CABLE SPEARING BASICS

When a shutdown of a cable is required in order for work to be done safely, It is often difficult to determine with absolute certainty that the cable is dead, and therefore safe to be cut. If a worker cuts an energized cable the result may be fatal.

Spearing has become a common Safety practice.

The spearing operation is performed remotely with the operator at a SAFE distance outside the Hazard Zone.

In the event that the cable should be live:

• The spear is designed to short circuit the conductor and cause the breakers to open.
• Blade geometry ensures contact with ALL phases regardless of tool orientation around the cable.
• The spear remains in the cable and will not allow the circuit to reset, reducing the potential for a Live Wire Hazard.

In the event that the cable should be dead:

• Spearing does NOT cut completely through the cable, thus preserving the integrity of the cable and maintaining phase alignment for splicing.

Today, spearing can be used conveniently on cables and joints of a variety of types and sizes. (i.e., Single Conductor, Multi-Conductor, Lead-Sheath or Joint Sleeve) The illustrations in this section demonstrate various head options which make spearing fast and accurate, to ensure worker SAFETY and efficient completion of your next Joint or Splicing task.
