1.superior flame retardant
2.electric insulation
3.acid and alkali resistance
4.convenient transportation

Features:

1. advanced process, used full automatic CNC spiral winding machine, product could be manufactured by one pass, quality is stable and reliable.

2. clean and sanitary installation, concision and convenience, shorten the construction duration greatly, lower down the installation cost, could avoid many traffic problems caused by road excavation.

3.FRP with granule cable duct has high density, smooth inside surface, easily threading without injuring cable.

4. good water proof, could work in wet or water etc bad environment for long time.

5. superior cold resistance, hot resistance, and fire retardants. Property of duct can’t be changed during -50-130 centigrade, could be used for a long time.

6. high thermal conductivity is good for cable cooling.

7. good isolation, puncture strength is stronger than 3.5KV/MM without eddy current loss.

8. acid & alkali resistance, radiation proof, anti-aging, longer working life etc advantages, could be used for 50 years without maintenance.

Usage:

1. used as protective duct in electricity and communication duct laying, especially in the environment of cable passing through traffic main mouth, river, bridge etc special environment, could show its easy construction, high density etc advantages, be widely used in electricity power, communication, traffic, airport building etc basic facilities field.

2. has a unique result when used in very cold, high temperature and high content of acid & alkali environment.

3.ring-bending rigidity is up to 5000----10000N/m2, could be widely used as protective duct of expressway and lag of horizontal crossing.
