The role of connecting fittings in overhead power lines and substations: one is to use connecting fittings to suspend the suspension

insulators on the tower; the other is to use connecting fittings to hang the suspension clamps for straight poles or non-straight poles.

The tension clamp is connected with the insulator string;other connecting fittings such as the cable pole tower and the anchoring of

the pole tower must also be connected with the connecting fittings.

The connection fittings are mainly used for overhead power lines or substations. The conductors or lightning cable strain clamp

insulators are connected through the connection fittings, and the lightning conductor clamps are connected to the tower. According

to different installation conditions, there are two types of special connection fittings and general connection fittings. The special

connection fittings refer to the ball head hanging ring and the bowl head hanging plate connected with the insulator. Universal

connection fittings are suitable for various situations and are classified according to load tonnage. Similar fittings with the same

load are interchangeable, and connection fittings with the same load and different types are interconnected.

The meaning of the letter hanging board number in the product model is:

Q-ball head hanging ring,  P-plane (parallel) contact,   W-bowl head-S-double-UU type, L-link plate,

tie rod, diamond, Z-right angle, Y-extended B-plate T- Adjustment
