CANTILEVER FOR SUPPORTING LIVE CABLES OF RAILWAY, TROLLEY AND SUBWAY LINES

摘要

A cross arm for supporting liverail-way, trolley and subway lines comprising across--member (8) fitted with means of connection to anassociable support structure (16), at least a firstelectric insulator (20) joined to the cross-member(8) and able to support a first live electric cable,electrically insulating it from said cross-member(8). Advantageously, the cross-member (8)com-prises a body (24) having a mainly longitudinal(X--X) extension and at least a first attachment portion(28) fitted with a 'U' shaped profile able to form ashaped coupling with said first electric insulator(20). The first attachment portion (28) defines afirst seat (32) for the continuous adjustment of thelongitudinal position of the electric insulator (20)along the cross- member itself.
