新型绝缘产品在京沪电气化铁道上的应用

Application of New Insulation Product in Beijing-Shanghai Electrified Railway

在既有电气化铁道改造工程中,跨线建筑物及下承式桥成为制约电气化实施的决定性因素,尤其是对于那些无法替代或改造的设施,必须研究出特殊的绝缘加强及防护措施。本文介绍了京沪电气化铁道改造工程中南京长江大桥所采用的新型绝缘产品,提出在既有线电气化改造中采用绝缘加强防护方案,以解决净空不足的问题。

During reconstruction of existing electrified railway, the buildings passing over the line and the through bridges are the constraints for the implementation of railway electrification, the special insulation and protection measures shall be taken especially for those facilities which is un-replaced or reconstructed. The article introduces the insulation products adopted in Yangtze river bridge of Nanjing during Beijing-Shanghai electrified railway reconstruction, puts forward the plan for strengthening insulation and protection so as to solve the problem of less clearance.
