The composite electrical telecom manhole cover have a great demand of electrical industrial. Like cement manhole cover, plastic manhole cover......
With the development of times, composite material become more and more popular.
The composite electrical telecom manhole cover have two different mold:
The first one: SMC electrical telecom manhole cover
SMC: sheet molding compound. SMC special yarns, unsaturated resin, low shrinkage additives, fillers and various additives composition. Long glass fiber and no needs the steel bar to improve the load capacity. excellent electrical properties, corrosion resistance, light weight, and engineering design easy, flexible, etc.
SMC electrical telecom manhole cover
The second one is BMC electrical telecom manhole cover.
BMC: short glass fiber with general toughness. Therefore, reinforcement must be used to enhance the load, and it is molded once through high temperature molding. The quality of BMC material products is affected by many aspects: the difference of steel quality, the grade of short glass fiber material, etc. In order to reduce the cost and price of products, some manufacturers will add sand to the formula. Sand and glass fiber are not integrated, so it is easy to break the internal structure in the use process, which will affect the quality of the product; at the same time, different welding points of steel bars are also easy to break, which will affect the quality. Danger to the social environment.
