Power Transmission Tower  A  transmission tower  or  power tower  (alternatively  electricity pylon  or variations) is a tall  structure , usually, a steel  lattice tower  used to support an  overhead power line . Power transmission tower consists of the following parts:- 1) The peak of the transmission tower  2) Cross arm of transmission tower  3) The boom of transmission tower  4) Cage of transmission tower  5) Transmission Tower Body  6) Leg of transmission tower  7) Stub/Anchor Bolt and Baseplate assembly of a transmission tower.  The main parts of these are shown in the pictures. The peak of Transmission Tower The portion above the top cross arm is called the peak of the transmission tower. Generally, earth shield wire connected to the tip of this peak. Cross Arm of Transmission Tower Cross arms of transmission tower hold the transmission conductor. The di...

Sub-Station It is a conversion point between transmission-level voltages (such as 138 kV) and distribution level voltages (such as 11 kV). A substation has one or more step down transformers and serves a regional area such as part of a city or neighborhood. They are connected to each other by a transmission ring circuit. Equipment and its function 1). Lightening Arrestor This is the first component in an electrical substation, and the principle capacity of these segments is to shield the segments of the substation from passing high voltage just as stops  the amplitude and duration of the flow of current . The light arrestor segments are associated among the earth just as a line which mean parallel to the parts under resistance at the electrical substation.    Bushings and Lightning Arrestor These parts divert the flow of current to the ground and hence secure the framework's conductor just as protection from damage. Th Lightning Arrestor does no...
