Background technique

At present, in order to protect the urban and rural living and investment environment and reduce the spider web-type overhead power lines in the construction of the State Grid, the power cable transmission lines have been buried from the overhead, and the pipe laying has been widely used in the power industry due to its excellent characteristics. The sheath tube for high-voltage power cable can effectively protect the inner core of the cable. It has been widely used in the transformation of the power grid in the power industry. However, the sheath tube, as a plastic tube, is very sensitive to temperature changes. Concrete and other pipes are very different, and their performance will be significantly reduced under the influence of the environment or external force for a long time, resulting in deformation and damage of the casing, and gradually lose its use function. When the cable core continues to carry current, it will generate high temperature and affect the service life of the casing , In order to slow down the above effects and ensure that the pipeline does not have strength damage during the specified service period, the filling and modification method of the unique particle structure of talc powder is usually used instead of the traditional calcium carbonate as the filler to produce high-voltage power cables. The disadvantage is that the common talcum powder laying device is easy to cause powder blockage due to the characteristics of talc powder being easily raised, which may cause the device to freeze and stop, and the metal components are too hard, which will cause the applied clamping force to be too large and cause the casing to rupture.
