电杆质量包括强度、安全度与外观、尺寸两大部分。前者体现电杆的抗荷能力,即级别,属内在质量,后者则属外在质量,反映其耐久性。二者相辅相成,缺一不可。倘若,单有级别很高的电杆,而忽视了外观缺陷的存在,则必然是强度减弱,寿命缩短。具有某种外观缺陷的电杆,长期处于露之中运行,经受风吹雨打、曝晒骤冷等恶 Pole quality includes strength, safety, appearance and size. The former embodies the resistance of the pole, that is, the level, is an intrinsic quality, and the latter is an external quality, reflecting its durability. The two complement each other and are indispensable. If there is a pole with a very high level and neglecting the appearance defects, it must be weakened and the lifespan shortened. Poles with a certain appearance defect are exposed for a long time and exposed to wind, rain, and sun exposure.
