600/1000V, XLPE Insulated Cable In Accordance With IEC 60502-1
Application field
These cables are used for power supply in low-voltage installation
systems and are suitable for installation in indoor and outdoor,
cable ducts, underground, power and exchange stations, local energy
distribution, and industrial plants without mechanical damage.
Conductor
The conductor shall be ordinary or metal-coated annealed copper or
ordinary aluminum or aluminum alloy in accordance with IEC 60228
level 1 or 2, or shall be class 5 ordinary or metal-coated copper.
Insulation
The material and thickness of XLPE should meet the requirements of
IEC 60502 or BS 5467, and it is suitable for continuous operation
at 90°C.

Assembly/inner cover
The inner cover can be squeezed or ground. For cables with round
cores, except for cables with more than five cores, the use of
overlapped inner coverings is only allowed when the gap between the
cores has been substantially filled. Before applying the extruded
inner cover layer, it is allowed to use a suitable adhesive. The
material should be compatible with the insulating material, and the
material used for the inner covering and filling layer should be
suitable for the working temperature of the cable and compatible
with the insulating material; for halogen-free cables, the inner
covering and filling layer should also be halogen-free compounds.
Armor
According to IEC 60502-1, aluminum/galvanized steel/steel wire is
spirally wound on the inner cover, and double aluminum/steel tape
and copper/tinned copper wire can also be manufactured according to
requirements.
Outer sheath
The outer sheath should be ST1/ST2 type extruded PVC, ST3/ST7
type polyethylene, halogen-free compound ST8, polychloroprene,
chlorosulfonated polyethylene or similar polymers in accordance
with IEC 60502-1, The SE1 type is also available on request.
Fire performance of cable sheath
The cable can be provided with a special flame-retardant PVC jacket
to meet the flame-retardant test requirements of IEC 60332-3-22,
IEC 60332-3-23 and IEC 60332-3-24, and the halogen-free materials
comply with IEC60754-1 / 2 and IEC 60684 -2.
