The present invention includes a flexible jumper jig which is reconfigurable to replicate the end positions of a flexible jumper as it would be on an installed substation. According to a further preferred embodiment, an exemplary system of the present invention may include a framework forming three orthogonal axes and repositionable tooling mounts for end fittings. According to another aspect of the present invention, an x-axis oriented rail may preferably hold a tooling mount which is configurable to be rotated about its axis to allow for alternate tooling mount orientations. Further, a y-axis oriented rail may be perpendicular to the x-axis rail and may be fixed. Still further, a z-axis oriented rail may be perpendicular to and slide along the y-axis rail. Additionally, a second tooling mount may be attached to the z-axis rail.

Provided is a cross arm with one end connected to a tower body and a free end for connecting a conducting wire. Free end comprises an end connecting piece and an extension piece. Extension piece is fixed with end connecting piece. Extension piece protrudes horizontally from end connecting piece. Conducting wire is connected to extension piece. An angle between extension piece and a cross arm center line is greater than that between conducting wire and cross arm center line. Cross arm free end includes a jumper wire device horizontally arranged on end connecting piece for hitching jumper wire. Extension piece use increases distance between conducting wire and tower body when turning angle condition is met. Gap requirement between conducting wire and tower body is met, and cross arm length increase is eliminated. Horizontally arranging jumper wire device on end connecting piece reduces distance between wire layers and tower body size.

System and method for determining real-time sag and shape information of an electrical power line based on strain distribution along a length of an optical fiber associated with the power line. An embedded fiber coupled to an overhead transmission line measures strain using the backscatter of an optical signal, the optical signal is then interrogated using an interferometer.

A strain release connector for an overhead electrical wire includes a first connector part securable to the overhead electrical wire with a fixed clamping force, and a second connector part cooperable with the first connector part and securable to a service cable with an adjustable clamping force, less than the fixed clamping force. The second connector part has at least one strain adjustment screw for modifying the adjustable clamping force. The adjustable clamping force is set by the at least one strain adjustment screw such that the second connector part is configured to release the service cable upon an application of a predetermined tension force.
