Rainstorms, we often encounter power outages and blackouts, in many cities are very common, in fact, this is mainly rain into the cable duct, soak for a long time, the cable will be aging and thus caused by power failures. This problem can actually be avoided, just for a long time the relevant departments do not pay attention to the municipal construction when the consideration is incomplete, did not seal the cable ducts. Because the underground cable due to management inconvenience, the cable is often soaked in rainwater, or rats bite off, resulting in leakage, power outages, etc., the impact is great, so the use of Cable blockingThe purpose of the device is to eliminate safety hazards and protect the normal use of cables and equipment.

　　at the present time Cable blockingA lot of products, cable pipe blocker belongs to the cost-effective relatively high, which absorbs the domestic advanced level, the use of electric reaming and other advanced technology, with high-quality polyvinyl chloride fibers as the basic material, into the plant fibers, high-strength and high-modulus Vinylon and other raw materials, selected high cement as the main raw material, through the copying of the roll into a new high-tech enhancement of the cable protection tube, the cable protection tube is basically the same process of production, are through the woolen cloth without the top The production process of cable protection tube is basically the same, both are produced through no woolen cloth copying process, the raw materials for the Velcro fiber, high grade cement and other high-strength and high elasticity mold fiber, so the strength is very high, the cable protection tube is thrown through the high-speed polishing machine in the inner wall of the tube to achieve the purpose of reducing frictional resistance of the dense smooth surface, while the cable protection tube is coated with a layer of graphite milk lubricating film on the inner wall of the tube, when the cable passes through the graphite milk lubricating film fracture and produce a slippery surface, the slip surface of these These slip surfaces change the friction between the inner wall of the tube and the cable, thus achieving the purpose of reducing frictional resistance.

　　Cable protection tube in addition to the excellent performance of Velcro fiber cement cable tube also has the following characteristics:

　　1、Cable protection tube has high flow capacity and low thermal resistance coefficient.

　　2, cable protection tube use, and the cable between the friction coefficient is low, the cable through more convenient.

　　3、Cable protection pipe lengthens the distance between wells, reduces the number of work wells, reduces the project cost.
