Flame-retardant cable classification: according to the different flame-retardant materials of cables, flame-retardant cables are divided into halogen flame-retardant cables and halogen-free low-smoke flame-retardant cables. Which contain halogen flame retardant cable insulation, sheath, outer sheath and auxiliary material (package belt and filling) in whole or in part by polyethylene (PVC) containing halogen flame retardant material, thus has good flame retardant properties. However, when the cable burns, a large amount of smoke and haloic acid gas will be released. Haloic acid gas is corrosive to the surrounding electrical e When the cable burns, it will cause harm to the surrounding electrical e and rescue personnel, which is not conducive to the fire fighting and rescue work, thus causing serious "secondary hazards". All or part of the insulation layer, protective sleeve, outer protective layer and auxiliary materials (packing belt and filling) of the halogen-free low-smoke flame-retardant cable are adopted

Any cable specified in the UL flame retardant standard UL may be marked with a UL identification, fire rating and approval number if it is tested and verified to meet a certain fire rating.

仪表指示是否与刀开关，断路器对应。母排，线路各连接部位有无过热变色现象。如果在运行中检查仪表盘上三相负荷是否平衡、三相电压是否相同。配电柜和电器里面有无放电声和烧焦的异味。。带灭弧罩的断路器，刀开关三相灭弧罩是否完整无缺。这个很多缺陷应该很多都存在，还是应该引起重视。检查断路器有无过大噪声。9.母排绝缘夹有无损伤和歪斜，母排夹固定螺丝有无松脱。10.配电柜里面设备的表面是否清洁，接地连接是否正常良好。
