GNEE Steel unit substation transformers
A unit substation transformer steps down utility distribution voltages to ideal in-plant distribution voltages that match operating conditions. They can be applied inside or outdoors and consist of a close-coupled assembly made up of three main parts: Primary electrical distribution equipment,A three-phase power transformer ,Secondary electrical distribution equipment.

Advantages of unit substations transformer
Unit substations transformer provide many advantages compared to traditional approaches of stepping down utility distribution voltages. For example, the close-coupled design allows the transformer and electrical equipment to be located in close proximity to the load concentration, which minimizes the lengths of cabling and buses to reduce power losses and exposure to faults. This close-coupled design can also improve voltage regulation and service continuity.

Compact Substation Transformer Feature
1 - Made up of HV switch compartment, LV switch compartment, relay protection compartment and transformer compartment. Enclosed of HV, LV compartment and relay protection compartment can be made of aluminum alloy plate, steel plate of composite plate.
Aluminum alloy plate is an anodic oxidation treated to strengthen its corrosions stability. Steel plate and steel structured parts are all phosphating treated and the composite plate is featured with vivid appearance, heat insulation and fire retardation.
The transformer compartment is arranged with safe guard protecting net but no enclosure, which not only guarantees better thermal diffusivity but also is able to insure person and equipment against accident.
2 - HV switch compartment: The HV switch compartment can be mounted with 35KV switchgear or load switch Aerial cable type available for mounting 35KV inlet wire.
3 - LV switch compartment: When LV side is 10KV, LV switch compartment can be mounted with 10KV and 12KV switchgear ,10KV RMU
4 - Power off protection compartment: The power off protection compartment is mounted with AC panel, DC panel, signal panel, protection panel, motion control panel (RTU), carrier wave machine panel or optical fiber termination set.
