[Accessories of a product ] [Other products ]

 

    DBS fibre glass quartz cable ducts are on the basis of original fibre glass reinforced plastic cable ducts, Adopting advanced craft and technology, a new generation succeeding in developing optimizes the products, which has more scientific and reasonable structure, more steady and reliable quality and higher automatic than ordinary fibre glass reinforced plastic cable duct. Better performance and lower cost make it more attractive in the market.

 
DBS Specification type

1 - grade code

 

N- normal type: Suitable for many kinds of occasions, such as greenbelt, pavement,etc., Free of adding the concrete seal to strengthen!

 

R- reinforced type: Suitable for some fields that bear the pressure such as the runway covering light backfill soil, Free of adding the concrete seal to strengthen.

 

E- exceed type: Suitable for special occasions, such as abominable heavy pressure,etc. frequently, Free of adding the concrete seal to strengthen!

2 - internal diameter
3 – thickness

( ) - classification of fibre glass

 

E- fibre glass yarn with no alkali
C- fibre glass yarn with mid-alkali

Example: DBS-R 150*6( E) internal diameter  mark is 150 mm ,thickness mark is 6 mm , reinforced type fibre glass quartz cable duct.

Superior performance of DBS fibre glass quartz cable duct

· 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.
