GENERALINFORMATION&APPLICATIONS

Generally,whenelectricaltransmissionisinterruptedbecauseoneorseveraltransmission towers are damaged, there is a high economical cost for theuClitycompany(i.e.penalCes foreverydayofnon‐transmission).However,therearealsohighpoliCcalandsocialcoststosuchasituaCon.This represents an opportunity for a quick and efficient soluCon totemporarily replacedamaged towers,unCl theuClity companycan removethedamagedtower,buildanewfoundaCon,transportthenewtowertothesite and install it. This process can take as li\le as 1 or 2weeks (tower instock,24hshiVs,efficientteams)oraslongas5or6weeks.By using SBB ERS, the transmission towers can be replaced in just a fewhoursbycreaCngaby‐passandpower transmissioncanbe resumedmuchfasterthanwiththetradiConalmethods.When the new transmission tower is installed, the SBB towers can beremovedasquicklyastheywere installedandputback inacontainerunClthenextuse.Our towers are so versaCle that they can be used for various applicaConssuchas:•  Restoringpowerfollowingadisaster(flood,hurricane,war,etc…)•  ConducCng scheduled maintenance work on exisCng towers without

TOWERCOMPONENTS

FoundaConplate(92kgs;1.2mx1.2m):The foundaCon plate’s role is to support the tower bydistribuCng its weight evenly to the ground. It is placeddirectly on the ground, without the need for a concretefoundaCon.Itcanbeinstalledonaleveledgroundoruptoa 30 degrees angle and can also be complemented by alarger foundaCon plate especially designed for very soVsoilswithminimalbearingcapacity.

SOFTWAREANALYSISPROGRAMPLS‐CADDLITE

This is the main program in which the impact of outsidecondiCons on the tower is analyzed. These condiCons are:weatherandwindloads,thetypeofconductorsandOHGW,thetension on the conductors, the number of conductors perphase, the line angles, the spans, clearance, etc. It is astreamlined version of PLS‐CADD and is very useful to quicklymodelafewspans.PLS‐POLE/LW+MASTThis is amodule to define the capacity of tower components,the number of guy wires, the mechanical capaciCes of theinsulators,thegeometricalcharacterisCcsoftheelements,etc.Bothmodulesarefromtheworld‐renownedPLSsuite,usedbyabout80%ofuClitycompaniesworldwide,andweredevelopedspecificallyforERSuse.
