HPS has announced the availability of a complete line of low voltage and medium voltage distribution transformers compliant with the new NMX-J-351-1-ANCE-2021 regulation.

The Secretariat of Economy in Mexico, released the new NMX-J-351-1-ANCE-2021 standard on February 11, 2022. This standard establishes higher efficiency levels, general safety requirements, specifications and test methods for LV and MV distribution transformers and replaces NMX-J-351-1-ANCE-2016. The new efficiency levels are expected to reduce energy losses by an average of 18% in low voltage dry-type transformers and 13% for medium voltage dry-type transformers over current efficiency levels. As of August 10, 2022, the country's residential, commercial and industrial applications may comply with these specifications and safety requirements.

HPS low voltage and medium voltage (power) distribution transformer provide a high level of quality and service that has become synonymous with HPS. These transformers are suitable for indoor or outdoor applications including commercial, industrial and renewable energy.
