8.7/15kv cu/sc/xlpe/sc/cws/lszh medinum voltage power cable
3x150sqmm xlpe insulated power cable
APPLICATIONS:
Medium voltage power cable is usually for static application in
ground, within and outside facilities, outdoor, in cable canals, in
water, in conditions where cables are not exposed to heavier
mechanical stress and tensile strain. They are suitable for
installation mostly in power supply stations, indoors and in cable
ducts, outdoors, underground and in water as well as for
installation on cable trays for industries, switchboards and power
stations.
STANDARD:
IEC 60502 Part 2(3.6/6( 7.2) kv, 10kv, 11kv, 15kv, 33kv,35kv and so
on)
Cable Construction
We adopt highly specialized plant, state-of-the-art research
facilities and meticulous quality control procedures that are
required for the manufacturing of xlpe insulated cables for use up
to 6KV and XLPE insulated cables for use at voltages up to 35 KV.
Conductors
Either aluminium or copper conductors are used. Conductors will be
circular, compacted & stranded and shall comply with IEC 60228
class 2.
Conductor Screen
Semi-conductor
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.
Armour type: Galvanized steel wires (SWA)or Galvanized steel
tape(STA)

Laying-Up
Polypropylene strings.
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.
PHYSICAL PROPERTIES:
Operating Temperature: up to 90°C
Temperature Range: -5°C ( PVC or LSZH sheath ); -20°C ( PE sheath )
Short Circuit Temperature: 250°C (short circuit duration up to 5 seconds)
Bending Radius: 12 x OD
