| 而通信行业的电缆、光缆都属于弱电，不会产生热量，所以敷设深度也要低一些，一般设计要求在700mm(实际施工中一般只有300-500)，埋设浅保护管所承受的冲击就会更大，通信行业对管道的强度和冲击韧性要求都高于电力行业，所以通信行业所用的保护管是不能采用加有大量石英砂的玻璃钢管。 Cables and optical cables in the telecommunication industry are weak electricity and do not generate heat, so the laying depth is also lower. The general design requirements are 700 mm (in actual construction, only 300-500 generally). The impact of buried shallow protective pipes will be greater. The strength and impact toughness requirements of pipelines in the telecommunication industry are higher than those in the power industry, so the protective pipes used in the telecommunication industry can not be adopted. Fiberglass pipes with large quantities of quartz sand are used. |
