·
Adopting advanced craft ,shaping onetime in the
programme-controlled twine machine , more steady
and reliable than before.
·Having
high stiffness, high intensity ,to the same
thickness ducts ,the intensity index is 1.5 to 2
times of the ordinary glass steel tubes .
Reinforced type DBS cable ducts can be used
buried directly in the runway, free of pouring the
concrete for protection.
·
Resistance to the corrosion of chemistry ,having
long performance lifespan.
·
Having good insulating ability,
puncture intensity up to more than 3.5 KV/MM,
there is
no loss by vortex ,suitable laying the single core
cable.
·
Adopting the new technology of inserting quartz
sand to improve the cold-resistant, heat
resistance of the products . The products can be
used in the temperature from - 30 ℃ to 130 ℃ for a
long time ,and the performance of the duct is not
influenced .
·Smooth
interior walls, slope both join end 45°, insert
the cable lightly, and will not shave the cable.
·
Easy to install and construct .The product is
light, only one people can lift, two people can
install on the spot, so as to shorten the cycle of
constructing greatly, reduce the install cost,
prevent the road expose so long that influence the
traffic.
·
The cost is low, because of adopting the new
technology, give full play to the characteristic
with good tensile strength of the fibre, the same
intensity to be designed, it is more rational to
use the material.
