FAQ:

What makes WEIPU a leading connector manufacturer?

WEIPU has been dedicated to industrial connectors since 1996, with full independent R&D, in-house tooling, and strict quality control from design to production, ensuring global-level reliability.

Does WEIPU participate in industry standards?

Yes. WEIPU is a member of the National Electrical Appliances Standardization Technical Committees and participated in drafting the national connector standard GB/T 11918-2014.

Can the WF Series connectors be used in marine salt spray environments?

No. It should be specifically noted that Weipu's WS, WF, and WY series connectors are not suitable for marine salt spray environments. The salt spray in marine environments is highly corrosive, and the material and protection design of this series of products cannot resist such strong corrosive effects. Using them in marine environments will lead to rapid degradation of product performance and even failure.

What is WEIPU’s approach to quality assurance?

All products are independently developed and manufactured, with strict monitoring across every step—material selection, machining, assembly, and testing—to guarantee consistent performance.

Can WS Series Connectors be used in outdoor low-temperature environments?

Yes. With a temperature adaptation range of -40°C~+85°C, they can operate stably in extreme low-temperature outdoor environments, making them suitable for outdoor industrial facilities in cold regions.
