TEST AT WORKS FIRE RESISTANT 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

            Oversheath       :           according to IEC 60502-1                       Parag.  16.5.3

 - Hot Set Test for XLPE insulation according to IEC 60502-1                 Parag. 16.9

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

Mechanical characteristics on insulation and sheaths material (tensile strength and elongation at break) in accordance with IEC 60502-1.

Fire Resistance test according to IEC 60331-21 (750۫C for 90 mins) :

            - 500V between conductors

            - 300V between cond. & earth

These tests will be carried out on one length of the order.

Tests certificates will be provided by Liban Cables
