Low smoke low Halogen or Halogen-free Wires and Cables
一、產品標準 Standards:
標準：GB/T17650-2008
Intemational: GB/T17650-2008
二、用途 Uses:
本產品適用于電廠、電站、冶金、化工、石油、高層建筑、隧道、地鐵、儀器、儀表等人員密集、空間封閉的場所，當燃燒時要求低鹵或無鹵的場所。
This product is used in enclosed places which are crowded with people,such as power plants,power stations,metallurgy,chemical industry,petroleum,high buildings,tunnels,undergrounds,equipment,and meters.These places demand low halogen or zero halegon when burned.
三、使用特性 Characteristics:
1、 電纜的額定電壓、導體長期允許工作溫度、電纜敷設高溫度等應符合低鹵、無鹵要求相應產品的要求。
2、低煙性能：透光率 小值為60%
低鹵性能：鹵酸氣體釋放量≤100mg/g 無鹵性能：Ph值 ≥4.3 電導率≤10us/mm。
