2. The leakage area of the normal cable cover is 83.3%, which is more than twice that of cast iron. Some defective products have shrunk a lot. Pay special attention to this.
3. The important point is to look at the mechanical strength of the cable cover. The traditional high strength and toughness are much higher than cast iron. It can be used in large-span and heavy-duty environments such as terminals and airports.

According to different materials, cable trench cover plates are divided into ordinary cement cable trench cover plates, composite cable trench cover plates, and FRP cable trench cover plates. Among them, the cable cover is mainly made of cement, supplemented by fine orthopedics, glass fiber, ore, and modifiers, which solves some application problems of cement products, and has the characteristics of light weight, high strength, long service life and easy construction.
