IEC 60502-1 Cables

600/1000V, PVC 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

The conductors shall be either of Class 1 or Class 2 of plain or metal-coated annealed copper or of plain

aluminium or aluminium alloy, or of Class 5 of plain or metal-coated copper in accordance with IEC 60228.

Insulation

PVC Insulation material and thickness shall be as per IEC 60502-1, PVC material shall be Type A as per IEC

60502-1.

Colour Code

Colour Code (1) :

1Core:  Red or Black

Colour Code (2) :

1Core: Brown or Blue

Other colours can be manufactured upon request.

Assembly/Inner Covering

The inner coverings may be extruded or lapped. For cables with circular cores, except cables with more than five

cores, a lapped inner covering shall be permitted only if the interstices between the cores are substantially filled.

A suitable binder is permitted before application of an extruded inner covering. The materials used for inner

coverings and fillers shall be suitable for the operating temperature of the cable and compatible with the

insulating material.For halogen free cables, the inner covering and fillers shall also be halogen free compound.

Lead Sheath

lead or lead alloy and shall be applied as a reasonably tight-fitting seamless tube.

Outer Sheath

Outer sheath shall be of extruded PVC Type ST1/ST2 as per IEC 60502-1, Polyethylene type ST3/ST7, Halogen

free compound ST8, Polychloroprene, chlorosulfonated polyethylene or similar polymers, type SE1 are also

available on request.
