The design of OHTL tubular steel poles for 11 KV transmission lines should adhere to AISC standards, with companies like TAPP offering poles up to 110 feet. However, the specific height and design can vary based on local conditions such as voltage level, wind velocity, and temperature. There is no one-size-fits-all standard for these poles, making it essential to consider various factors for each location. Relevant standards to consult include ASCE’s Design of Steel Transmission Pole Structures and ANSI/NEMA standard No. TT1. Understanding these guidelines is crucial for effective pole design.

Does anybody knows a standard way of determining the hight of 11 KV transmission line galvanised steel poles ?

Welcome to Physics Forums Magwa.

Steel poles for transmission lines are designed to AISC (American Institute of Steel Construction) standards. Looks like this company makes them up to heights of 110 feet.

Thank u so much dlgoff , but i am looking for the standard that TAPP and its similar companies are using to design the OHTL tubular steel poles bec. as far as i can understand that every location is going to have its own structure according some variables like voltage level of the line , wind velocity , temp. , etc. and there is no particular standard poles to be used. So i hopefully am trying to find these standards (ASCE’s Design of Steel Transmission Pole
Structures, and ANSI/NEMA standard No. TT1 latest edition,) in order to design my case.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
