<p>PROBLEM TO BE SOLVED: To arrange a cable head unit at the farthest end portion in a unit paralleling direction, when installing lightening arresters equipped with simplified disconnectors and instrument transformer units, together with cable head units. SOLUTION: A transformer element E13 for line and a lightning arrester element E11 arranged vertically are connected with a simplified disconnector element E12 , thereby forming a lightning arrester-instrument transformer unit U1 . A cable head unit U2 is arranged at the farthest end portion of unit paralleling direction, and the lightning arrester-instrument transformer unit U1 are arranged between the cable head unit U2 and other unit U3 . Operating shafts 75, 97 which operate a simplified disconnector ds are led out perpendicular to the parallel direction of the unit, and in this way, the simplified disconnector ds can be operated without being disturbed by the cable head unit U2 .</p> |
