<p>PROBLEM TO BE SOLVED: To prevent overheating in a connection metal fixture and an anchor metal fixture or in a connection point of these fixture, by interposing an insulating material between the anchor metal fixture and a power transmission line. SOLUTION: In a support object 10, an insulating arm 20 is mounted into quadrangular pyramid shape, to a tip end part thereof, an anchor metal fixture 30 is connected through a connection metal fixture 40 and an anchor clamp 50, a power transmission line 50 is anchored, and a jumper wire 80 is connected to a jumper socket 70. Between the anchor metal fixture 30 and the power transmission line 60, an insulating material 100 is interposed. In this way, another separated electric circuit flowing from the power transmission line 60 into the one side through the anchor clamp 50, connection metal fixture 40 and the anchor metal fixture 30 to the power transmission line 60 into the other side can be disconnected. Consequently, overheating in the connection metal fixture 40 and the anchor metal fixture 30 or in a connection point of these fixtures is prevented.</p> |
