1) The power equipment cable shall not be laid in the same trench with the pipeline conveying class A, B and C liquid, combustible gas and power.

2）配電線路不得穿越通風管道內腔或敷設在通風管道外壁上，穿金屬管保護的配電線路可緊貼通過管道外壁敷設。

2) The distribution line shall not pass through the inner cavity of the ventilation pipe or be laid on the outer wall of the ventilation pipe. The distribution line protected by metal pipe can be laid close to the outer wall of the pipe.

3）配電線路敷設在有可炮灰物的悶頂內時，應采取穿金屬管等防火保護措施；敷設在有可燃物的吊頂內時，宜采取穿金屬管、采用封閉式金屬線槽或難燃材料的塑料管等防火保護措施。

3) When the distribution line is laid in the closed roof with gunpowder, it should take fire protection measures such as metal pipe; when it is laid in the ceiling with combustible materials, it should take fire protection measures such as metal pipe, closed metal trunking or plastic pipe of flame-retardant materials.
                              

4）開關、插座和照明燈具靠近可燃物時，應采取隔熱、散熱等防炎保護措施。哈爾濱電氣成套設備鹵鎢燈和額定功率不小于100W的白熾燈光的吸頂燈、槽燈、嵌入式燈，其引入線應采用瓷管、礦棉等不燃材料作隔勢保護。超過60W的白熾燈、鹵鎢燈、金屬鹵燈光源、熒光高壓汞燈（包手電感鎮流器）等，不應直接安裝在可燃裝修材料或可燃構件上。

4) When switches, sockets and lighting fixtures are close to combustibles, anti-inflammatory protection measures such as heat insulation and heat dissipation shall be taken. The lead-in wires of halogen tungsten lamps, ceiling lamps, trough lamps and embedded lamps with rated power not less than 100W of incandescent lamps of Harbin Electric complete equipment shall be protected by incombustible materials such as porcelain tube and mineral wool. Incandescent lamps, halogen tungsten lamps, metal halide lamp light sources, fluorescent high-pressure mercury lamps (including manual inductive ballasts) with power over 60W shall not be directly installed on combustible decoration materials or combustible components.
