The development background of column tube occluder

　　 Hangzhou Hengma Power Technology Co., Ltd. is a manufacturer focusing on inflatable cable duct sealing devices, producing column tube occluders, inflatable cable duct sealing devices, tube plugs, lead pipe plugs, inflatable cable duct plugs, cables Ditch plugs, inflatable plugs, pipe plugs, empty pipe plugs, cable pipe sealing devices, polymer moisture-proof plugging agents, meter box plugs, column pipe plugging devices, cable trench waterproof plugging agents, pipeline hidden danger elimination agents, cables Hole plugging manufacturers, etc. This product has filled the gap of soft sealing technology in my country's sealing industry over the past 40 years, and has set a new benchmark for the orderly and sound operation of the electric power communication network. The following describes the development background of the column occluder.

　　 After investigation and research, there are some problems with the market column plugging device. If rainwater enters the pipe, the cable will be soaked in the water for a long time. Although some treatment methods are to drill holes at the bottom of the column tube to achieve the effect of rainwater drainage, but after a long time, small animals or dead leaves and other debris will enter the column tube, block the drainage hole, and cause damage and impact to the cable. What's more serious is that it may cause leakage and large-scale blackouts. Column tube occluder

According to the current market demand, our company has independently developed a simple, convenient and effective column tube occluder product, which solves the problem of column tube cable and reduces the loss of the power supply department. Improved power supply safety efficiency and service level.

　　The material structure of a tube plug

　　The main body of the column tube occluder is composed of reinforced nylon and sealing rubber. Reinforced nylon has excellent wear resistance, heat resistance, aging resistance, high mechanical strength, self-extinguishing and good dimensional stability. Sealing rubber is a high elastic polymer material. Secondly, the tubular plug has good air permeability, resistance to various chemical media and electrical insulation. Given small stresses in different media, the column plugging device will undergo large deformation, thereby providing contact pressure, compensating for the leakage gap, and achieving the purpose of sealing.
