Temporary Crossarm Extension

Temporary Crossarm are also known as Extension Arm or Hot Arm. 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.

Temporary Crossarm Attachment – Cat. No. RHHAX72W12

Temporary Crossarms 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.

Crossarm 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.

Temporary Crossarms are designed for brief 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 Crossarms can be used on circuits up to 34.5 kV.
