电缆保护管规格型号和电缆保护管材质。
Specification and model of cable protection pipe and material of cable protection pipe.
电缆保护管道系统型号有：PVC-C高压电力管、CFRP碳素螺纹管、HDPE通讯电缆护套管、PVC-U埋地通信电缆管、CPVC高压电力电缆护套管、MPP高压电力电缆护套管)；通讯管道系统HDPE、PVC双壁波纹管、梅花管、三色光缆管、PE过道顶管、硅芯管、PVC方孔格栅管。而每一种型号对应的内外径及厚度长度价格这里就不列出来，详细参数需要厂家提供。
The models of cable protection pipeline system include: PVC-C high voltage power pipe, CFRP carbon thread pipe, HDPE communication cable protective sleeve, PVC-U buried communication cable pipe, CPVC high voltage power cable protective sleeve, MPP high voltage power cable protective sleeve); HDPE, PVC double wall corrugated pipe, quincunx pipe, three-color optical cable pipe, PE aisle top pipe, silicon core pipe, PVC square hole grid pipe. The price of internal and external diameter and thickness length corresponding to each model is not listed here, and the detailed parameters need to be provided by the manufacturer.
电缆保护管材质，一般用电系统用PVC管的比较多；但大平方电缆用钢管比较多。PVC价格低，使用方便，埋地后使用寿命长，不腐蚀。但如果暴露使用，遇火会燃烧，放出有害气体。还有就是水泥管、PVC管（分阻燃和不阻燃）、钢管、玻璃钢管、石棉水泥管、海泡石管、维纶管等，有单根管，也有排管，一般要根据需要选择不同材质的电缆保护管。
For the material of cable protection pipe, PVC pipe is often used in general electric system, but steel pipe is often used in large square cable. PVC has low price, easy to use, long service life and no corrosion. However, if it is exposed for use, it will burn in case of fire and emit harmful gases. There are also cement pipes, PVC pipes (flame-retardant and non flame-retardant), steel pipes, glass steel pipes, asbestos cement pipes, sepiolite pipes, vinylon pipes, etc. there are single pipes, but also row pipes. Generally, cable protection pipes of different materials should be selected according to the needs.
