1. Insulating and installing the insulators should be handled gently to avoid collision and friction with all kinds of miscellaneous items (wires, wires, tools, etc.) and hard objects.
2. When the composite insulator is lifted, the knot should be hit on the part (fitting). It is strictly prohibited to hit the umbrella skirt or the 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 rattling performance. In order to be cautious, there are still anti-rat measures in the storage yard. If the umbrella skirt is broken or defective, it should be discarded.
