Abstract
A wire cable isolator and an associated energy absorbing restraint is provided for connecting between a device subject to movement due to dynamic loads and possibly thermal deflection, and an adjacent structure, such as a building or a support member. The isolator has predetermined, symmetrical force-deflection properties. The isolator includes first and second pairs of entrapment members, and a wire cable formed in a spiral. The first pair of entrapment members clamp the wire cable spiral at opposite side of the spiral and the second pair of entrapment members clamp the wire cable spiral at opposite sides of the spiral. The first and second pair of entrapment members are disposed at predetermined positions about an exterior periphery of the spiral.
