The thickness of the cable trench cover, which is generally 80 mm. And the groove cover and the ground surface are to be insulated.

Composite cable trench cover, which is a groove cover in the use of its use is also very wide, and its main features are:

(1) because it is the use of polymer composite materials, and after high temperature molding made, so can not be used for the second time, so there is anti-theft function.

(2) its finished weight is only one-third of the cast iron cover, so it is easier to install and maintain, and the color is varied to meet different requirements.

(3) its resistance to acid and alkali corrosion, will not rust, and also wear.

(4) its joint gap is relatively small, so its accuracy is relatively high.
