Description

风力发电机专用电缆护套
技术领域
本发明属于电线电缆的护套技术领域，特指一种风力发电机专用电缆护套。
背景技术
风能作为一种清洁的可再生能源，越来越受到世界各国的重视。其蕴量巨大，全球的风能约为2.74×109MW，其中可利用的风能为2×107MW，比地球上可开发利用的水能总量还要大10倍。中国风能储量很大、分布面广，仅陆地上的风能总储量约32.26亿千瓦，其中可开发利用的风能储量约2.53亿千瓦，而海上的风能储量约7.5亿千瓦，总计约10亿千瓦，约相当于50座三峡电站的装置容量，按照国家规划，未来15年，全国风力发电装机容量将达到2000万至3000万千瓦。从近两年全球的风力发电的增长情况看，在未来几年的风力发电机可能以50％以上的速度增长，这些情况显示，风力发电有一个大力发展和推广的空间，与风电工程配套使用的风力发电机专用电缆存在着巨大的市场需求，特别是沿海岛屿、交通不便的边远山区、地广人稀的草原牧场、沙漠边疆，更是有巨大的发展空间。
风能发电工程在露天环境下进行，风机使用年限又要求很长，且要求电缆在低温环境下随风机频繁旋转，这就要求电缆护套在低温条件下具有稳定性好，抗开裂性能优，安全性能高，使电缆使用寿命周期长，护套所用的材料要求柔软性能好，耐高温、低温效果好等优点，普通的丁腈PVC护套材料所含的无机材料较多，而橡胶含量较少，造成断裂伸长率变小，容流指数低，从而使普通的丁腈PVC护套材料抗开裂性能较差，一般在-25℃的条件下就有开裂现象，稳定性不好，安全性能低，使电缆的使用寿命周期短。
发明内容
本发明的目的是提供一种稳定性好，抗开裂性能优，安全性能高，使电缆使用寿命周期长的风力发电机专用护套。
风力发电机专用电缆护套，由如下重量份数的原料制备而成：
上述的稳定剂是由氰脲酸铅，上述的润滑剂是硬脂酸钡，上述的增塑剂是癸二酸二辛酯(DOS)，上述的填充剂是高岭土，上述的促进剂是硬脂酸铅。
本发明相比现有技术突出的优点是：本发明由聚氯乙烯树脂和丁腈橡胶作为主要成分，改善了拉伸强度，定伸应力，抗撕裂性，耐热性和耐燃性，提高了耐油，耐燃油和耐化学药品性能，改善了压延加工性能，还提高了储存稳定性，使得本发明具有耐臭氧和耐天候老化性能，断裂伸长率变大，容流指数高，稳定性好，抗开裂性能优，一般在-50℃的条件下不会出现开裂现象，安全性能高，电缆的使用寿命周期长。
具体实施方式
本发明的实施例1、实施例2的原料及组成成分的重量份数见下表：
序号 原料名称 实施例1 实施例2
聚氯乙烯树脂 100 100
丁腈橡胶 13 18
增塑剂 55 50
活性碳酸钙 30 35
稳定剂 6.5 7.5
润滑剂 0.4 0.6
填充剂 2 2.8
促进剂 0.5 0.6
由实施例1和实施例2可以看出，本发明由聚氯乙烯树脂和丁腈橡胶作为主要成分，改善了拉伸强度，定伸应力，抗撕裂性，耐热性和耐燃性，提高了耐油，耐燃油和耐化学药品性能，改善了压延加工性能，还提高了储存稳定性，使得本发明具有耐臭氧和耐天候老化性能，断裂伸长率变大，容流指数高，稳定性好，抗开裂性能优，一般在-50℃的条件下不会出现开裂现象，安全性能高，电缆的使用寿命周期长。
