Cables Properties
Special features which we can offer for MV cables:
l Watertight construction (both radial and longitudinal).
l Lead sheath available for options.
l Resistant to heavy vibration.
l Available in long delivery lengths to reduce number of joints.
l Copper or aluminum conductor up to 630mm².
l Metallic sheath and radial moisture barrier made of copper wire or tape.
l Different options for outer PE jackets (LDPE, MDPE & HDPE).
l Different options for LSF, LSZH & FRPVC, being anti-termite or UV resistant as per BS 7835, IEC 60332 etc.
l Strippable insulation screen.
l Metallic screen made of multiple layers of copper tapes or a combination of copper wires and tapes to increase the earth fault current carrying capacity.
l Increased armour conductivity by insertion of hard drawn copper wires in armour.
Product features:
Conductors
Either aluminium or copper conductors are used. Conductors up to 630mm² will be circular, compacted & stranded and shall comply with IEC 60228 class 2. 630mm² conductor will be circular stranded type on which a layer of semi-conducting tape will be applied.
Insulation
This will be an extruded layer of XLPE applied over conductor screen under triple extrusion process along with conductor screen and insulation screen.
Insulation Screen
This will be a layer of semi-conducting crosslinkable compound which will be applied by triple extrusion process over the insulation.
Over Sheath
An extruded layer is applied over the armour in case of armoured cables and over laid up cores in case of unarmoured cables. Outer sheath material can be either PVC, PE, HDPE or MDPE. our
medium voltage cables are normally supplied with red PVC over sheaths complying with BS 6622 or IEC 60502. Other colors may be provided to suit a range of installation considerations such as the effect of UV radiations and differing soil compositions. Anti-termite formulations can also be supplied in addition to graphite-coated over sheaths where on-site testing of the sheath is required.
Fire Performance on Cable Sheaths:
Cables can also be supplied with special flame retardant PVC over sheaths to comply with the IEC 60332 standard. We can also supply cables with Low Smoke Halogen Free (LSZH) sheaths according to BS 7211 and BS 6724 standards or other equivalent international standards.
