Abstract: What is disclosed is an insulator for providing insulation between a stringing block for an electrical conductor and a pole or cross arm on which the stringing block is mounted. The insulator is made of a non-conductive material such as plastic. The insulator has an upper opening in the body that is configured for receiving a flange of a stringing roller. The insulator can be configured to be mounted directly to a pole or cross arm, such as by using a ratcheting strap. Alternatively the insulator can be configured to be positioned between the roller and a base, such as those known in the prior art.

Abstract: A portable cross arm support device for temporarily supporting electrical conductors of a power transmission or distribution system. The portable cross arm support is configured for vertical lifting of the conductors. The portable cross arm is configured to fold for facilitating transportation. The portable cross arm has a main support pole mounted in a lifting bracket. Embodiments of the portable cross arm utilize a worm gear lifting system for vertical lifting of the conductors. The cross arm has two opposing horizontal line arms configured to support the electrical conductors. The opposing horizontal line arms extend from a T-connector. The T connector allows the horizontal line arms to pivot to a vertical orientation to provide for folding of the portable cross arm.

Abstract: A grounding attachment for use with a CRS Roller. The grounding attachment has a body having two arms. Each arm is pivotally attached to the body. The arms are configured to be biased downward onto a conductor positioned on the CRS Roller. Preferably a torsion spring biases the arms downward such that a roller attached to each arm rests on a conductor positioned within the radius block. Energy is conducted from the conductor, through the roller and arm to a grounding lug that is configured for a lineworker to attach a ground to the grounding device to allow the energy to reach the earth.

Abstract: A nonconductive line holder for repositioning a conductor for a line worker to safely work. The line holder has a head, a shaft, and a base. The head is configured to receive and secure a conductor. The shaft can be adjustable or nonadjustable. The base is configured to attach to a base. The line holder attaches to the base and allows a line worker to adjust the positioning of a conductor within the head.

Abstract: An aggregation roller for extending a conductor over a span for electrical distribution. The aggregation roller is useful providing safety for linemen, adaptability to new technologies for conductors, low friction to easily pull the conductors and durability. The aggregation roller is useful in reducing the chances of electrocution of the lineman when the aggregation roller is near energized conductors. Further, the aggregation roller replaces multiple rollers as is used today.
