PURPOSE:To provide a tightening force well maintained even after a processing of drying and insulation treatment, by successively arranging a corrugated insulating board and retainer insulating board, being tightened by an insulating bolt and unt, on outside surfaces of the lead wire supporting pad. CONSTITUTION:On outside surfaces of a lead wire supporting pad 2a of the lead wire supporting pads 2a, 2b, with one end of them fixed to a support post 3 and support bracket, are arranged a corrugated insulating board 6, having an appropriate spring constant, and a retainer insulating board 7 like synthetic resin borad. Those of the above lead wire supporting pads 2a, 2b, corrugated insulating board 6 and retainer insulating board 7 are tightened in one unit by an insulating bolt and nut 4, 5, with a lead wire 1 firmly supported. In this construction, even for the lead wire supporting pad shrinking due to conditions of dryness, the corrugated insulating board 6 will absorb it by its spring action, and a good tightening force can be maitained even after a processing of drying and insulating treatment. |
