Davit Arms

Superior Electrical Performance – PUPI® fiberglass composite davit arms provide a reliable solution for applications that historically use laminated wood or steel materials. The PUPI davit arm is also a great replacement for the standard steel davit because of the improved BIL & electrical margin offered by a fiberglass product – while also reducing faults from lightning, flashover, and wildlife.

The PUPI standard duty davit arm is an excellent fit for applications requiring medium to heavy conductor loads, or where grid hardening considerations are paramount.

Davit arms are designed for RUS TU-1, TU-1A, and TU-1AA type constructions of 4′ to 9′ lengths. A full range of mount and end-of-arm options are available to support your specific requirements.

Underbuild

Maximize the effectiveness of your lines.

Placing distribution lines on the same pole as transmission voltage circuits help Utilities maximize the efficacy of their poles and line designs. Fiberglass underbuild crossarms provide a reliable and maintenance free solution, which is also lightweight and easy to install.

PUPI® has a wide array of crossarms specifically designed around the requirements of monopole transmission structures, providing line designers the confidence of an engineered product with a 60+ year service life.

Standard RUS constructions including TS-1, TSS-1, and TPS-1 are available; as are a wide offering of custom configurations.

Lattice Tower/Truss.

Lattice Towers, also known as Trusses, have historically been made of steel. PUPI offers fiberglass components to replace steel which creates many benefits for Utilities.

  • Fiberglass is inherently non-conductive – safer for lineman and wildlife.
  • Non-Corrosive qualities of fiberglass maintain the integrity of the structure.
  • Superior B.I.L. helps to withstand surge voltages to protect line equipment in the system.
  • Fiberglass is significantly lighter than steel which makes for easier installation.

Tangent Crossarms

Experience the durability and reliability of PUPI® tangent crossarms.

Pick one up and you’ll see and feel the difference compared to wood or other composite crossarms. PUPI® tangent crossarms weigh significantly less than wood crossarms—with up to six times the strength. A closed-cell polyurethane foam fill provides lightweight, field drillable stability that also prevents moisture and contamination from entering the crossarm. From our industry leading UV protection to our internal bushings, PUPI tangent crossarms are built to last.

This longevity provides a positive total cost of ownership over the life of the crossarm.

Available in centermount, braced, and alley arm applications.

TorqueGUARD™ Bushings

Bushings and Crush Resistance – PUPI® fiberglass crossarms include internal bushings at all factory drilled hole locations. TorqueGUARD™ bushings prevent crush damage from overtightening during hardware installation.

Field Drilling

Agile Installation – PUPI® factory drilled holes are equipped with internal TorqueGUARD™ bushings that prevent the possibility of cracking crossarms by over-torquing hardware, but we understand that sometimes installation conditions necessitate field drilling. PUPI crossarms are filled with a closed-cell foam sealant which permits field drilling to make your installation as agile as you need it to be.Follow these guidelines to ensure consistent performance of your field drilled PUPI crossarms.
