Capacitor banks help to improve the quality of the electrical power and gives us the more efficient operation of the power system. Capacitor banks are inexpensive if we compare the benefits they deliver to overall power system and can be easily installed anywhere on the network. This specification covers the manufacture, supply, installation, testing and commissioning of 415 Volts, 3 phase, 50 HZ, capacitor banks for power factor improvement in building electrification project.

Most Construction projects requires underground cabling system for its power supply, some times High tension system too. The architects and builders are least bothered about how this cables routed to the premises and equipment. If electrical professionals pointed out the feasibility, the aesthetics of the project would touch to the intended level. Hence, in the planning stage itself the routes and size of the power cable trench to be incorporated in the project design.

Vacuum Interrupter (VI) are vacuum sealed-off devices incorporated in Vacuum Circuit Breakers (VCB) to cause interruption of fault currents in medium voltage electrical distribution systems. The contacts of the VI are pressed against each other under normal circuit conditions. In the event of a fault current, the VCB mechanism effects withdrawal of the movable contact from the fixed contact.

Fire alarm systems have become increasingly sophisticated and functionally more capable and reliable in recent years. They are designed to fulfill two general requirements: protection of property and assets and protection of life. As a result of state and local codes, the life-safety aspect of fire protection has become a major factor in the last two decades.

Fire Alarm System installation work covered by this section of the specifications includes the furnishing of all labor, equipment, materials, and performance of all operations in connection with the whole Fire Alarm System as shown on the drawings and as herein specified. The requirements of the conditions of the Contract, Supplementary Conditions and General Requirements apply to the work specified in this section.
