我国物理发泡电缆绝缘料生产技术与市场分析

Analysis on insulating material technology and market of physical foamed cable

综述了我国移动通信领域三类发泡绝缘电缆——射频同轴电缆、铁路数字信号电缆、有线电视同轴电缆的市场和技术发展状况,对物理发泡电缆绝缘料用发泡剂和成核剂进行了概述。射频同轴电缆市场用量巨大,前景广阔,但目前国内射频同轴电缆物理发泡绝缘料主要依赖进口,因此,我国应加强射频同轴电缆聚乙烯绝缘材料的国产化以及成核剂母料的国产化,同时加强铁路数字信号电缆发泡材料的研制工作。

The paper reviewed market and technology development of three kind of foamed insulation cables,Radio frequency（RF） coaxial cable, railway figure signal cable; central aerial television（CVTV） coxial cable. The blowing and nucleating agents for physical foamed cable were described. RF coaxial cable has great propect,but the foamed insulation material of the cable mainly depended on importation in China. Therefore,the schedule of home-made RF coaxial cable foamed material and nucleating agent should be accelerated,the railway signal cable foamed material should be researched and produced quickly at the same time.
