电力电缆线路的敷设方式 The method of laying the power cable line (1)直接埋设在地下,这是最通行和最经济的敷设方法。 (1) it is buried directly underground, which is the most common and economical means of laying the means. (2)敷设在电缆沟内,用于多条电缆的敷设。 (2) laying in a cable trench for multiple cables. 电缆沟虽然当时投资比直埋较大,但其便于进行温度监视和采取通风降温措施,改善其散热条件。另外,电缆沟还具有便于电缆检修、新设、更换以及有利于防止外力损伤和故障测寻、修复等优点。 The cable trench, which was larger than the one at the time, was easier to monitor and take cooling measures to improve its cooling conditions. In addition, the cable trench also has the advantage of convenient cable repair, new setting, replacement, and the benefit of preventing the damage of external forces and detecting and repairing. (3)安装在电缆隧道内,当在发电厂或变电站出线电缆很多或并列敷设条数较多(如20~40条以上时)的地区敷设电缆时,应考虑建造电缆隧道。 (3) installed in the cable tunnel, when in power plant or transformer substation for cable article tied for laying a lot or more, such as more than 20 ~ 40 area laying cable, should consider to build the cable tunnel.
