近年来杭州地区批量输电线路由架空导线改成了入地电缆，如何选取和应用大量支撑和固定电力电缆的支架成为一个突出的问题。通过传统金属电缆支架和复合材料电缆支架技术、经济参数的对比，充分显示了复合材料制成电缆支架的优越性，着重介绍了螺栓固定式复合电缆支架的安装与使用情况。%In recent years, a batch of transmission lines in Hangzhou are changed from overhead type to un-derground cables. The selection and use of a large amount of holders for supporting and fixing power cables obviously become a problem. By comparing technical and economical parameters of traditional metal holders with those of composite holders, composite holders are obviously superior to the metal ones. The paper mainly introduces installation and use of bolt-fixed composite cable holder.
