Description

MCA型系列电梯随行电缆
技术领域
本发明涉及到电梯随行电缆技术领域，尤其是涉及到一种MCA型系列电梯随行电缆。
背景技术
众所周知，电梯是高层建筑中必不可少的代步设备，要经常的上下运动，为电梯提供工作电源的电缆线也必然地随着其上下运动，而且随着科技的发展和人们工作生活的需要，在电梯内也需要有通讯及监控等一些活动，为此，在电梯旁边还得悬挂相关的信号线，与电梯一起反复的升降，在电梯高速运动中，电缆的风阻大，使电缆频繁受拉，影响使用寿命，而且由于各种线路过于复杂，而且这些线路因其抗拉性能相对较差，在较长期的经常性地升降运动后，有可能出现断裂、损坏，带来断电停驶或其他相关功能中断的后果。
发明内容

在本发明的一个优选实施例中，所述聚乙烯树脂为线性低密度聚乙烯，融指范围0.5～2g/10min，分子量15万到30万。
在本发明的一个优选实施例中，所述相容剂为马来酸酐接枝线性低密度聚乙烯、马来酸酐接枝聚丙烯、马来酸酐接枝高密度聚乙烯中的一种或任意两种以上的混合。
在本发明的一个优选实施例中，所述复配抗氧剂为液体抗氧剂和粉体抗氧剂的混合物，其中所述液体抗氧剂为抗氧剂1135，所述粉体抗氧剂为抗氧剂1010、抗氧剂DLTP、抗氧剂1035中的一种或任意两种以上的混合。
