TEXT

MEDIUM VOLTAGE XLPE INSULATED POWER CABLES
[19/33kV Copper XLPE Single Core PVC Sheathed]
APPLICATION
Mostly used as feeder electric cable for power
distribution network such as power supply station,
substation, switching system etc. They are suitable
for installation on medium mechanical stress dry,
indoors, outdoors, underground areas.
STANDARDS
Australian/New Zealand - AS/NZS 1429.1:2006.
International - IEC 60228, IEC 60502, IEC 60986.
CONSTRUCTION
Phase Conductor: Plain annealed copper Class 2
compact stranded.
Phase Core: Triple head extrusion - semiconductive,
thermosetting conductor shield,
XLPE (cross-linked polyethylene)
insulation and bonded semi conductive insulation
screen, all dry nitrogen cured.
Metallic Screen: Solid bare annealed copper
wires uniformly spaced around the cable provides
high conductivity for faulty current as earth wires.
(Plain annealed copper wire has a minimum
diameter of 0.85 mm) and a counter helix copper
tape (0.1x10mm).
Sheath: UV resistant heavy duty polyvinyl
chloride (V-90).
33000 volts, XLPE insulation, HD screen, extruded
overlaying PVC sheath

For fault durations other than one second, divide the appropriate given value by the square root of the required time (in seconds)
Screen fault ratings are based on an initial temperature of 80°C and a final temperature of 250°C.
Conductor fault ratings are based on an initial temperature of 90°C and a final temperature of 250°C.
LIGHT DUTY SCREEN DESIGN
- It corresponds to a fault rating equal to the conductor fault rating, but not higher than 2.7kA for 1 second.
HE
AVY DUTY SCREEN DESIGN
- It corresponds to a fault rating equal to the conductor fault rating, but not higher than 13.1kA for 1 second
and not exceeding the conductor rating
