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.

Systems and methods for tensioning an electrical cable adapted to be manipulated by one or more remotely operated robotic appendages. Tensioners mounted to a rigid object configured to adjust the tension of a connecting line attached to an electrical cable such that the tension of the connecting line is applied to a length of the electrical cable such that another portion of the electrical cable becomes slack, thereby allowing one or more robotic appendages to remove, replace, repair, or conduct any alteration or modification to said electrical cable or to a rigid object that supports the electrical cable.
