Abstract
An integral structure integrating an insulator and ground clamps and having an insulation protective cover comprises the insulator. The top of the insulator is connected with one or two ground clamps. The insulation protective cover is arranged on the outer side of a power line fixing clamping plate. The insulator is a wire supporting and fixing member for an electric pole, a transformer and the like. By integrating the insulator and the ground clamps, the integral structure can prevent shakes generated due to the suspension of the ground clamps. During a grounding process, the hooks of grounding rods can be easily hung in the connecting rings of the ground clamps. The operation is very convenient even in a windy condition. The part where the ground clamps and an electric wire are connected is sealed inside the insulation protective cover. The long-time erosion on the connecting part by rain and snow is thus prevented. The enduring safety running of an electric power line is ensured. The electric leakage possibility of an exposed connecting part is effectively eradicated.
