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.
