(三)铝导线头的连接 (1)目前的照明工程有许多是采用铝芯电线。铝线的机械强度差,易氧化。按有关规定,铝线和铝线连接时,严禁用绞接法和绑接法,通常可用压接。10mm~2及以下的单股小截面铝芯电线的连接,需采用单股小截面压接钳。这种压接钳,可压接2.5、4、6及10mm~2四种 (3) Connection of aluminum wire leads (1) Many current lighting projects use aluminum core wires. The aluminum wire has poor mechanical strength and is prone to oxidation. According to the relevant regulations, when connecting aluminum wire and aluminum wire, it is strictly prohibited to use splicing method and tying method, usually crimping can be used. For connection of single-stranded small-section aluminum core wires of 10mm~2 or less, single-strand small-section crimping pliers are required. This crimping pliers can be crimped to 2.5, 4, 6 and 10mm~2
