Introduction Electrical energy is generated in large thermal and nuclear
power stations .
This network is divided into two parts: Transmission system Distribution system
Support Cross Arm and clamp InsulatorConductorNut & BoltsFuses and Isolating switchesContinuous earth wireVibration damperJumpers
MAIN COMPONENTS
POLES AND TOWERS
A Transmission tower is a structure, usually a steel tower, used to support an overhead power line.
Used high-voltage AC and DC systems,
Height range from 15 to 55 metres
ADVANTAGE & DISADVANTAGE
High cost Tubular poles designed to very difficult Tubular poles may be difficult to climb Wooden pole damage due to fire 20kv above voltage don't use wooden poles
ADVANTAGE
Design flexibility, high strength, light weight, long life, reduced maintenance costs, no damage due to fire
DISADVANTAGE
Reduction in theft of energy
ALL LIFTING TOOLS SHOULD BE LOAD TESTED AS PER STANDARD.
WHILE LOADING AND UNLOADING THE TOWER PARTS, Be CARE FULLY AVOID ALL TOWER ERECTION IN RAINY DAY.
SAFETY
