2. Manufacture process
Round steel Cutting--Heating--Forging--Polishing-Hot dip galvanizing.
Galvanizing: The galvanized hardware fittings have a smooth and uniform thickness of zinc coating without any sharp edges. The fittings are galvanized after subjecting to the processes such as sawing, shearing, drilling, punching, filling, bending and machning.
3. Packing
Ball clevis are packed by plywood case on pallet, which is seaworthy and easy for transportation.
4. Ball clevis application
Link fittings, the ball clevis is fixed on the insulator with cap & pin metal fitting and anchor shackle for overhead lines. The ball clevis is suitable for tension insulator string, suspension insulator string, jumper insulator string, and earthing strings. Arcing horn should be fixed on the ball clevis for high voltage, or requested by client.
