The PT adjustment plate belongs to the connection fittings in the power fittings, and is an adjustable parallel hanging plate. Parallel boards are use to connect single boards to single boards and single boards to double boards. Only the assembly length can be change, and the connection direction cannot be change. The parallel hanging plates are mostly make of medium and thick steel plates by stamping and cutting processes.
PT hanging board double corner insulator string and tensile insulator string are use. In use, the distance between the two suspension points of the fixed insulator string is calculated according to the number of rotation angles of the corner tower, and an adjustable length should be added to one of the strings to adjust the length.
