Unarmoured 3cores Medium Voltage Power Cables 12/20KV ,XLPE
Insulated(XLPE/CU/XLPE/LSZH/NYY)Nominal Section:35~400mm²
Applications:
The three core cables are designed for distribution of electrical
power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and
frequency 50Hz. 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(3.6/6KV to 18/30KV)
Noted:Three Core Cables to BS 6622/BS 7835/IEC 60502/VDE 0276

Cable Construction:
medium voltage cables are manufactured using the monosil process.
We provide the highly specialized plant, state-of-the-art research
facilities and meticulous quality control procedures that are
required for the manufacturing of PVC insulated cables for use up
to 6KV and XLPE/EPR insulated cables for use at voltages up to 35
KV. The materials are all kept in cleanliness-controlled conditions
throughout the production process in order to ensure the absolute
homogeneity of the finished insulation materials.
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.
