[Abstract]:
In the engineering construction process, often USES the cable protection pipe, but regarding the cable protection pipe concrete function, everybody is clear? The following business treasure for you to introduce the cable protection tube is what and the role of the cable protection tube.
Cable protection pipe also known as cable pipe, power cable pipe, cement cable pipe, power line pipe, power cable protection pipe. Cable protection pipe is mainly installed in the intersection of communication cable and power line, to prevent short circuit accident caused by power line break, causing live communication cable and wire rope, to protect the cable, switch, the core board, so that the whole machine is not burnt out, the interference of the power line magnetic field also plays a certain role in isolation.

电缆保护管的作用有哪些？
电缆保护管是在管子内壁涂复一层石墨乳润滑膜，当电缆穿过时石墨乳润滑膜受力断裂而产生滑移面，这些滑移面改变了管内壁与电缆之间的摩擦方式，从而达到了减少摩擦阻力的目的。
同时使用涂塑电缆保护套管保护电缆可以达到如下优势：
1、良好的耐腐蚀，使用寿命长，可在潮湿盐碱地带使用。
2、电缆保护管载流量高、热阻系数低。
3、阻燃、耐热性好，可在130度高温下长期使用而不变形，遇火不燃烧。
4、电缆保护管使用时，与电缆间的摩擦系数低，电缆穿过时更方便。
5、强度高、刚度高。用在行车道下直埋无需加混凝土保护层，能辊快电缆工程建设进度。
6、电缆保护管加长了井距，减低了工井数量，降低了工程成本 。
7、涂塑电缆保护套管无论是管材还是管件都具有一定柔性，能抵御外界重压和基础沉降所引起的破坏。
8、具有良好的抗外界信号干扰性能。
9、内壁光滑，不刮伤电缆。设计采用承插式的连接方式，方便安装连接。接头处加橡胶密封圈封既适应热胀冷缩，又防止泥砂进入。
