Description
技术领域 technical field
本实用新型涉及一种电缆，具体是涉及一种防火电线。The utility model relates to a cable, in particular to a fireproof electric wire.
背景技术 Background technique
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，还要防火。With the development of electric power industry, data communication industry, urban rail transit industry, etc., all walks of life have higher and higher requirements for cables. In use, not only to avoid mechanical damage, insulation damage, insulation aging and deterioration of cables, but also Be fireproof.
传统电缆外层多为橡胶制品，起火后燃烧迅速，很快烧至芯部，危害很大。The outer layer of traditional cables is mostly rubber products, which burn quickly after a fire and burn to the core soon, which is very harmful.
实用新型内容 Utility model content
本实用新型的目的是克服上述技术问题，提供一种防火电线。The purpose of the utility model is to overcome the above technical problems and provide a fireproof wire.
具体技术方案如下：The specific technical scheme is as follows:
一种防火电线，其特征在于，由内至外依次为导体、绝缘内护套、外护套，绝缘内护套与导体之间设有石棉纤维隔离层；外护套为低烟无卤阻燃外护套。A fireproof wire, characterized in that, from the inside to the outside, there are conductors, insulating inner sheaths, and outer sheaths, and an asbestos fiber isolation layer is arranged between the insulating inner sheath and the conductor; the outer sheath is a low-smoke, halogen-free resistor. Burn the outer sheath.
本实用新型的防火电线外部采用低烟无卤阻燃技术，内层设置石棉纤维隔离层，具有耐高温的特性，且即使燃烧，由于护套为低烟无卤护套，对人体及周围环境损坏较小。The fire-resistant electric wire of the utility model adopts low-smoke, halogen-free flame-retardant technology on the outside, and an asbestos fiber isolation layer is arranged on the inner layer, which has the characteristics of high temperature resistance. Less damage.
