ologies during hands-on lab exercises. The communication mediums were twisted pair, optical fiber, infrared, and generally wireless radio.
Objective of the project:-
The main consideration in the present field technologies are Automation, Power consumption and cost effectiveness. Automation is intended to reduce man power with the help of intelligent systems. Power saving is the main consideration forever as the source of the power(Thermal, Hydro etc.,)are getting diminished due to various reasons.
The main aim of the project is Automatic street power saving system ..................[:=> Show Contents <=:]

BRIEF DESCRIPTION:
Vacuum brazing furnace is meant for brazing similar or dissimilar metals in clean conditions. As a result oxidation is avoided and good braze strength along with fine surface is obtained. Hence further surface cleaning is not required. The furnace is designed to achieve a maximum temperature of 1350deg C and vacuum level of 5*10power -6 in cold condition. The furnace chamber size is 1.2mts and length of 1.5mts; working area is 800sqmts.the dish of furnace can be moved down for loading jo..................[:=> Show Contents <=:]
