3、 Smoke density shall meet the requirements stipulated in GB/T17651.2, and its light transmittance shall not be less than 60%.
4、Test for the halogen acid gas content shall be in accordance with the stipulation in GB/T17650.2; pH value shall not be less than 4.3; electric conductivity shall not be more than 10μS/mm.
5、Flame-retardant property shall be in accordance with the requirements of bunched flame test stipulated in GB/T18380.3.
1、This kind of product will be non-fire propagating after firing. It has characteristics such as halogen free, low smoke, no toxicity, no corrosion and so on; it is a product of pollution free type.
2、Five-core power cable is suitable to use in three-phase five-wire transmission and distribution power system. Separating the neutral wire from the ground wire thus is available for the stable operation of the system and safety of the operator. Moreover, since the five-core power cable is designed in a special tile form, the cable has many features such as a stable structure, lightweight, small outer diameter and so on.
