Strongwell’s SE28 fiberglass power transmission
pole has a higher
strength-to-weight ratio than steel, wood or concrete and weighs
substantially less, i.e. approximately 30% the weight of wood, 60%
of steel and 15% or less of concrete.

The SE28 pole is designed using various glass fiber reinforcements
including a multi-directional glass fabric that provides
strength along both the longitudinal and transverse axis.
An internal foam core combines with the high tensile strength
of the composite to give the power poles excellent performance
when subject to vertical and lateral loads. The pole was
developed over a number of years with assistance from electric
power utilities. SE28 poles are tapered and pass the required
ASTM D1036 cantilever strength test.
SE28 power poles are aesthetically pleasing, corrosion resistant
and do not rust or decay. The poles have a smooth exterior
surface and can be supplied in a variety of colors. The poles
are uniformly tapered and multi-sided.

Lightweight and inherently low in conductivity, SE28
power poles are safer than poles made of other materials. Linemen benefit from a lower risk of lifting-related injuries and from the pole's low electrical conductivity property value. Fiberglass power poles can also be more safely erected in the vicinity of energized lines and lifted between conductors on existing structures.
Composite poles are very durable under harsh handling
conditions and can be handled according to the ASCE
guidelines used for steel poles.
Strongwell poles are relatively maintenance free. The poles are resistant to corrosion, acids, water intrusion, fire, temperature changes, microorganisms, insects and birds. Strongwell poles do not, therefore, require the inspection and treatment program that wood poles require.
Fiber reinforced polymer poles have low conductive
properties and have been employed in "live-line" construction.
The SE28 pole is grounded using the same practices as
wood poles.
Depending on the extent of damage, composite poles can be repaired in the field by personnel with the proper training and materials.
