一、绝缘导线和电缆的型号,应按工作电压和使用环境要求选择,其导体的截面应满足:导体的允许载流量不应小于线路的负荷计算电流,以防线路由于长期过负荷而发生短路引起火灾。 二、配线时应尽量避免导线有接头;导线接头处应采用压接和焊接;穿在管内导线,在任何情况下都不能有接头,必要时尽可能将接头放在接线盒或灯头盒内,以防接头接触不良造成打火或短路,引起火灾。 First, the type of insulated conductors and cables shall be selected according to the working voltage and the requirements of the use environment. The conductor cross-section shall meet the following: The allowable ampacity of the conductor shall not be less than the calculated load current of the line to prevent short circuit due to long-term overload. Causes fire. Second, the wiring should be avoided when the wire connector; wire joints should be crimped and welded; wear the wire in the tube, in any case can not have a connector, if necessary, the connector as possible in the junction box or lamp box , In order to prevent poor contact caused by fire or short circuit, causing fire.
