Abstract

煤井用高阻燃抗干扰防爆测控电缆，涉及一种电缆，其中最外层为辐照交联型耐油弹性体聚烯烃外护套，外护套内设有铜丝编织层，编织层内设有PE隔离绕包层，绕包层内设有至少两根的绞合线芯。本发明的最外层护套材料为使其燃烧性能达到GB/T18380.3-2001中的A类标准要求，采用聚烯烃材料作为骨架材料，因煤井用高阻燃抗干扰防爆测控电缆使用于特定的环境中，电缆护套要有耐油、耐酸、耐热的特性外，而且还要具有好的物理机械性能，最重要的是电缆燃烧时满足成束燃烧性能，因此选择了氧指数在36以上的辐照交联型耐油弹性体聚烯烃护套料，各种性能都达到了设计要求。

Description

煤井用高阻燃抗干扰防爆测控电缆
技术领域
本发明涉及一种电缆，特别涉及一种煤井用高阻燃抗干扰防爆测控电缆。
背景技术
随着科技的日益发展，各种高科技含量检测设施越来越被广泛应用。因此同样需要科技含量高的测控电缆与之配套，而现有电缆在阻燃性能屏蔽上存在不足。
发明内容
发明目的：本发明是为了克服现有技术的不足，提供一种成束阻燃性能好、屏蔽抑制系数低，具有高阻燃防爆测控电缆。
技术方案：一种高阻燃防爆测控电缆，其中最外层为辐照交联型耐油弹性体聚烯烃外护套，外护套内设有铜丝编织层，编织层内设有PE隔离绕包层，绕包层内设有至少两根的绞合线芯。
绞合线芯由设在外层的105℃高阻燃聚氯乙烯绝缘料层和设置在内层的无氧铜丝导体组成。
本发明的最外层护套材料为使其燃烧性能达到GB/T18380.3-2001中的A类标准要求，采用聚烯烃材料作为骨架材料，因煤井用高阻燃抗干扰防爆测控电缆使用于特定的环境中，电缆护套要有耐油、耐酸、耐热的特性外，而且还要具有好的物理机械性能，最重要的是电缆燃烧时满足成束燃烧性能，因此选择了氧指数在36以上的辐照交联型耐油弹性体聚烯烃护套料，各种性能都达到了设计要求。
本发明成束燃烧性能好，抗干扰性能强，具有高阻燃防爆性，能适应各种测控设施的需要。
附图说明
附图为本发明的一种结构示意图。
具体实施方式
如附图所示：一种煤井用高阻燃抗干扰防爆测控电缆，其中最外层为辐照交联耐油弹性体聚烯烃外护套1，外护套1内设有铜丝编织层2，编织层2内设有PE隔离绕包层3，绕包层3内设有至少两根的绞合线芯，绞合线芯由设在外层的105℃高阻燃聚氯乙烯绝缘料层4和设置在内层的无氧铜丝导体5组成。
