Frequently Asked Questions

Q: Are you a factory or a trading company?

A: We are a factory, located in Ulinkcon Industrial Park, Bao'an District, Shenzhen, China.

Q: Who is responsible for customs clearance? Do you provide the necessary documents?

A: We provide complete customs clearance documents, including the commercial invoice, packing list, bill of lading, and certification reports. Customs clearance fees and duties are borne by the buyer (EXW/FOB terms). We can assist with document preparation if needed.

Q: What is rated current?

A: Rated current, also known as operating current, is the current at which the connector can work properly under its rated voltage. During the aviation plug design process, the connector's thermal design is engineered to meet the rated current requirement. As current flows through the contacts, heat is generated due to conductor resistance and contact resistance. When the heat exceeds a certain limit, the plug's insulation may be damaged, and the surface coating may soften and become exposed, resulting in failure.
