0.6/1kV 35mm Copper Core XLPE Insulated Power Cable
Product description and application
A power cable is a component of one or more electrical conductors,
usually fixed together with the entire sheath. This component is
used to transmit power. Power cables can be installed in buildings
as permanent wiring, buried in the ground, walking overhead or
bare.
Used for transmission and distribution in 0.6/1kV to 8.7/15kV
transmission and distribution systems. It is usually used in
electric power, construction, mining, metallurgy, petrochemical
industry and communications and other fields.

Application:
This product is suitable for power transmission and distribution
with AC rated voltage 0.6/1kv and working frequency 50Hz.
Low-voltage power cables are used for power transmission and
distribution in 1kV power transmission and distribution systems. It
is widely used in electric power, mining, construction, metallurgy,
petrochemical and communication fields, and completely replaces
oil-immersed paper-insulated power cables.
XLPE insulated power cables XLPE insulated power cables have more
advantages than paper insulated cables and PVC insulated cables.
The cross-linked polyethylene cable has high electrical strength,
mechanical strength, high aging resistance, chemical corrosion
resistance, environmental stress, simple structure, convenient use,
and can be used at high temperatures for a long time. It can be
placed without a drop limit.
Advantages of XLPE cable: XLPE cable has a higher long-term working
temperature and larger rated current, and under the same
environment, the size (normal cross section) of XLPE cable may be 1
or 2 smaller than that of PVC cable. These not only improve the
quality and performance of the product, but also reduce the
production cost of the cable. Armored cable
The steel tape armored cable can enhance the mechanical properties
of the cable, and the cable can withstand external mechanical
pressure.
Steel belt armor/steel foil armor, steel wire armor/steel wire
armor/SWA. Steel tape armored cable model: VV22, VV23, VLV22,
VLV23, YJ V22, YJV23, YJLV22, YJLV23, ZR-VV22, NH-VV2 2, WDZ-YJV22,
WDZ-YJV23, WDZ-YJY22
