摘要
矿物绝缘电缆是一种无机材料电缆,抗材料老化优于有机绝缘电缆,很难引发火灾或传播火焰,不会放出烟雾和有害气体。矿物绝缘电缆使用寿命较长,载流量大,且可经受较大的冲击力。但矿物绝缘电缆存在施工难度较大,安装要求较高等缺点。对矿物绝缘电缆与普通塑胶绝缘电缆进行了经济技术比较,分析其在地铁车站应用的可行性。
The mineral insulated cable is the cable of an inorganic material, the anti-aging material is better than the organic insulated cables. It is fire and flame retarded, generating no smoke and hazardous gas. Mineral insulated cables have longer service life, with large current-carrying capacity, and it can withstand a greater impact. The laying for mineral insulated cable is difficult, and installation has higher requirements. Comparing the mineral insulated cables and plastic insulated cables, cost-effective studies and technical analysis are carried out. The feasibility of the application in the metro station is studied.
