电缆沟盖板的厚度，其一般是为80毫米。并且，沟盖板和地面表面都是要进行绝缘处理的。
The thickness of cable trench cover is generally 80mm. In addition, the trench cover plate and the ground surface are insulated.
复合电缆沟盖板，它是沟盖板中的一种，其使用也是非常广泛的，其主要特点有：
Composite cable trench cover plate, which is one of the trench cover plates, is also widely used. Its main features are:
(1)因是采用了高分子复合材料，并经过高温模压而成的，所以不能进行二次利用，这样就有了防盗功能了。
(1) it is made of polymer composite materials and molded at high temperature, so it can not be reused, so it has anti-theft function.
(2)其成品重量只有铸铁盖板的三分之一，因此更容易进行安装及维护等，而且颜色多样，以满足不同的要求。
(2) the weight of the finished product is only one third of that of the cast iron cover plate, so it is easier to install and maintain, and the color is diverse to meet different requirements.
(3)其能够耐酸碱的腐蚀，还不会生锈，并且还耐磨。
(3) it can resist the corrosion of acid and alkali, will not rust, and also wear-resistant.
(4)其合缝间隙是比较小的，因此其精度是比较高的。
(4) the seam gap is relatively small, so its accuracy is relatively high.
