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

Types of Poles & Towers

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

T-pylon design

FUTURE WORK

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.
