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

业务素质不高的人员，自然检验技能无法胜任电梯检验工作的安全所需，在工作中常常粗心大意、不按照规程操作，极易引发出各种安全事故。
就要加强检验人员的综合素质培训，组织所有检验人员学习检验中潜在的安全隐患、检验步骤及流程等各种基本知识，提高检验人员业务素质。
还要求检验人员技能考核，参与培训工作且取得资格证，只有达到要求人员才能够独立进行检验工作。
电梯检验属于一项危险性工作，要避免出现安全事故。
Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C.
