Product Description Product description▲Corrugated optical cable protection tube (corrugated optic duct), referred to as COD for short, also known as six-hole integrated sleeve type high-density polyethylene communication tube. It is a whole composed of multiple internal cable pipes and outer pipes. COD is a six-hole integrated tube formed at one time through high-tech technology. Both the inner and outer tubes are made of HDPE (high density polyethylene), which has a high degree of elasticity, and although most of the inner tubes are inside the outer tube, it can still be wound around the tube frame well. Because the material does not conduct electricity and has high insulation properties, it is an ideal cable pipe. In addition, the thermal expansion and contraction of the appearance is much lower than that of traditional conduit systems, and since the raw materials of the inner and outer pipes are the same, always maintain a uniform ratio, COD can be bent freely, and can be bent by force up to 90 degrees or more, and no special tools are required to bend or straighten it. Obstacles can be bypassed at the construction site. Most importantly, COD can import optical cables with a diameter of up to 75% of the inner tube diameter, compared to 50% of the traditional tube. Product Features Product Characteristics▲COD products have a special spiral shape, which enhances the compressive capacity of traditional PE straight wall pipes, which is 8-10 times that of traditional pipes, and improves the effectiveness and elasticity, and can play a good safety guarantee especially in the event of earthquake, collapse, etc. ▲Chemical resistance, strong acid resistance, strong alkali resistance, excellent water resistance. It can be laid in seawater and wetlands, and is corrosion resistant, and is a semi-permanent pipe. Product applications are optical cables, cable protection tubes
