02 / EQUIPMENT SYSTEMS
Four equipment groups for distribution projects.
Start with the equipment family, then specify ratings, service conditions, accessories and required reports.

FIELD REFERENCE · INTEGRATED SUBSTATION03 / E-HOUSE & SYSTEM SOLUTIONS
Freeze E-House interfaces before fabrication.
Confirm the MV, transformer, LV, protection, auxiliary, HVAC, fire, cable and civil boundaries on the approved drawings and interface register.

04 / APPLICATIONS
Match equipment to the load and operating duty.
Process continuity, maintenance access, fault containment and future expansion affect the selected switchgear, transformer and E-House configuration.
- Manufacturing and process plants
- Renewable-energy collection systems
- Utilities and infrastructure
- Critical facilities

07 / TECHNICAL NOTES
Technical notes for tender and supplier review.
Practical reading on Chinese test reports, E-House scope, FAT, site conditions and handover.
GB/T 1094.11 and IEC 60076-11: checking a dry-type transformer report
Check the tested unit, test conditions and declared classifications against the dry-type transformer offered for the project.
GB/T 3906 and IEC 62271-200: the switchgear evidence a buyer should actually compare
Ratings are only the first line of the review. Service continuity, internal arc classification, partition design and the relationship between the tested panel and the offered lineup often decide whether a report is useful.
IEC 61439 design verification for an assembled LV switchboard
Connect the offered assembly to its design-verification file, then specify the routine-verification records required for each delivered switchboard.
Does IEC 62271-202 cover the complete E-House? A buyer’s scope check
IEC 62271-202 can be central to a prefabricated substation package, but it does not make every switchboard, transformer, auxiliary system and site interface compliant by association. Buyers need a boundary schedule that shows which standard governs each part.
08 / HJ-SKILL
Compare a GB reference with your target standard.
Enter the two standard numbers and project parameters. StandardBridge prepares a preliminary comparison and a supplier-question list.
Use the governing standards, tender documents and responsible engineer for final acceptance.09 / PROJECT ENQUIRY
Send your SLD, specification or BOQ.
HJATIS pre-sales will review the equipment scope and reply to the work email in your enquiry.
