【选型】防护等级高达IP65的多孔穿线板MC 35 FL21，解决配电柜线缆防潮密封问题

时间： 2022-06-19 来源：世强

技术问答

户外使用的高压柜、低压柜、电缆配电柜其防潮密封性极其重要，尤其电缆进线口处容易进入潮气或灰尘，若防潮、防尘不当，易使潮气或灰尘进入配电柜内，影响配电柜的正常使用，降低配电柜的使用寿命。

现有的配电柜进出线密封结构的结构较为简单，多数是通过对电源的外部缠绕胶带安插配电柜的进出线孔进行密封，通过缠绕胶带对配电柜进出的密封性能较差，在进出配电柜时易出现缝隙的情况，降低了密封结构的实用性；同时现有的配电柜进出线密封结构在导线长时间包裹时内部易出现温度过高的情况，从而加速电源线老化的速度，同时易因电源线温度过高出现燃烧短路的情况，降低了密封结构的实用性。

针对上述的问题，特瑞堡有开发出MC 35 FL21系列多孔穿线板，其具有高电缆密度，采用快速简便的组装,产品的材质为热塑性弹性体和玻璃纤维增强塑料，产品的材料使用温度（无应力）宽至-40℃~+100℃，能够在不同环境下可靠工作。可以提供严苛环境下的密封、减振和防护，非常适合给配电柜线缆防潮密封。

MC 35 FL21系列多孔穿线板应用于配电柜具有如下优势：

1、MC 35 FL21系列多孔穿线板的防护等级达到IP65，防护等级高，可以有效防止配电柜外的潮气和灰尘进入配电柜内，保证配电柜的正常运行；

2、安装简单快速，相比于其它密封材料，MC 35 FL21安装只需要将配电柜上开孔，然后螺丝固定，最后剪开穿线板上的孔把线缆穿进去即可；

3、高线缆密度，一块穿线板上可以穿很多条线缆，节约空间，成本和时间；

4、使用温度宽至-40℃~+100℃，能够在不同的环境下可靠工作。
