Product Details
3.6/6(7.2)KV, 3.6/6. MV SIngle core Three Cores aluminum conductor Power Cable (Armoured) XLPE Insulated IEC 60502/60228
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:
International: IEC 60502-2, IEC 60228
China: GB/T 12706.2-2008
Other standards such as BS,DIN and ICEA upon request
CONSTRUCTION:
Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound applied on top of a semi-conducting tape. The conductor screen is applied under triple extrusion process over the conductor along with the insulation and the insulation screen. The extruded semi-conducting compound is firmly bonded to the insulation to exclude all air voids and can be easily hand stripped on site. The conductor screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and 3.6/6KV cables
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.
Inner Sheath (Bedding) for Armoured Cables
Extruded layer of PVC or PE is applied over the laid up cores for armoured cables. PVC is normally of grade ST2 and PE of grade ST7 as per IEC 60502 Part 2.
Armouring
In case of armoured cables, the armour is applied helically over inner sheath. For single core cables, it is of aluminium wires and for multicore cables, the armour can be of one among the following options:
a) Galvanized steel wire.
b) Galvanized steel tape.
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.
Cables Properties
Special features which we can offer for MV cables:
l Watertight construction (both radial and longitudinal).
l Lead sheath available for options.
l Resistant to heavy vibration.
l Available in long delivery lengths to reduce number of joints.
l Copper or aluminum conductor up to 630mm².
l Metallic sheath and radial moisture barrier made of copper wire or tape.
l Different options for outer PE jackets (LDPE, MDPE & HDPE).
l Different options for LSF, LSZH & FRPVC, being anti-termite or UV resistant as per BS 7835, IEC 60332 etc.
l Strippable insulation screen.
l Metallic screen made of multiple layers of copper tapes or a combination of copper wires and tapes to increase the earth fault current carrying capacity.
l Increased armour conductivity by insertion of hard drawn copper wires in armour.
