Are OEM and ODM services available?

Yes, custom tailored products, OEM, and ODM services are welcome.

What certifications does the factory hold?

The factory is ISO 9001 and ISO 14001 certified, and products hold KEMA and CNAS certificates.

How does the varistor protect the system?

It displays large resistance at normal voltage and immediately translates to low resistance during over-voltage to release energy and limit voltage.

AI-Powered supplier vetting

SummaryYueqing Wortai Electric Co., Ltd. is a China-based electrical and electronics supplier identified as both a trading company and manufacturer/factory. Its stated product scope includes electrical equipment and accessories such as fuse cutouts, surge arresters, insulators, fuse links, hotsticks, and cable grips. The supplier reports ISO 9001 certification, eight production lines, 21–30 R&D engineers, and 21–30 quality-control staff. It offers OEM services and states that it prioritizes quality and customer service. Export activity is established, with exports beginning in 2009 and coverage across multiple global regions. However, the provided information does not substantiate specific after-sales procedures, financial strength, patented or demonstrated innovations, or named customer cases. The supplier’s 2025 registration records also show virgin silicone products supplied to Vietnam, indicating activity beyond the listed electrical product range.

Supplier typeWORTAI is described as a Chinese industrial electrical equipment and accessories company. Official classifications identify it as both a trading company and manufacturer/factory, while associated-company information classifies the business as wholesale and retail. This indicates a mixed manufacturing and trading model rather than a purely production-focused supplier.

CertificationsThe supplier reports holding ISO 9001 certification for its management systems. This is explicit evidence of a recognized quality-management certification, although the provided slices do not state the certificate’s issue date, scope, or validity period.

Production capacityWORTAI reports a physical factory location, eight production lines, 21–30 quality-control staff, and 21–30 R&D engineers. It also states that off-peak lead time is within 15 working days and peak-season fulfillment takes one month, providing direct evidence of organized production and fulfillment capacity.

Customization capabilityThe supplier explicitly states that it provides OEM services worldwide, and its product range covers multiple industrial electrical components. This directly supports the ability to undertake customer-specific or OEM work, although the slices do not specify customization scope, tooling capability, minimum order requirements, or engineering procedures.
