1. The products are mainly complying with IEC 62067 standard, also
can be produced according to OEM requirements and other standards,
such as bs standard, DIN standard, ASTM standard, etc.
Voltage grade is up to 220kv, cross-section area can be up to 2500
sqmm (copper or aluminiun conductor). Conductor long-time operating
temperature is 90 degrees. In short circuit, conductor highest
temperature should be not more than 250 degrees.
2. Brief Construction:
Single core
Copper or aluminium conductor
Conductor screen
XLPE insulation
Insulation screen
Aluminium laminated sheath,Corrugation Aluminum sheath, Lead sheath
or Copper corrugated sheath
PVC or PE sheath
3. Laying conditions: For lyaing under ground with large different
altitude, be able to bear external machanical force and moderate
pulling force
4. High Voltage Power Cables MANUFACTURING FEATURES
Conductor
The conductor shall be round compact stranded copper or aluminum
wires. The resistance of each conductor at 20ºC shall be in
accordance with IEC 60228 standard. The surface of the conductor
shall be clean and free from any foreign particles, which may
contaminate the insulation or cause high electrical field stress in
the conductor screen.
Extrusion of conductor screen, insulation and insulation screen
shall be by single pass, triple extrusion method. Conductor screen,
XLPE main insulation and insulation screen shall be produced by
triple extrusion and dry curing.
Conductor screen shall consist of semi-conducting tapes applied
over the conductor and a continuous layer of extruded
semiconducting XLPE compound covering the entire surface area of
the conductor and firmly bonded to the inner surface of the
insulation.
The insulation shall be XLPE and shall be applied by extrusion and
cross-linked to form a compact and homogeneous layer in accordance
with the Standards specified. The insulation material shall be of
Super Clean polyethylene mixture suitable for cross-linking (XLPE).
Insulation screen shall consist of a layer of extruded
non-strippable semi-conducting thermosetting compound.
After triple extrusion, the insulated cores shall be degassed to
remove the by-product in the core from the cross-linking process.
Bedding
Semi-conducting water-blocking tapes (swellable tapes) over the
insulation screen shall be applied to prevent longitudinal water
penetration between insulation screening and metallic sheath. The
swellable tape shall cover the entire surface area of the
insulation screen.
Metallic sheath
Aluminium laminated sheath,Corrugation Aluminum sheath, Lead sheath
or Copper corrugated sheath shall be applied over the
semi-conducting water blocking tape to accommodate the required
radical water tightness and protect the insulation core.
Outer sheath
The outer-sheath shall be of an extruded layer of black color
PVC.It shall be highly chemical resistance and withstand the
mechanical force during fabrication, transit,installation and
operation.
Outer conductive layer
A coating of Graphite shall be applied over the over sheath to
carry out D.C. Voltage Test.
