FAQs
Can PUPI crossarms be field drilled, and where is it OK to drill holes?
Yes, field drilling is acceptable per the PUPI Usage and Installation Guidelines literature. Contact PUPI applications engineers if desired hole locations vary from what is described within the Usage and Installation Guidelines.
Can PUPI crossarms be mounted to flat poles with the standard mount?
Yes, crossarms fitted with standard mounts can be mounted to flat poles with the use of a flat pole adapter bracket. Alternate mounts designs with flat back plates are also available depending on the application.
What is the maximum angle we can turn on a tangent (or deadend) arm?
Maximum conductor angles are entirely application dependent. PUPI has the necessary test data to validate various line designs however, it is highly recommended that end user engineers contact PUPI applications engineers when specifying the appropriate crossarm series for their specific design needs.
What should we look for during routine maintenance and inspection of installed PUPI crossarms?
Routine maintenance procedures for PUPI crossarms are the same for fiberglass as they are for wood. Inspect for damage in high stress locations and around holes if the line has been subjected to an overload type event.
What type of protection do PUPI arms have against UV?
Our thermally bonded SunGUARD® UV coating has shown, in multiple climates, to resist weathering and fiber blooming which ultimately reduces the propensity for arc tracking. This externally applied coating is part of the three-layer UV protection system that gives PUPI crossarms a 60+ year service life.
How much tension can the guy plate on the mount support, and at what angle (single or double attachment)?
30,000 lbs at 30, 45, and 90 degrees.
Are there torque guidelines for installing PUPI crossarms?
Internal TorqueGUARD™ bushings, installed in every factory-drilled hole, prevent crush damage from overtightening. This feature can withstand over 450 ft-lbs of bolt-tightening torque.
What are advantages of the increased basic insulation level (BIL) that fiberglass crossarms provide?
Fiberglass is a non-conductive material and has insulating properties. Other manufactured crossarm materials like steel do are conductive and do not offer this benefit.
What is the service life of the PUPI crossarm assembly?
60 years.
Is there additional lead-time or cost associated with a custom drill pattern for a PUPI arm?
No, custom designs and drill patterns do not add to standard lead-times.
Can a PUPI deadend be mounted where we would be pulling the arm away from the pole?
No, this set up is not recommended because the system strength is then reliant on the fasteners instead of the crossarm and pole.
Does PUPI offer mounts with closed holes instead of open slots (when considering uplift)?
Yes, application specific mounts are available upon request.
PUPI crossarms are available in what colors?
Grey and Brown.
