Cable seal is a pipe sealing technology. The main function is to prevent sewage and rainwater from flowing into the pipeline, causing cables to run at risk by immersing in water for a long time, preventing sewage and rainwater from seeping through the pipeline, and endangering the operation safety of adjacent maintenance wells or substations/opening and closing stations; Cable seal can prevent sewage from being Sediment and garbage are brought in to block the cable pipes and affect the later line inspection and maintenance; prevent small animals from entering the cable pipes, gnawing and destroying the cables, and multiplying and running in the pipes.

The history of Cable seal. With the rapid development of my country's economy and the gradual improvement of various urban infrastructures, higher standards and requirements have also been put forward for the construction grade and maintenance efficiency of underground pipelines. In the past, the underground communication and power protection pipes were mostly made of plastic, glass fiber reinforced plastic, cement, and other materials, and were pre-buried in the underground trenches dug in advance, and artificial wells were set at standard distances for wiring, inspection, emergency repair, Maintenance, and other construction work points.
The main body of the artificial well is made of bricks and cement, and each artificial well is connected by pre-buried pipes. If the waterproof sealing of the cable seal is not handled properly, over time, there will be water seepage, water accumulation, sediment, and mouse breeding in the pipeline, which will affect the safety of the cable itself and the maintenance and construction, and even cause serious damage. Accidents such as power outages or signal interruptions.
At the same time, because the pipelines are connected, the accumulated water in the pipelines flows along the terrain. It takes a lot of time to pump water before maintenance, which greatly hinders the speed of emergency repairs. If the water pumping can be achieved in sections, it will undoubtedly greatly improve the speed of emergency repairs. Therefore, it is necessary to adopt relatively advanced technologies and products to solve the problems of safety prevention and later construction and maintenance of underground cable seals.
