Description

一种中低压阻燃变频电力电缆
技术领域
本发明属于电力电缆技术领域，特别是一种中压阻燃变频电力电缆。
背景技术
变频电力电缆必须具有较强的耐电压冲击性，能经受变频时的脉冲电压，同时必须具有良好的屏蔽性，能有效消除电磁干扰，降低变频电机噪音，保证系统稳定运行。变频电力电缆的抗电磁波干扰和机械防护性能是影响电缆使用性能的重要因素，而现有的多数变频电缆也无法同时具有优异的抗电磁波能力和较强的抗拉抗压能力。
一般的变频电力电缆内部结构主要采用普通的三根主线芯和一根零线芯构成。但是，由于存在脉冲电压的干扰，即由于在变频系统中变频电源的频率调节范围比较宽，包含了许多高次谐波，幅值也大，这种谐波必然波及到电缆，有可能引起电缆击穿，并且主线芯和零线芯产生的干扰和谐波电压亦不均衡；而且存在电磁波的干扰，即连接变频电源的电缆在运行中产生电磁波，会对周围邻近地区产生电磁干扰，反之外界电磁波也能对变频电缆产生干扰。
发明内容
为克服上述不足，本发明目的是提供一种中压阻燃变频电力电缆，该电缆具备阻燃绝缘性能好和屏蔽功能好等优点。
本发明是通过如下技术方案来实现的：
一种中压阻燃变频电力电缆，其包括护套层，所述护套层由内而外包括三层结构，分别为隔热层、金属编织层以及防护层；所述隔热层外挤包金属编织层，所述金属编织层外挤包防护层；所述隔热层厚度为0.2-0.3mm、金属编织层的厚度为0.1-0.2mm，防护层厚度为2mm；
所述隔热层为双层合成云母带；所述金属编织层由铜丝编织层外绕包铝塑复合膜制备而得；所述防护层为热塑复合材料，其由如下重量份的原料制备而得：
高密度聚乙烯120-200份、低密度聚乙烯70-100份、聚碳酸酯40-70份、乙烯-醋酸乙烯酯共聚物20-30份、聚乙烯蜡10-15份、氢氧化镁7-9份、氢氧化铝7-9份、碳化硅5-7份、癸二酸二辛酯5-7份、炭黑3-5份、钛酸酯交联剂3-5份、硅藻土2-3份、二硫化钼2-3份、四硫化双五亚甲基秋兰姆2-3份、滑石粉 1-2份；
其制备方法包括以下工艺步骤:
按照重量份取各原料备用；将氢氧化镁、氢氧化铝、碳化硅、癸二酸二辛酯、炭黑、钛酸酯交联剂、硅藻土以及二硫化钼，依次添加到高速混合机中1500rpm搅拌5min，然后升温至100℃，保温5min，再加入聚碳酸酯、四硫化双五亚甲基秋兰姆以及滑石粉，1000rpm搅拌3min，出料，然后与高密度聚乙烯、低密度聚乙烯、乙烯-醋酸乙烯酯共聚物、聚乙烯蜡混匀，投入到双螺杆挤出造粒机挤出造粒，得母料；将母料投到成型机中进行成型、定径、牵引、切割后，即得。
本发明取得的有益效果主要包括但是不限于以下几个方面：
采用金属编织层作为屏蔽层，铜丝编织层柔软性好，使得电缆成品的柔软性提高，并且外绕包铝塑复合膜，使电缆具有良好的抗干扰性，电磁屏蔽性能大大提高；隔热层由合成云母带加工而成，合成云母带除具有膨胀系数小、介电强度大、电阻率高和介电常数均匀的特性，还具有耐热耐火等级高的特性；聚乙烯具有高的拉伸强度、极好的柔韧性、抗化学性及耐辐射性；乙烯-醋酸乙烯酯化学性能稳定，耐辐射，抗老化性能优秀的特点，其和无机物相容性好，共混所得材料性能稳定；聚碳酸酯无色透明，耐热，抗冲击，阻燃BI级，在普通使用温度内都有良好的机械性能；使用四硫化双五亚甲基秋兰姆作为促进剂，配合过氧化物硫化体系使得电缆料的拉伸强度高，压缩永久变形小，综合性能良好，且硫化时间短且充分，制品护套具有良好的耐磨、耐溶剂及耐腐蚀性能；碳化硅强度大，与塑料相容性能好，可作为增强剂来使用。
