The transportation and installation of the insulator shall be taken good care without any throwing or collision ,fiction with various sundries(wires,iron plates and tools etc.)and solid material.
When suspending the composite insulator,the knot shall be made on the attachment at the end.Knots on shed or sheath are strictly prohibted.When the rope has to be contacted with the shed or sheath,
the contacting area shall be pached with soft cloths.
Never apply the composite insulator as the assistant tool for the wire distribution and collection and collection in case that the insulator can be damages by impact or bending moment.
Do not step on the insulator shed with foot.
When installing the grading ring,attention shall be attached on the adjustments to make sure that the ring is vertical with the axial of the insulator.
And for opening grading ring,the opening directions at both ends shall be consistent to facilitate the discharging and protect the shed.
