Certified Engineering You Can Trust.
At Delta Electric, every transformer is built under ISO 9001–certified processes and in full compliance with NMX, ANSI, IEEE, and NEMA standards. Our commitment to reliability is demonstrated through rigorous testing, technical transparency, and traceable manufacturing in every stage of production. These certifications are more than requirements they are the foundation that ensures continuity, safety, and long-term performance for the industries that depend on our engineering.
ISO 9001:2015
Certifies that our manufacturing operates through controlled, repeatable, and auditable processes. This ensures consistent quality in engineering, materials, testing, and operations, giving clients confidence in every transformer we deliver.
UL (Underwriters Laboratories)
UL compliance allows our transformers and electrical assemblies to be installed in the U.S. without restrictions. It ensures safety, reliability, and adherence to OSHA, NFPA, and local authority requirements—reducing project risk and increasing acceptance for industrial and custom applications.
IEEE / ANSI
NEMA standards ensure that our enclosures and components meet U.S. requirements for durability, protection levels, and environmental resistance. This improves acceptance in EPC and OEM projects and positions Delta as a trusted supplier of compliant equipment.
NEMA
(National Electrical Manufacturers Association)
NEMA standards ensure that our enclosures and components meet U.S. requirements for durability, protection levels, and environmental resistance. This improves acceptance in EPC and OEM projects and positions Delta as a trusted supplier of compliant equipment.
NMX-J-116
NMX-J-116 validates the technical performance of our distribution transformers in Mexico, ensuring compliance with national requirements for losses, impedance, and mechanical behavior. It strengthens our competitive advantage and supports reliable, efficient operation in local industries.
NOM / ANCE
NOM/ANCE certification confirms that our transformers meet Mexico’s mandatory electrical safety standards. It enables unrestricted market participation and ensures that each unit complies with the technical and regulatory requirements demanded by integrators, utilities, and industrial users.
NOM-K / CFE
NOM-K certification qualifies our transformers for use in CFE-regulated projects, public bids, and national energy infrastructure. It ensures alignment with CFE specifications, improving acceptance, reducing revisions, and positioning Delta as a certified national supplier.
Technology That Builds Continuity
Our technology is centered on precision engineering, certified processes, and full in-house design that ensure every transformer meets the highest international standards. From advanced manufacturing methods to rigorous FAT/SAT testing, we integrate traceability, quality control, and technical innovation at every stage. This is how Delta Electric transforms engineering into reliability—and reliability into continuity for the industries that cannot afford failure.
