Three Phase Pad Mounted Transformer Feed Type

Radial feed and loop feed are two common electrical power distribution systems used in transformers. In a radial feed system, power flows from a single source or substation to the loads through a single line or feeder. In contrast, a loop feed system features multiple interconnected sources or substations connected via several lines or feeders.

[Loop Feed]

Form: Input and output power cables form a loop connection at the transformer terminals.

Applicable Scenarios: Typically used for larger-capacity transformers with multiple inputs and outputs.

Advantages: The loop-feed transformer, equipped with six high-voltage bushings, enables a dual power supply configuration. This design enhances the stability of the power system, ensures uninterrupted power supply during faults, and thereby guarantees the reliability of critical applications.

[Radial Feed]

Form: Input and output power cables are directly connected to the transformer terminals without any loop configuration.

Applicable Scenarios: Radial connections are typically used for smaller-capacity transformers with only one input, one feed-through, and one output.

Advantages: This design eliminates the need for additional cables and wiring, ultimately reducing costs, and operates without backup power
