CONSTRUCTION

2.1 Conductor

Plain, annealed electrolytic copper conductors, circular stranded, or sectoral stranded.

2.2 Insulation

XLPE thermosetting material..

2.3 Assembly

Insulated conductors are laid up, filled where necessary with non-hygroscopic material and covered with an extruded thickness of thermoplastic material.

2.4 Armour

Galvanized round wires completely covering the assembly of cores.

2.5 Sheath

PVC based thermoplastic material.

TEST AT WORKS according to IEC 60502-1 armored

 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

                        Armour:             according to IEC 60502-1                       Parag.  16.7
