Why Can We Always Ensure Excellent Quality

Quality Control

Winley Electric holds a full range of third-party certifications widely recognized in North America, including UL, cUL, ISO, CE, TUV and EMC. With extensive experience serving the North American market, we are well familiar with ANSI/IEEE standards, utility requirements and local quality expectations.
Operating under a robust production management system certified to ISO 9001, we have implemented a complete material traceability system and formal supplier evaluation mechanism to ensure refined quality control throughout production.
Our factory conducts 100% routine testing for each unit before delivery, covering resistance measurement, ratio test, vector group check, applied voltage test, no-load and load loss measurement, and insulation resistance test.
In addition, we are equipped with professional facilities for full type testing as required by standards, including lightning impulse test, induced overvoltage test, temperature rise test, short-circuit withstand test, and partial discharge test. We can also perform customized type tests in accordance with client-specific requirements.
To offer additional assurance, we provide a 2-year free warranty service.
Backed by these strict quality control measures, Winley Electric has maintained an exceptional track record of zero critical quality issues for transformer products over the past decade, earning long-term trust from customers across North America.
