The utility model discloses a cold resistant anti rodent power cable, including two inner alloy conductor and a plurality of outer conductors, the two inner alloy conductor and a plurality of outer conductor alloy were coated with silicone rubber outer insulation wire core, outer layer within the insulated wire core, inner insulation wire with lateral extrusion molding silicon rubber elastic layer, silicon rubber elastic layer on the underside of a symmetric aramid belt, the number of peripheral root of insulated wire core are uniformly distributed in the silicon rubber elastic layer composed of a cable core, a cable core is arranged outside the winding layer, a winding layer outside the anti rodent cold resistant NBR sheathed layer, coating. The utility model has the advantages of reasonable structure design, wire extrusion molding in the elastic insulating layer through the cable, which is subjected to external pressure, between the inner conductor and the outer conductor alloy alloy has a buffer effect to reduce the phenomenon of a broken core, guarantee the power and communication unobstructed.
【技术实现步骤摘要】
—种耐寒防鼠蚁电力电缆
:本技术涉及电力电缆,尤其涉及一种耐寒防鼠蚁电力电缆。
技术介绍
:电线电缆聚氯乙烯(PVC)、聚乙烯(PE)等塑料护套材料,在使用中除了受氧、热、光、力、化学侵蚀等环境的破坏作用外,还会受到白蚁、老鼠或野兔等生物的食蚀伤害,从而引起停电事故、通信中断,引起短路甚至引发火灾。对于电缆防鼠蚁的控制电缆经常由于受到外界挤压及拉伸导致电缆导体受损,弓丨起停电事故、通讯中断,给企业等带来重大损失。
技术实现思路
:为了弥补现有技术的缺陷,本技术的目的是提供一种耐寒防鼠蚁电力电缆,结构设计合理,提高了电缆的抗挤压性能及抗拉伸性能。本技术的技术方案如下:耐寒防鼠蚁电力电缆,包括两根内合金导体、数根外合金导体,其特征在于:所述的两根内合金导体、数根外合金导 体外侧均分别包裹有硅橡胶绝缘层构成内绝缘线芯、外绝缘线芯,所述的内绝缘线芯外侧挤塑成型有硅橡胶弹性层,硅橡胶弹性层上下侧对称设有芳纶带,所述的数根外绝缘线芯均匀分布在硅橡胶弹性层的外周共同构成缆芯,缆芯外设有绕包层,绕包层外设有防鼠蚁耐寒丁腈护套层、防腐涂层,防腐涂层的厚度不小于0.75mm0所述的耐 ...
