insulator top tie
PVC plastic line ties / top ties are intended for use with covered
conductors and vertically-mounted tie top insulators on crossarms
or pole-top-mounted insulators. Line angles of up to 15°can be
accommodated when used with any plastic covered conductor.
We use the all new raw material, not recycling material to make the
product. so it has the following advantages such as UV resistance,
good tensile strength, impact strength and flexural strength etc.
We can make them in black, white as well as grey at present.
Application: voltage to 15kV.
Mechanical: PVC plastic line ties / top ties will develop
unbalanced and lift-off loads equivalent to, or in excess of, a
hand tie over covered conductor.
Insulators: PVC plastic line ties / top ties are used with either
ANSIcompliant polymer or porcelain insulators, such as Φ63mm (C
Neck), Φ73mm (F Neck).
The company focus on development and production of fittings and
conductors for voltage from 110kV to 1000kV. It had supplied around
10 transmission lines for 800kV till 1000kV in domestic. For
oversea market, it had supplied to Vietnam(220kV&500kV),
India(400kV&765kV), Poland(110kV to 400kV), Pakistan,
Bangladesh, Syria, Paraguay, etc.
To ensure quality products, we have accumulated experience in
designing and producing electric power fittings, electric
substation fittings, and ultra-high voltage power transmission
products. Our major products include 500kV heat-resistant power
line fittings, energy-saving power line fittings,
environmentally-friendly power line fittings, and high altitude
line fittings. We also do research and development in related
Over years of development, we have provided line fittings for heavy
snow area, 750kV ultra-high voltage AC line fittings, 800kV
ultra-high voltage DC line fittings, and 1000kV ultra-high voltage
AC line fittings. Our products are designated to be used in
national large power transmission projects, such as The Three
Gorges and west-east power transmission, and are exported to many
foreign countries in the Middle East and Mid and South Asia. Apart
from this, we provide nonstandard and customized products according
to the specific requirements of our clients.
