Claims

[Scope of utility model registration request]

An insulated wire is supported and fixed on the head of the insulator body of a high-voltage pin insulator using a supporting metal such as a band wire or a wrap grip, and the insulator body is attached and fixed to the pin fixed to the same insulator body, and then fixed to the arm on the ground side. In a support device for an insulated wire in a high-voltage distribution line consisting of a current limiting element having voltage non-linearity attached to the insulated wire near the end of the support fitting, and in close contact with one end surface of the element, the insulated wire The non-carrying side electrode provided along the outer periphery of the insulating coating of the element is directly connected to the support metal fitting, or the non-carrying side electrode is placed close to the support metal fitting while maintaining a predetermined insulation distance, and the live side electrode that is in close contact with the other end face of the element is connected to the above-mentioned insulated wire. A disconnection prevention device for an insulated wire, characterized in that it is electrically connected directly to the core wire of the insulated wire.
