Power transmission line insulation drainage wire and preparation and installation method thereof

The invention discloses a power transmission line insulation drainage wire and a preparation and installation method, and the method comprises the steps: carrying out the design of the insulation drainage wire for power transmission lines of different voltage grades, selecting a proper conductor, carrying out the integrated insulation transformation of the conductor, coating a semiconductor layer on the surface of the conductor, and uniformly coating a coupling agent on the surface of the preheated semiconductor. And after coating, putting the mixture and silicone rubber into a mold for compression molding, and then putting a semi-finished product subjected to compression molding into a high-temperature box for secondary vulcanization to obtain a finished product. During installation, the suspension clamp is installed at the middle part of the insulated drainage wire, the contact part of the suspension clamp and the wire is made of silicon rubber to avoid abrasion, then the ball head hanging ring is connected
