Description

一种单芯防火控制电缆
技术领域：
本实用新型涉及控制电缆，尤其涉及一种单芯防火控制电缆。
背景技术：
目前市场上防火控制电缆的导体外护管采用铜管，电缆导体大，铜管也有增大，受铜管生产的限制，市售的防火电缆尤其是多芯数防火电缆，其截面积比较小，50mm2以上的大截面多芯防火电缆无法生产，另外铜管护套柔软性差，几乎无法弯曲，不变施工，其电缆成本较高；市面上的大截面单芯矿物绝缘电缆，铜管护套只用拉伸方式延长，其能生产的距离较短，最长一般在100米左右，需要多段连接，如果长距离连接，需要中间的接头多，易进水，产品的安全性能差。
实用新型内容：
为了弥补现有技术问题，本实用新型的目的一种单芯防火控制电缆，有效的提高了电缆的防火、阻水性能。
本实用新型的技术方案如下：
单芯防火控制电缆，包括导体，所述的导体外包裹有屏蔽层，其特征在于：所述的屏蔽层外包裹有陶瓷氧化镁内绝缘层，陶瓷氧化镁内绝缘层外套有金属管，金属管外包裹有陶瓷氧化镁外绝缘层，陶瓷氧化镁外绝缘层外绕包有防水层，防水层外挤塑成型有护套层。
所述的单芯防火控制电缆，其特征在于：所述的金属管采用氩弧焊接的不锈钢波纹管。
本实用新型的优点是：
本实用新型结构设计合理，采用双层绝缘层，双层绝缘层均采用陶瓷氧化镁材料提高了电缆的防火性能，此外，电缆在内绝缘层外套装金属管配合防水层提高了电缆的防水性能。
附图说明：
图1为本实用新型的结构示意图。
具体实施方式：
参见图1：
单芯防火控制电缆，包括导体1，导体1外包裹有屏蔽层2，屏蔽层2外包裹有陶瓷氧化镁内绝缘层3，陶瓷氧化镁内绝缘层3外套有金属管4，金属管4外包裹有陶瓷氧化镁外绝缘层5，陶瓷氧化镁外绝缘层5外绕包有防水层6，防水层6外挤塑成型有护套层7。
金属管4采用氩弧焊接的不锈钢波纹管。
