Quality Management
We operate under ISO 9001:2015-certified quality management systems that are central to our manufacturing excellence.
NEC maintains dedicated ISO 9001:2015-certified Quality Management Systems at both of its factories — Brownsville, Texas, for the manufacture of new high-voltage stator coils, and Columbus, Ohio, for the manufacture and installation of new and refurbished field windings. NEC has long embraced a philosophy of complete customer satisfaction and continuous improvement.
We are proud to report that our Brownsville facility’s Quality Management System was first certified to ISO 9001 in 2005 by an independent, accredited certification body. View our current certificate for Brownsville. Our quality management systems help us systematically identify and document manufacturing deviations, investigate root causes, and implement corrective actions to prevent recurrence. We maintain a transparent and collaborative environment—customers are welcome to visit our facilities to monitor production activities, and related quality assurance records are readily available for their review
Daily Progress Reports on Installation Work
In addition to standardized Quality Inspection Process (QIP) documentation, NEC uses its daily report system to provide both its customers with up-to-date information of project progress. These concise reports, compiled by the project's lead quality inspector, include pictures and relevant comments about both the progress of the work and any related engineering, installation, schedule or safety issues. Additional comments, clarifications or updates from other team members may be added when our project managers transmit them to the customer's engineer-in-charge.
Active Link Between Quality & Innovation
Our quality management systems provide a framework of process management, data collection for our manufacturing innovations. One such innovation is the 900-degree Roebel transposition that NEC developed and implemented for certain stator bar designs. This Roebel assists greatly in reducing circulating current losses down to the lowest possible levels. But it is also a challenging manufacturing feat, and not all suppliers have implemented it as successfully as we have. And with these quality systems in place, we can also confidently manufacture a three-turn half coil with Kapton® and enamel strand insulation for another customer, even though it is a coil we don't make every day, or we can just as easily tweak a standard coil design to be more responsive to the spark erosion problems plaguing certain types of large air-cooled generators.
