What is a COD tubeWhat is a COD tube
COD stands for Corrugated Optical Duct (Corrugated OpticDuct). It is a whole composed of multiple internal cable tubes and outer tubes. Shunming COD and traditional general PVC tubes COD pass the manufactured inner tubes (3 to 5) through the reproduction process. ) The method of assembling in the outer tube has created a new era in this field.
Both the inner tube and the outer tube are made of HDPE (High Density Polyethylene) and have a high degree of elasticity. Although most of the inner tubes are provided in the outer tube, they can still be wound around the tube frame. Performance characteristics: Compressive COD products have a special spiral shape, which enhances the compressive capacity of traditional PE straight pipes, and its compressive capacity is several times that of traditional pipes, which improves the effectiveness and elasticity, earthquake, collapse, etc., also Can guarantee safety. Chemical resistance, strong durability, acid resistance, strong alkali ability, better water resistance, laying in seawater and wetland, corrosion resistance, semi-permanent pipeline. Credibility is the ideal cable duct because the material is non-conductive and has high insulation.
In addition, the thermal expansion and contraction of the appearance is quite lower than that of the traditional catheter system, and because of the internal, the appearance of the raw materials is the same, always maintaining the same ratio. Because the COD tube (every 500 meters) is coiled on the tube rack, it can reduce considerable labor costs. The most important thing is that the COD does not need to be inserted into the inner tube, because a variety of inner tubes have been equipped inside the outer tube. Because the lighter gravity COD is quite light, compared with traditional pipes, it is very convenient for construction and transportation. Due to the thread processing, COD can be bent freely, and it can be bent to 90 degrees or even greater angles without any special tools to bend or straighten. It can be bypassed when encountering obstacles at the construction site.
Due to the good single-line design of the inner tube and the very low friction coefficient, there is no connection and no kinking problems. The wire is particularly convenient, and the distance between the holes is also extended. The inner tube is completely air-tight and can resist high internal pressure, and the fiber cable air pulling method can be used. In the case of the same outer diameter, multiple inner tubes can be added to increase the use efficiency. The most important thing is that the COD tube can import up to 75% of the diameter of the inner tube, while the traditional tube can only import 50%. Application range: optical cable, cable protection tube
