技术领域
本实用新型涉及电线电缆技术领域，具体为220kV交联聚乙烯绝缘金属套电力电缆。
背景技术
目前常用的额定电压为220kV高压电缆，最外部设置金属铠装，但是金属套的机械强度不高，并且金属护套的防腐蚀能力也差，并且电缆内部短路，电流较大造成金属护套损坏。
实用新型内容
针对上述技术问题，本实用新型提供一种220kV交联聚乙烯绝缘金属套电力电缆，提高电缆的多项性能。具体的技术方案为：
220kV交联聚乙烯绝缘金属套电力电缆，从内到外依次包括：导体、导体屏蔽层、交联聚乙烯绝缘层、绝缘屏蔽层、半导电缓冲阻水带、铜丝缠绕层、半导电阻水带层、皱纹铝合金套、非金属护套、半导电层。
进一步的，所述的非金属护套从内到外依次包括绝缘级瓷化胶防火材料层、外绝缘层。
优选的，所述导体的截面形状为紧压圆形、分割导体或型线同心绞合导体。
皱纹铝合金套材料为铝合金，强度、防腐能力远大于普通铝。
铜丝缠绕层增加了短路电流时的截面。
本实用新型提供的220kV交联聚乙烯绝缘金属套电力电缆，不仅可以增加金属套的机械强度，提高金属护套的防腐蚀能力，而且还可以提高金属套所承载短路电流的容量，保证了电缆在发生短路时的安全问题。陶瓷化防火材料在外部发生火灾时，仍有一定的防火性能，确保电缆在通电。该结构的高压电缆适用于大型发电站等大容量输电线路使用。
附图说明
图1是本实用新型的剖面结构示意图。
具体实施方式
结合附图说明本实用新型的具体实施方式。
如图1所示，220kV交联聚乙烯绝缘金属套电力电缆，从内到外依次包括：导体1、导体屏蔽层2、交联聚乙烯绝缘层3、绝缘屏蔽层4、半导电缓冲阻水带5、铜丝缠绕层6、半导电阻水带层7、皱纹铝合金套8、非金属护套、半导电层11。
皱纹铝合金套8为在半导电阻水带层7外径向包裹的皱纹铝合金套。
所述的非金属护套从内到外依次包括绝缘级瓷化胶防火材料层9、外绝缘层10。外绝缘层10为绝缘级聚氯乙烯、中密度聚乙烯或高密度聚乙烯材料制造而成。
所述导体1的截面形状为紧压圆形、分割导体或型线同心绞合导体。
铜丝缠绕层增加了短路电流时的截面，皱纹铝合金套8一起，提高所承载短路电流的容量保证了电缆在发生短路时的安全问题。
