1. The insulator should be handled gently during transportation and installation to avoid collision and friction with all kinds of miscellaneous pieces (wires, wires, tools, etc.) and hard objects.

     2. When the composite insulator is lifted, the knot should be hit on the component (gold fitting). It is strictly prohibited to hit the umbrella skirt or sheath. When the rope must touch the umbrella skirt and the sheath part, it should be wrapped with a soft cloth at the contact part.

     3. The formula of the insulator skirt material considers the repeller performance. In order to be cautious, there are still anti-rat measures in the storage yard. If the shed is broken or defective, it should be discarded.
