A distribution gap core (DG core) for a pad-mount transformer is typically a wrapped core design made of grain-oriented silicon steel that is widely used for its cost-effectiveness and efficiency in power distribution. This design uses a simple clamping method, resulting in faster manufacturing times and lower costs, and is engineered for applications like residential power distribution. It is known for having a high efficiency and a reliable service life.

distribution gap core Key features and benefits

 

Design:

The core is often a simple, wrapped design, sometimes referred to as a "distributed gap core". It is commonly a rectangular, five-leg core with a wrapped (toroidal) design.

 

Material:

It is constructed from grain-oriented silicon steel, which has excellent magnetic properties for reducing core losses and increasing efficiency.

 

Manufacturing:

The design facilitates faster assembly times and lower manufacturing costs compared to other core designs due to its simple clamp design.

 

Performance:

The design is known for high efficiency, with the grain-oriented steel minimizing hysteresis and eddy current losses.

 

Cost:

It is considered the most cost-effective choice for pad-mount transformers in distribution applications.

 

Application:

It is the standard choice for single-phase and three-phase distribution transformers that are part of a utility network connecting to end-users via underground lines.
