Dhaka Metro Rail Project Overview and Sub-station Installation System

Abstract

I have done Internship under Dhaka Metro Rail Project a Larsen & Toubro (L&T) and Italian Thai Development (ITD) - SINOHYDRO JV Sub-contact of ATS Power Limited. I have set up Dhaka metro rail project a sub-station. I have learned well all the work done in this sub-station. Here are the things I saw and learned, A Sub-station is a part of the Electrical Generation, Transmission and Distribution system. Sub-stations convert voltage from high to low or vice versa or conduct in several other important work. We have bus-bar connections on the primary and secondary side. Each gadget gains freely and processing transformer, circuit related power framework information breakers, disconnection, tap changers, CT & PT, SF6 circuit breakers, isolator, conductor, insulator, lightning arrester, really, and switchgear panels installation, Dry type transformer installation, and Earthing work and Underground cable laying and cable tray more. Dhaka Mass Rapid Transit Development Project MRT LINE -6 has been given to control and manage all the works of Dhaka Metro Rail. Supervising all work and testing everything do this MRT LINE -6.
