Problems solved by technology
[0002] In many substations, many incoming and outgoing lines use power cables, and they must pass through special cable holes when passing through floors or partition walls. In order to facilitate installation, the diameter of the cable holes is generally larger than that of the power cables. It is required to install a plugging device on the gap between the power cable and the hole, but the existing plugging installation and disassembly are complicated, not resistant to high temperature, and the fire performance is not good, and the gap between the plugging device and the cable hole is too large. Great waterproof performance is not good

The invention provides a cable hole high-temperature-resistant waterproof plugging device. The plugging device is provided with a cable installing hole. Plugging components comprise a front ceramic block, a deformable intermediate sealing gasket, a rear ceramic block and a connection fixing member. The front ceramic block is provided with a front ceramic block installing hole. The intermediate sealing gasket is provided with an intermediate sealing gasket installing hole. The rear ceramic block is provided with a rear ceramic block installing hole. The front ceramic block is provided with a front ceramic block internal fireproof stop and a front ceramic block external fireproof stop. The rear ceramic block is provided with a rear ceramic block internal fireproof stop and a rear ceramic block external fireproof stop so that a front internal fireproof stop ring, a front external fireproof stop ring, a rear internal fireproof stop ring and a rear external fireproof stop ring are formed on the plugging device. A front fireproof groove is arranged between the front internal fireproof stop ring and front external fireproof stop ring. A rear fireproof groove is arranged between the rear internal fireproof stop ring and the rear external fireproof stop ring. The structure of the cable hole high-temperature-resistant waterproof plugging device is great in high temperature resistance and fireproof performance and great in waterproof performance.
Description
technical field [0001] The invention relates to a high temperature resistant waterproof plugging device for cable holes. Background technique [0002] In many substations, many incoming and outgoing lines use power cables, and they must pass through special cable holes when passing through floors or partition walls. In order to facilitate installation, the diameter of the cable holes is generally larger than that of the power cables. It is required to install a plugging device on the gap between the power cable and the hole, but the existing plugging installation and disassembly are complicated, not resistant to high temperature, and the fire performance is not good, and the gap between the plugging device and the cable hole is too large. Large waterproof performance is not good. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to provide a cable hole high temperature resistant and waterproof plugging devic...
