摘要

In many cases insulators are used mounted to utility pole cross-arms. Existing cross-arm materials such as wood, steel and fiber reinforced polymer (FRP) are showing signs of deterioration. In some cases, these other materials can be extremely heavy and difficult to handle or transport into remote access line locations. The Totally Insulated Framing (TIF) System recently developed offers a new cross-arm design that is lightweight, increases cross-arm life and improved safety. The new designs can also offer increased vertical ground clearances, allow use of shorter poles or increased power line operating capacity while also reducing Right-Of-Way (ROW) width requirements. Many utilities involved in extensive transmission line cross-arm replacements find it necessary to conduct this work using live line methods. Line crews are discovering that the equipment available to support the conductors during the change out have mechanical strength and other limitations. The recently developed K-ARM live line tool offers advantages previously unavailable with other such equipment.
