HT lines are used to transmit electrical power over long distances from power stations to substations
Typically from 11 kV to 765 kV.
Made of aluminum or steel-reinforced aluminum.
Prevent electrical contact with supports.
Support the conductors; towers are used for higher voltages.
Clear the path and set up access routes.
Install foundations for poles or towers.
Erect and secure them.
String and tension the conductors.
Fit insulators and secure conductors.
Regular inspections and preventive maintenance to ensure safety and functionality.
LT lines distribute power from substations to end-users like homes and businesses.
Typically from 230 V to 440 V.
Often aluminum or copper, insulated.
Keep conductors from touching the poles..
Usually wood, concrete, or steel.
Plan the route and pole locations.
Set and secure poles.
String conductors between poles.
Ensure proper insulation.
Connect to transformers and distribution boards.
Regular inspections and preventive maintenance to ensure safety and functionality.
