IEC 60502-1 Cables

600/1000V, XLPE Insulated and Lead Sheathed Cables according to IEC 60502-1(unarmoured)

Application:

IEC 60502-1 cables are used for electricity supply in low voltage installation system, IEC 60502-1 cables are

suitable for installation in indoors and outdoors, in cable ducts, under ground, in power and switching stations,

local energy distributions, industrial plants, where there is no risk of mechanical damage. The lead sheath brings

an enhanced resistance to aromatic hydrocarbons.

Construction

Conductors:

Conductors shall be Round Stranded (Non-compacted or Compacted) or shaped,

Class 2 as per IEC 60228. For smaller sizes up to and including 4 mm2, Solid Conductors,

Class 1 to IEC 60228 can also be provided based on special request.

Insulation:

XLPE Insulation material and thickness shall be as per IEC 60502-1 rated for 90°C continuos operation.

PVC Insulation material and thickness shall be as per IEC 60502-1 and BS 6346.

PVC material shall be Type A as per IEC 60502-1 or TI1 as per BS 6346.

PVC Insulation material as per SASO 1694 rated for 85°C continuous operation is also available upon special

request.

Assembly / Two, Three or Four insulated conductors are laid-up together with non-hygroscopic fillers Inner

Sheath compatible with the insulation material and the assembly is bedded with an extruded layer of PVC. Lead

Sheath Extruded lead Alloy Type "E" to BS 12548. Thickness of lead shall be as per IEC 60502-1. Cables with

other thickness of Lead Sheath can also be provided based on specific request.

ArmourGalvanized Steel Wires in accordance with IEC 60502-1 or BS 6346 or BS 5467 laid

helically over PVC bedding as per requirement. Galvanized Steel Tapes applied helically over PVC bedding in

accordance with IEC 60502-1

Outer Sheath

Outer sheath shall be of Extruded PVC Type ST2 as per IEC 60502-1 or Type 9 as BS 6346/5467. Special type of

PVC sheathing material such as Fire Retardant PVC, Anti-Termite PVC, Anti-Rodent PVC, Sunlight resistant PVC,

Oil Resistant PVC are available on special request. Also, special sheathing materials such as LLDPE, MDPE, HDPE,

LSF, CPE are available on request.
