19/33kv xlpe insulated copper wire copper tape screened pvc
sheathed aluminum cable 3Cx95sqmm
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.
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.
