Rated Voltage 1k V, 10k V Insulated Aerial (Overhead) Cable

Rated Voltage 1k V, 10k V Insulated Aerial (Overhead) Cable
Properties and functions:
The cable is extruding weatherability XLPE insulation, weatherability
HDPE insulation or black weatherability PVC insulation out of the compacting
copper, and aluminum conductor. With simple construction, good mechanical,
physical and electrical properties, enough safety, it also has good properties of
resistance to tracking, surface discharge resistance, resistance to weathering.
It has smaller laying distance, line length, voltage drop when comparing with bare
wire, especially in reducing accident and ensuring safety of the body. The cable
can be used in city, country, mountain area, forest area, mining area, and
is an all-weather new product of cable.
Properties of application:
1) Rated voltage U/U is divided into two kinds
a) 0.6/1k V
b) 10k V
2) Allowed operating temperature in long-term:
a) PVC insulated cable shall be 70o C
b) HDPE insulated cable shall be 75o C
c) XLPE insulated cable shall be 90o C
3) Max. short-circuit temperature (within 5s):
a) PVC insulated cable shall be 160o C
b) HDPE insulated cable shall be 150o C
c) XLPE insulated cable shall be 250o C
4) The ambient temperature shall not be lower than -20o C during
installation
5) The bending radius of cable:
a) Rated voltage 0.6/1k V and below: outer diameter D <25mm, bending radius
shall not be less than 4D. For outer diameter D?25mm, bending radius shall
not be less than 6D
b) Rated voltage 10k V:
i) Single core cable: 20(D+d)± 5%
ii) Multi-core cable: 15(D+d)±5%
iii) D is actual outer diameter of the cable (mm), d is actual outer diameter
of the conductor (mm)
