Abstract

本实用新型的目的是提供一种防冻抗拉电线，其特征在于，由内至外依次为导体、绝缘内护套、外护套，外护套与绝缘内护套之间设有热塑性聚氢酪内衬层；导体为至少三条铜丝绞合而成。本实用新型的防冻抗拉电线采用热塑性聚氢酪内衬层设计，由于设置了热塑性聚氢酪内衬层，具有良好的耐寒性，可以实现电线自身保温，不易结冰，减少了因结冰带来的电线损坏；多条铜丝绞合提高了电线的抗拉强度。

Description

防冻抗拉电线
技术领域
本实用新型涉及一种电缆，具体是涉及一种防冻抗拉电线。
背景技术
随着电力工业、数据通信业、城市轨道交通业等的发展，各行各业对电缆的要求越来越高，在使用中，不仅要避免电缆受机械损伤、绝缘损伤、绝缘老化变质等，还要在低温条件下使用，即耐低温。现有的输电线路没有防冻设备，一到冬天，下雪或下雨容易在输电线路上结冰，压断电线，造成大面积停电。有时甚至造成短路引起火灾，且在低温条件下易断裂，极不安全。
实用新型内容
本实用新型的目的是克服上述技术问题，提供一种防冻抗拉电线。
具体技术方案如下：
一种防冻抗拉电线，其特征在于，由内至外依次为导体、绝缘内护套、外护套，外护套与绝缘内护套之间设有热塑性聚氢酪内衬层；导体为至少三条铜丝绞合而成。
本实用新型的防冻抗拉电线采用热塑性聚氢酪内衬层设计，由于设置了热塑性聚氢酪内衬层，具有良好的耐寒性，可以实现电线自身保温，不易结冰，减少了因结冰带来的电线损坏；多条铜丝绞合提高了电线的抗拉强度。
附图说明
图1为本实用新型的结构示意图；
图中：1-导体，2-绝缘内护套，3-热塑性聚氢酪内衬层，4-外护套。
具体实施方式
下面结合附图对本实用新型做进一步描述。
一种防冻抗拉电线，由内至外依次为导体1、绝缘内护套2、外护套4，外护套4与绝缘内护套2之间设有热塑性聚氢酪内衬层3；导体为至少三条铜丝绞合而成。
最后，还需要注意的是，以上列举的仅是本实用新型的具体实施例子，显然，本实用新型不限于以上实施例子，还可以有许多变形。本领域的普通技术人员能从本实用新型公开的内容直接导出或联想到的所有变形，均应认为是本实用新型的保护范围。
