预制分支电缆的特点 Merits Of Prefabricated Branch Cable
1、 具有优良的供电可靠性
(1) 主干电缆导体无接头、连续性好,减少了故障点。
(2) 预制分支电缆接头采用工厂全程机械化制作,大大降低了人为因素造成质量不稳定现象。
(3) 分支接头结构合理并引进日本先进工艺制作,接触电阻极小,不受热胀冷缩影响。
(4) 短时间完成分支接头成型,避免了接头处铜导体长时间暴露空气中产生氧化而导致接触电阻变化
2、 可明显降低配电成本
(1) 与槽母线比,可降低工程造价,并且技术经济指标高,综合经济效益显著。
3、 品种规格多,选用灵活,任意组合
(1) 主干电缆从10mm2 ~630mm2,,支线电缆6 mm2~400 mm2,任意组合。
(2) 电缆的品种比较多,主要有FZ—VV、FZ—NH—VV、FZ—YJV、FZ—ZR—YJV、FZ—NH—YJV、FZ—WDZ—YJE、FZ—DL—NH—YJV等,可根据需要选用。
(3) 分支接头可根据楼层需要任意设定分支位置。
4、 安装环境要求低,施工方便
(1) 占用建筑面积小,有利于建筑面积的有效使用,对土建的空间尺寸要求低。
(2) 使用环境要求低,安装精度要求低。
(3) 安装简单方便,安装技术要求不高,安装设备仅需一台卷绕机即可,且安装周期短,仅为母线槽安装工时的5%~10%,安装劳动强度低。
(4) 由于电缆的弯曲半径小,大大降低了安装难度,缩小了空间尺寸。
5、 优良的抗震性、气密性、防水性和耐火性
(1) 优良的抗震性,一般机械连接母线槽接头,在墙体受震动后会发生接头松动,而预制分支电缆不会受到影响。特别是在通过建筑沉降缝时不需要任何措施。
(2) 良好的气密防水性,能在潮湿的环境中正常运行,也能在露天及埋地敷设。
(3) 采用“NH”型的预制分支电缆,可在燃烧情况下,保持90min的正常供电运行。
6、 免维护
(1) 预制分支电缆按规定方法安装后,一次性开通率高。
(2) 正常运行的预制分支电缆系统平时不需要做维护保养。
