Product Q&A

Q:Do your high-voltage components comply with international standards like IEC?

Yes, all our products, including earthing switches and disconnectors, are designed and manufactured in strict accordance with IEC 62271 and GB standards. We conduct rigorous routine tests (insulation, resistance, and mechanical operation) on every unit before shipment to ensure maximum reliability and safety in your power system.

Q:Can you provide customized products based on our technical drawings?

Absolutely. We have a professional technical team that supports OEM and ODM services. Whether you need specific phase-to-phase distances, customized terminal connectors, or additional auxiliary switches and sensors, we can modify our designs to meet your specific switchgear requirements.

Q:Do you provide installation guidance or technical documentation?

Yes, we provide comprehensive technical support for all our clients. Each shipment includes detailed installation manuals, technical drawings, and test reports. If you encounter any challenges during site installation or commissioning, our engineers are available for online video consultations to guide you through the process.

Q:What is the typical lead time and your Minimum Order Quantity (MOQ)?

Our MOQ is 1 unit, making it easy for you to test our quality. For standard models, the lead time is usually 7-15 days. For large-scale projects or highly customized orders, the lead time is generally 25-35 days. We maintain a regular stock of core components to ensure rapid response to urgent maintenance needs.
