玻璃钢电力保护管主要用于强电和高压电缆的敷设，因是强电敷设深度要求为1200mm。埋在地下的强电和高压电缆是会产生热量的，要排出这些热量就只有通过保护导管，所以玻璃钢电力保护管为了更好的达到散热效果会在生产管道时加入石英沙，以形成空气流通层，但是加入石英沙的同时也就意为着降低了管材的强度。强电敷设采用的是深度敷设对保护管本身的强度要求就会低很多，所以即便加入石英砂使管材的强度低了很多，也能满足电力管网敷设要求。

The GFRP power protection pipe is mainly used for the laying of strong power and high voltage cable, because it is the requirement of the depth of 1200mm for the strong electric laying. In the underground high voltage and high voltage cable can generate heat, the heat is to be discharged only by protecting the catheter, so glass steel power protection tube in order to better achieve the cooling effect will be added in the production of quartz sand pipe, to form a layer of air circulation, but adding quartz sand also means reduced pipe strength. The laying of the strong electricity is deep laid, and the strength requirement of the protective tube itself will be much lower. Therefore, even if the quartz sand is added, the strength of the pipe will be much lower, and it can also meet the laying requirements of the electric power network.
