<p><P>PROBLEM TO BE SOLVED: To provide a structure for arrangement of a spacer frame of a boltless cable clamp and a light and inexpensive spacer for transmission cables, which can sharply reduce radio disturbance caused by corona generation to a radio, a television, etc., due to its high potential gradient such as in a UHV transmission line, and corona noise which arises by raindrops, etc. formed around the boltless clamp in rainy weather. <P>SOLUTION: This is a boltless spacer suitable for a UHV transmission cable, which is provided, in opposition at two points of the outside plane of the chamber, with rotation preventing stoppers for keeping the regular setting posture of the boltless cable clamps, when the boltless cable clamps are attached radially, so that gyro motion may be possible, in symmetry about the axis of a frame in the shape of a regular polygon, and the boltless cable clamps are coupled with terminals and are assembled to a chamber, and is constituted so that the clam coupling parts of the boltless cable clamps may be positioned, being displaced right and left by±θ°from on the axes of symmetry of a polygonal conductor which becomes the largest potential gradient. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
