DESIGN & CONSTRUCTION DETAILS
The pole is constructed by the filament winding process
to achieve optimum results for strength and rigidity.
The filament winding process is continuously applied
with uniform tension onto a rotating mandrel, resulting
in a minimum mass glass to resin ratio of 70:30. The
surface is seamless, smooth and tapered.
The material of the finishing coat is a gel coat that
complies to SANS 1749 and is applied to a uniform
thickness of between 250 and 500 microns, providing a
weatherproof, UV-resistant, flame-resistant and impact-
strong surface in the colour specified.
A standard pole supporting a luminaire with a wind
surface of 0.20m2 may not have a pole top deflection of
more than 5% of its height above ground when subjected
to a basic wind pressure of 500 Pa. A safety factor of 2.5
times the total maximum windload is applicable.
The pole is manufactured in accordance with SANS 1749
under the ISO 9002 quality system.
If an access opening is required, the cut-out is covered
by an access door cover manufactured from glass filled
nylon impregnated in the same colour as that of the
surface coat. It is secured to the pole by two stainless
steel Allen head captive screws into M4 brass inserts
embedded in the pole.
A cable entry with a minimum diameter of 34mm is
provided at a minimum depth of 400mm below the
A hot dipped galvanised glandplate, suitable for gland
no. 0 or 1, complete with terminal block and DIN rail for
a miniature circuitbreaker, is provided and is mounted to
a bolt provided in the access opening.
Poles for direct embedment in the ground can be
provided with a 300x300x1.6mm hot dipped galvanised
base plate complete with 2 x hot dipped galvanised steel
hookbolts and nuts. Base-mounted poles have a hot
dipped galvanised flange plate that can be bolted to a
foundation which is designed to withstand the forces the
pole will experience in service.
