Description

一种低烟低卤抗紫外线防虫防蚁的电缆料
技术领域
本发明属于电料料领域，更具体的说涉及一种低烟低卤抗紫外线防虫防蚁的电缆料。
背景技术
随着科技的发展，电力系统更多的被应用。其中电缆作为电力系统传输电能的必要设备被广泛应用。随着电力系统的越来越晚上，电力系统给应用的位置和场合也越来越多。在地下工程和户外郊区电力系统中，电力电缆的使用更多，且工作环境更加恶劣。由于地下的特殊环境，放置在地下的电力电力常常会被虫蚁或老鼠叮咬，导致损坏破碎，使得电力系统不能正常工作。
据不完全统计，一只老鼠每星期要啃咬18000～90000次以上，并且其牙齿硬度比铜大，只有硬度超过合金钢的物质才可以保证不被鼠类咬坏。如2010年12月8日下午，一只20多厘米长的老鼠咬破一根185平方毫米电缆，导致华能长春热电厂(长春热电四厂)2号机组故障停机，长春市城区600余万平方米供热面积受到影响。经过一天一夜时间抢修才恢复供热。在已运行的光缆线路上，多厂家的多种结构光缆都都出于鼠咬而造成不同程度上的线路故障。以浙江移动通信有限公司所属线路为例，从1997年到2015年由于鼠咬发生的通信故障数十起甚至更多，严重超过了电信线路的故障率要求。虫蚁和老鼠的危害之大，由此可见。据不完全统计，每年由虫蚁和老鼠直接造成的经济损失约200亿美元，如果把老鼠造成的各种损失加起来，可达上千亿美元。而随着工业自动化程度提高，老鼠造成的损失也更加严重。
其它虫类对电缆、光缆的危害也极其严重，如果防虫防治工作没有做好，可能造成大面积的停网、停电现象。尤其是蚁患，因蚁患造成通讯故障占60％，广东最高占80％，而湖北则占到了56％。通讯电缆因蚁害发生故障，轻者降低通讯质量，重者可导致通讯中断。电力电缆遭虫类咬穿护层后，可能引起短路事故使电力输送中断，甚至酿成火灾。铁路讯号电缆因虫蛀失灵后，使运输安全受到严重威胁。
