    any designer wants to optimize his design for industrial buildings by completely satisfying the users’ individual needs for these buildings which are: 

    1- Workshop and office flexibility.

    2-Production facility availability, continuity of service.

    3- Time, investment and operating cost control.

    these needs must be satisfied in the following three levels of electrical design for power distribution architecture which are:

    1- General distribution.

    2- Sub-distribution.

    3- Final distribution.

    Actually, Each industrial site has its own particular needs and requires a specific type of power distribution architecture based on the following principles: 

    1- Cost optimization, which is closely, linked to the location of the MV/LV substations, 

    2- Availability, which is primarily governed by the higher levels of the architecture, 

    3- Flexibility, which is based mainly on the sub-distribution and final distribution design.

    These principles can be applied in different types of power distribution architecture, especially in the common three types which are: 

    1- “Radial branched” power distribution architecture,

    2- “Dual-transformer shared” power supply distribution architecture,

    3- “Multiple-transformer shared” power distribution architecture.

    the first type of power distribution architecture; “Radial branched” was explained before in a previous topic and today I will continue explaining the other two types as follows: 

    “Dual-transformer shared” power supply distribution architecture.

    This power supply distribution architecture meets the needs for increased flexibility and availability for all industrial buildings.

    The electrical design levels in this power distribution architecture will be as follows:
