parag.  16.5.2

            Oversheath       :           according to IEC 60502-1                       Parag.  16.5.3

 

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
