Abstract
A barrier head bolt for use in power feeder applications including a main bolt portion and an extended torque head portion, the torque head portion designed and constructed to shear off the main body of the bolt at a predetermined torque, and which projects above the main body portion a sufficient distance so as to inhibit or prevent the application of a joint sleeve without first shearing off the extended torque head portion of the bolt, thus ensuring that the joint is properly tightened.
Claims13
A method for connecting a cable to a disconnectable electrical joint wherein the connection is covered by a sleeve, said method comprising:
- positioning a sleeve over a cable;
- providing a barrier head bolt comprising a torque head portion and a main bolt portion, wherein the torque head portion extends from the main bolt portion a sufficient distance such that the sleeve cannot be properly positioned while the torque head portion is attached to the main bolt portion;
- joining the cable to a disconnectable joint via the main bolt portion of the barrier head bolt;
- tightening the torque head portion to a predetermined tightness such that at least a portion of the torque head portion detaches from the barrier head bolt;
- and
- positioning the sleeve over the connection between the cable and the joint.
A barrier head bolt for connecting a cable to a disconnectable joint, and wherein the connection is to be covered by a sleeve, the barrier head bolt comprising:
- a torque head portion and a main bolt portion, wherein the torque head portion comprises an extended head portion and a stem portion and wherein the main bolt portion is designed to connect a cable to a disconnectable joint;
- at least a portion of the torque head portion extending from the main bolt portion a sufficient distance so as to inhibit the placement of a sleeve on the connection between the cable and the disconnectable joint;
- and
- the extended head portion being designed to detach from the main bolt portion at a predetermined torque, such that the sleeve can be properly positioned on the joint.
