Technical measurement standard of ball and socket connection fittings:

  Ball and socket connection fittings are special connection fittings, including ball head hanging rings (Q-type, QP type, QC type and QH type) and bowl head hanging plates (W-type and WS type); Parallel hanging plates and right angle hanging rings are mainly used to connect slot insulators Ball and socket connection fittings are used together with ball and socket suspension insulators; The connection size shall be compatible with the ball and socket connection size of insulator string elements in the national standard
Therefore, the ball and socket connection fittings shall be installed in coordination with the ball head and ball and socket technology of insulator connection, and shall comply with the provisions on the connection structure and size of suspension insulator of high voltage line The locking pin matched with the ball and socket connection hardware, and the R-type push-pull pin adopts the locking pin of 210 kn and above; W-type push-pull pin adopts 160 kn and below locking pin of XP series insulator; The utility model is characterized in that during insulator loading and unloading, the pin only needs to be pulled out from the pin hole without taking out (still hanging in the cap socket) and can be re driven, so as to facilitate the loading and unloading of the locking pin and avoid the loss of the pin Power fittings http://www
