C (392 deg. F).

Emergency Power Diesel Generating Set In Electrical Construction

This article covers the manufacture, supply, installation, testing and commissioning of 415 volts, 3 ph, 4 wire, Diesel Alternator Set (Diesel Genset). The set shall be mounted on common base frame and complete in all respects including the auxiliary equipment such as battery auxiliary, lube oil pumps, filters, oil storage tank, centrifuge, etc. including piping required for interconnection between the set and the auxiliaries which are mounted separately.

Engineering and Technology

Engineering and Technologies are, in the first instance, simply extensions of the human body, allowing us to overcome the physical limitations with which we are born, and to adapt the natural environment to our own needs. Technologies are inventions of humans that have allowed us to survive, and have enabled our cultures to advance. They are for the most part material objects: tools, for example, are simply detachable additions to the body, the manufacture of which generally distinguishes humans from animals.

Installation of Audio Intercom System For Building Project

Audio Intercom System being used in high-rise buildings or commercial complexes, provide two way communication from entrances, gates, go-downs, industrial plant rooms and normal doors, to an internal audio handset. It can be used to screen authorized visitors from outside entrance and useful to communicate internally between persons from one room to another room or office spaces. It can also be used to function as effective public announcement system.

Medium Voltage Cables (MV Cables) In Electrical Construction

The contractor shall supply, install, test and commission the 13.8 KV cable network as shown and indicated on the contract documents. Conductor sizes shall be metric as shown, conductor sizes with cross sectional areas smaller than specified will not be accepted. The cable installation shall include all trench work, sleeves, ducts, and all necessary fixings and cable terminations at both ends of the cable. The contractor shall supply and install cable marker posts to indicate the route of all underground cables. Markers shall be provided at every bend along the route and at sites of crossing roads or pipe lines.
