high quality MV circuit breakers using
Normaclade withdrawable, 12KV, 1600Amp, 25KA
type switchgear, (Manually or Electrically
11KV - 50Hz network, fed from EDL or 11KV
emergency Genset. The power is distributed to 30
satellite substations through three different
medium voltage feeders feed the main 11kV
switchgears in the Utility Plant building, two
feeders from EDL and One from the Main power
plant. The main
11kV switchgears in turn distribute
medium voltage power to different satellite
substations through three busbars.
Cast resin - Dry type transformer 11/0.4KV
250/500/1000KVA 3-Phase, indoor, Mounting and
housing inside cabinet - metal enclosure are
distributed in different substations at
different locations, and transfer the medium
voltage power into low voltage to be used for
The Medium Voltage network is controlled and
monitored through a high technology PLC system.
power management system is designed to manage
the power failure and power restoration, to load
/ unload some satellite substation transformers
according to priority program and the generating
power plant, and to localize earth faults in BIA
main emergency power plant provides a power of
1673 KW through 11KV Genset, 1673 kW of power,
and following 6 cylindrical in-line block engine
A generator panel located in the main 11 kV
switchgear room in C6 building controls this
kind of emergency generators are used at BIA,
these are the low voltage standby generators.
They are designed to insure instant power for
the essential loads during power failures in
different buildings and locations. The following
types are used:
· 910 KVA, 400V , Diesel engine.
· 320 KVA, 400V , Diesel engine.
· 500 KVA, 400V , Diesel engine.
· 1000 KVA, 400V , Diesel engine.
Each of the above Genset has both main and daily
30 type, 22000 lighting units, are located in
the Terminal building, fluorescent, Metal
halide, Halogen and high pressure sodium. Main
distribution boards (MDBs) are fed from the low
voltage side of the step-down transformers,
which in turn feeds, the final branch panels
that supply voltage to different loads.
Various types of lifts with different sizes, in addition to Escalators and Travelators are used to facilitate the passenger's circulation in the airport. They are equipped with many safety devices.
window Cleaning system consists of 3 units one
unit for cleaning the entrance façade windows;
another unit is used for the south façade, and
the third unit for the control tower.
The airfield of Rafik Hariri
international airport is divided into three major runways:
-Runway 03-21 and associated taxiways
-Runway 16-34 and associated taxiways
-Runway 17-35 and associated taxiways
The airfield lighting system for each runway is composed of subsystem that gives the pilot of an operating aircraft visual guidance required by different types of operation depending on the classification of the approach system and the visual range.
