19/33kv cu/sc/xlpe/sc/cws/pvc medinum voltage power cable 3x70, 3x95, 3x120sqmm
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.
