Medium Voltage Cable

High quality super clean XLPE insulating compound is used for insulating the cores on ‘Maillefer’ CCV line equipped with online x-ray analyser to maintain the desired thicknesses of insulation and semiconducting layer as per the relevant standards.

Shield consisting of a layer of bonded or strippable, extruded semi-conducting compound applied in tandem over the insulation.

Copper tape / copper wires is helically applied over the cores, of cross section suitable as per the standard or as per the system fault current requirement. Colour marking tape is applied longitudinally below the metallic sheath for core identification.

Separation sheath of ST-2 PVC along with polypropylene [PP] fillers, is provided.

The armour is given for the protection of cable against physical damage. Galvanised round steel wire or galvanised steel tapes are applied helically over bedding as armouring. However, single core cables are armored with Aluminium round wire or Aluminium tape.

The outer sheath shall be of extruded Polyvinyl Chloride (PVC) type ST2 as per IEC 60502-2, Type 9 as per BS 7655 or LSF/LSZH Type LTS1 / ST 8.
Polyethylene outer sheath is used in case the cable requires higher impregnability to moisture. Outer sheath is of generally black/ red colour or as per project requirement.

Outer sheath shall be marked / embossed with Manufacturer name, no of cores, size, Voltage ratings, and year of manufacture, sequential length marking and any other desired marking for better identification at site

Cables with special flame retardant PVC compounds meeting flame test requirements of IEC 60332-3-22, IEC 60332-3-23 or IEC 60332-3-24 are manufactured
as per project requirement.

The cables are supplied on drums manufactured from high quality pine wood or steel. The pine wooden drums are properly seasoned and treated, with minimum painting to make them more eco-friendly. The cable ends are sealed with heat shrinkable end caps, marked with our logo, to avoid any possibility of ingress of water or dirt during transportation and storage as well as any pilferage of the cable.

Each drum is clearly marked with our name and logo, type, size, length, net and gross weight and sequential length marking details. An arrow and suitable instruction is marked on the drum indicating the direction, the drum should be rolled while laying the cable.
