ABSTRACT:
A method and apparatus for isolating electric power lines includes an insulator assembly to which is pivotally connected two line clamps. After the clamps clamp to the wire, the wire is cut so that the insulator isolates the line. In one form the clamping surfaces are curved in the longitudinal direction to make up for the loss of line length due to the elongation of the assembly under line tension. Cut-out assemblies for fuse and disconnect purposes are readily applied to the assembly by a lineman standing on the ground below.
