The cable cover is made of a variety of materials, and the steel fiber is heavy and not convenient for construction or maintenance, but it is very cheap. Resin and polymer-based composite materials have poor temperature resistance, high brittleness in winter, easy expansion in summer, poor application effect, short service life, and higher price than steel fiber concrete.
The cable cover mainly uses unsaturated resin, chopped glass fiber, filament, one or more fillers and reinforced skeleton.
The cable cover has stable performance, high temperature resistance, acid and alkali resistance, compression resistance, bending resistance, impact resistance, and strong flame retardancy. The price is relatively higher than that of steel fiber concrete, recycled resin and polymer-based composite materials, but the service life and product performance are higher. The cable cover is made of polymer composite material.
The cable cover is formed at high temperature, has no secondary use value, and has the characteristics of natural anti-theft function.
The weight of the cable cover of the same specification is only one third of that of the cast iron cover, which brings great convenience to installation, inspection and maintenance, and can produce products of various specifications and colors according to customer requirements, even for urban use Management and beautification. The cable cover has a long service life, is not afraid of acid and alkali corrosion, does not rust, is electrically insulated, and is wear-resistant.
