12.7/22(24)KV 3Cx240sqmm tripolar medinum voltage power cable
12/20(24)KV xlpe insulated power cable APPLICATIONS:
12.7/22(24)KV 3Cx240sqmm tripolar medinum voltage power cable
12/20(24)KV xlpe insulated power cable are designed for distribution of electrical power with nominal
voltage Uo/U ranging from 6.35/11(12)KV 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), BS 6622, BS 7835 (LSZH Version)
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
This will be an extruded layer of semi-conducting crosslinkable
compound applied under simultaneous triple extrusion process over
the conductor along with the insulation and the insulation screen.
The triple extrusion is a single high precision operation that
eliminates the possibility of any contamination between the layers
which could create irregularities in the electrical field. By
careful material selection and special attention to process
parameters, we produce the insulation screen layers with the
required degree of stripping force as stipulated by the applicable
national or international standard.
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.
Metallic Screen
It will consist of a layer of copper tape applied helically with
overlap over insulation screen. Other combinations of metallic
screens as per customer ’s requirement can also be provided on
request.
Laying-Up
In case of three core cables, the three cores are laid up with
non-hygroscopic fillers like polypropylene(PP) fillers at
interstices and a binder tape is applied with an overlap. These
binder tapes can be of PVC or foamed Polyethylene.
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.
