Link fitting are used to link clamps to insulator,or to link insulator and ground wire clamp to tower arms or subjection structure.link fitting have special type and common type in accordance with mounting condition.The special type includes the ball-eye and an socket clevis linking with insulator.The common type is usually pin connected type.They have different grades in according to the load and are exchangeable for the same grade. The meanings of letter &Arabic figures in the catalog are shownas follow.Q-ball eye P-plane parallel W-socket clevis S-double U-Utype L-yoke plate,tension rod thomb 2-900 angle Y-extension B-plate F-square J-strengthen,grading ring T-adjustmentable.Dimerisions of ball and socket for the special type are in accordance with"dimension of balland socket coupling of string insulator unitst-IEC-120 and "Dimension of hanging insulator units forhigh ovltage transminssion line"GB4056-83.
