塑料护套线配线,施工方法简单、线路整齐、造价低廉,在照明线路上广泛使用。塑料护套线一般用铝线卡固定,铝线卡规格有0~#～5~#,见表1。塑料护套线有双层塑料保护层,即线芯一层,外面再统包一层,多芯的护套线必须整根敷设,不得分隔成单芯导线敷设。对于同一要求的照明电路,塑料护套线配线和其它方式配线,如瓷夹、槽板和管子配 The plastic sheath line wiring, the construction method is simple, the line is neat, the construction cost is low, and it is widely used on the lighting line. Plastic sheathed wires are generally fixed with aluminum wire cards. Aluminum wire card specifications are 0~#~5~#, see Table 1. The plastic sheathing line has a double layer of plastic protective layer, that is, a layer of core, and then a layer of external coverage. The sheathed multi-core sheathed cable must be laid as a whole and must not be separated into single-core conductors. For the same requirements of the lighting circuit, plastic sheathed wire wiring and other wiring, such as porcelain clips, slotted plates and pipes
