D. The balance point of each pole shall be marked with a permanent mark.
E. Two-piece poles shall have the minimum overlap distance permanently marked on the male
section.
1.4 Fabrication
A. Poles shall be fabricated out of centrifugally cast, ductile iron components. Poles shall be tapered
and shall have a slip fit joint assembly. Poles shall be made with the fewest sections possible to
meet specified pole configuration. Pole sections shall be slip-fitted together with a minimum 30-
ton press to a minimum overlap of 1.5 times the inside diameter of the female section. The air gap
between adjoining sections shall be no more than 1/8” on any side.
B. Field assembly of two-piece poles is standard for poles longer that 70’ poles and available for
shorter poles. Two-piece poles shall have two jacking holes on each piece and holes for a through-
bolt connection installed prior to shipment. After completion of the field slip fit (see technical note
for Field Assembly), a 5/8” Grade A through-bolted shall be installed through the overlapping joint
sections. The field assembly bolt shall be installed in the female section of the two-piece pole prior
to pole shipment.
C. All pole sections will be inspected to ensure minimum thickness by pole class and visually checked
for casting imperfections (See CTQ document for criteria) prior to assembly.
D. Base plates and caps shall be attached to the pole by mechanical (e.g. screwed), fusion (e.g.
welding), friction (e.g. interference fit) or other suitable means. HDPE or TPE caps shall be secured
with a self-tapping screw. Base plate radius must not exceed the pole base radius by more than
1/4” unless otherwise specified.
E. Total length of factory assembled poles shall not deviate by more than +3” or -2” of the specified
length when assembled.
F. The pole sweep (from the butt to the end of the pole) may deviate from being perfectly
straight by 3/8 inches per 10 feet of length. The deviation shall be limited to only one plane in
one direction.
G. Pin joints will be located on the 0° and 180° axes, 6” above the edge of the joint. If the pin joint
conflicts with a customer-specified hole, the pin joint shall be moved to the 45°axis. It is also
allowable that the point join be move 2” towards to tip or the base of the pole if it necessary to
avoid a conflict with another hole.
1.5 Welding
A. No structural welds are required or allowed on ductile iron pole fabrications. Non- structural welds
such as the attachment of base plates and caps are allowed provided that the welding occurs in a
non-loaded area (i.e. below the ground line or above the top most load).
