How to use this guide
Five decisions stand between you and a equipment that works.

Typical quotation inputs include voltage level, rated current, short-circuit level, transformer capacity, circuit quantity, site environment, drawings and required documents.

Final configuration is confirmed from approved datasheets, single-line diagrams, cabinet arrangement drawings and project standards before production.

1. Which type

Factory-side work can include equipment assembly, secondary wiring, routine inspection, outgoing inspection, packing and document preparation according to the confirmed scope.

2. Spec & compliance

For outdoor or site-side equipment, clarify IP protection, corrosion environment, ventilation, foundation, cable entry and maintenance access during the RFQ stage.

3. Who you’re really buying from

JSGK supports project buyers with product selection, scheme confirmation, factory coordination and documentation for electrical distribution equipment orders.

4. Landed cost & logistics

Our team can prepare cabinet layouts, technical datasheets, inspection records and delivery documents according to the confirmed project scope.

5. After it lands

Send the product family, electrical parameters, quantity, project location and delivery schedule so the sales and engineering team can prepare a focused quotation.
