A low-profile catenary hanger, catenary wire system, and a method for supporting an electrical contact wire in relation to a messenger wire wherein a wire clamping assembly clamps about the contact wire, and a wire corral assembly is fixed to the clamping assembly. The corral assembly defines an adjustable reception corral through which the messenger wire is received without fastening so that the contact wire can rise without a consequent lifting of the messenger wire. The clamping assembly has a first clamping member with a keystone-shaped projection and a second clamping member with a keystone-shaped slot that can slidably receive the keystone-shaped projection to fix the clamping members together by operation of a setscrew. The clamping members together define a wire reception volume, and each clamping member has an engaging tooth whereby a contact wire with opposed longitudinal grooves can be clamped and retained by the clamping assembly.

A cantilever assembly includes a cantilever arm having longitudinal fastening channels and slots in communication with the fastening channels. The assembly also includes an attachment bracket featuring a first leg portion and a second leg portion defining a seat there between with the leg portions featuring apertures. Bolts having threaded shafts are positioned through the apertures of the attachment bracket and engage the threaded bores of nut plates positioned in the fastening channels of the cantilever arm. As a result, when the bolts are turned, the nut plates engage side walls of the fastening channels and the distal ends of the bolts engage a central pipe portion of the cantilever arm.

A clamp for a wire of an overhead line comprising a main body has a groove for hosting the wire, a first and a second tapered region located in respective ends of the groove, and a first and a second spring placed in respective holes on opposite sides of the groove. The first and second springs are located in a central portion of the groove and are arranged for pushing respective wedges into the tapered regions in opposite directions. The wedges are arranged for tightening the wire by blocking between the wire itself and a wall of the respective first and second tapered region.
