Distribution Sector Duties:

Power is Transmitted and Distributed by many ways:

1. Stable and mobile distribution power stations 33/11 kV by different capacities
2. High voltage power transmission lines 33kv.
3. High voltage power transmission lines 11kv.
4. Distribution transformers by different capacities 4.0kv.
 

Power Distribution System Elements

1. Power Transmission Lines 33kv:
   Iron poles in different lengths are constructed, some can bear one circle the other two. Round (chain) or pin insulators 33kv can be used, and multi- size conductors, some cables are used like (3×150 squ.mm / 1×400 squ.mm) 33kv.
2. Transforming Stations 33/11kv with different capacities:
   start from (2× 5 MVA) to (2×5,31MVA), complete and equipped with circuit barkers and protection devices and sources of continuous current D.C.
    
3. Midd-Power Transfer Lines 11 kV:
   some are executed by the use of overhead cable lines 11kv, from the stations to the consumers.
4. Distribution Transformers 11/0.4:
   some are hanging with overhead cable lines, others are installed inside huts.
5. Low Voltage Networks:
   they are executed either by overhead cable lines or (hang twisted cable).
6. Lighting Networks:
   it is executed by using a different size poles (start at 10m to15m) with lights (125w to 400w) by different kinds, some are called Sodium, and some are mercury.
