BOX SECTIONS
Box sections are made from structural aluminum and are used for mounting horizontal post insulators. Box sections weigh 265 pounds and are installed between column sections and have pre-drilled holes on two sides to allow mounting of any line post insulator. In addition to structures using horizontal Vee insulation, box sections are used on tension towers for mounting the jumper insulation.
A box section and two 7157 guy plates are assembled between column sections in this horizontal Vee structure.
INSULATORS AND HARDWARE
In addition to structure components, the Lindsey Emergency Restoration System includes insulators and conductor hardware. Lindsey highly recommends the use of polymeric suspension and post insulators, due to their high strength, lightweight and durable construction. Hardware components are selected to provide the greatest number of assemblies with the least number of components.
The
advantages of polymer insulators are demonstrated above. The linesman is easily
carrying a 40,000 lbs. suspension insulator suitable for use at 500 kV.
Providing a complete system assures the proper fit of all insulator and hardware assemblies.
ANCHORING SYSTEMS
Anchoring
is a critical element of the guyed Lindsey Emergency Restoration
Structure. Depending on the prevailing soil conditions, a number of
different anchoring arrangements can be provided. Cross plate anchors are
the most common and universal anchoring method, requiring minimal installation
equipment. Screw anchors, rock anchors and dead weight anchoring systems
can also be supplied to meet specific requirements.
In most cases, cross plate or screw anchors are the quickest and easiest type of anchoring.
Designs
for a dead weight anchoring system, consisting of nested concrete blocks, are
available for situation where other anchoring systems will not work.
