Fiberglass ladders were originally developed for electrical utilities but have increasingly gained acceptance for general industry and residential use. Fiberglass now holds a significant market share of industrial ladders and is steadily replacing aluminum and wood in residential ladders.
According to D2/T802-2002 - Standard for Power industry of P.R.C, our company has developed glass fibre reinforced plastic (short for FRP) cable conduit yet; Meanwhile, we have also developed PVC/FRP cable conduit under the requirements stated in Guide to Power Engineering. With such nicer characteristics as insulated, flame-retardant, corrosion-resistance, light, high-intension, both of the two cable conduits are suitable for protecting ground & underground cable in power and communication industry. And it is easy to pull out and replace the faulted cable once it breaks down. Today, the two kinds of cable conduit made in our company have been widely applied in the power, communication and civic engineering and taken the fancy of numerous constructors and engineers.
