Hot Arm are also known as Extension Arm or Temporary Crossarm. These devices are typically used for temporarily holding conductors while utility lineworkers change damaged insulators or crossarms on pole structures. Hot Arms are also used for moving conductors away from a work area such as a road widening.
Hot Arm for Crossarm Attachment – Cat. No. RHHAX72W12
Hot Arms are part of Rauckman Utility Hotline Tools products. These round arms are 2.5″ in diameter and constructed of foam-filled fiberglass. When new and clean these arms meet the requirements of ASTM F 711. In order to sustain the electrical insulating and mechanical characteristics the fiberglass poles should be maintained and tested per ASTM F3121.
Hot Arm for Pole Attachment with 36″ Chain – Cat. No. RHHAP34CB1
Wireholders have a generous 1” opening to accept conductors up to 795 ACSR. Each wireholder has a one-way captive latch that must be released before the conductor can be removed.
Hot Arms are designed for temporary application on 15 kV circuits. In inclement weather or if the arms are left out overnight the addition of insulators on the wireholders is recommended. If insulators are installed these Hot Arms can be used on circuits up to 34.5 kV.
