《建筑工人》1997年第7期的《进户线滴水弯》一文中提到,在雨季,进户线的配电盘下往往出现一滩积水。积水出现的原因是由于进户线与户外架空裸线绑扎处,因为毛细管和虹吸作用,雨水沿着橡皮线表面和线芯之间的间隙渗入。且因室外的进户杆上的横担通常高约6米,进户线离地约2.7米,而配电盘距地约1.4米,由于高低差,雨水经橡皮线由接头处压出,产生滴水成滩现象。过去解决这个问题时,往往采用在弯线底部将导线绝缘层剥开一个横向口子的方
In the article “The Construction Worker” (1997) in the article “Drawing Draw Curves for Home Lines,” it was mentioned that in the rainy season, a pool of water often appears under the switchboard of the incoming line. The reason for the accumulation of stagnant water is due to the tying of the entrance line to the bare overhead line. Because of the capillary and siphon effect, rain water seeps along the gap between the surface of the rubber line and the core. And because the outdoor crossbar on the entrance rod is usually about 6 meters high, the entrance line is about 2.7 meters away from the ground, and the switchboard is about 1.4 meters away from the ground. Due to the difference in height, rain is pushed out of the joint by the rubber line, causing dripping. Beach phenomenon. In the past, this problem was solved by stripping the wire insulation at the bottom of the bend line with a lateral opening.
