Related Evidence
Only verified project, FAT, packing, shipment and application evidence will be linked.
Project Scenario
Solar plants and battery-energy-storage systems need reliable collection, step-up and grid-connection distribution between inverter blocks, transformer stations and the point of interconnection.
Typical Challenges
Distributed generation blocks, changing operating conditions, protection coordination, compact outdoor stations and staged project construction.
Recommended Equipment
12kV, 24kV or 40.5kV RMU/GIS and medium-voltage switchgear, combined with prefabricated substation solutions where required.
Typical Voltage & Configuration
Typical configurations connect inverter or BESS transformer feeders to collector circuits, bus sections and grid outgoing feeders. Final ratings, protection and panel arrangement are confirmed from the approved SLD and project specification.
Engineering and Delivery Support
SLD Review
Feeder functions, busbar rating, protection and metering review.
GA Drawing
Panel lineup, dimensions, cable entry and foundation interface.
Technical Clarification
Project-specific deviations, options and document schedule.
Testing & FAT
Agreed inspection, functional checks and FAT documentation.
Export Packing
Protected packing and shipping-section planning for international delivery.

Send the SLD, voltage, fault level, current, quantity and installation conditions. Qiangchi will prepare a project-specific equipment recommendation.
Complete Engineering Solution Scope
Project Scenario
PV plants, BESS facilities, collector substations, inverter stations and grid-connection packages requiring coordinated MV collection and transformer interfaces.
Typical Challenges
- Multiple feeder collection and protection coordination
- Cable-intensive layouts and compact equipment rooms
- Grid-code documentation, SCADA signals, FAT and staged delivery
Typical Voltage
Common project classes include 10/11/12kV, 20/22/24kV and 33/35/36/40.5kV. The applicable equipment class is confirmed from the nominal voltage, highest system voltage, insulation level and project standard.
Recommended Equipment & Products
QCL-12, QCL-24 or QCL-40.5 GIS selected by collector voltage; YB-12 compact substations where packaged transformation is required.
Review QCL-12, QCL-24, QCL-40.5, XGN15-12 and YB-12.
Typical Configuration
Collector feeders, inverter or transformer feeders, bus section, metering/PT, protection and grid-connection interfaces are defined by the approved SLD.
SLD, GA Drawing & Technical Clarification
Qiangchi reviews the SLD, BOQ and specification, prepares a project-specific configuration and coordinates GA drawings, interface details, component schedule and technical clarifications before production release.
Manufacturing, Testing & FAT
Manufacturing follows the approved documents. Inspection and routine testing are completed according to the applicable product and agreed requirements. Customer or third-party FAT witness scope can be confirmed in the inspection plan.
Packing, Delivery & Handover
Equipment is prepared for export handling according to cabinet size, destination and transport method. Packing list, shipping marks, agreed test records and technical documents are coordinated before dispatch. Lead time is confirmed according to configuration and quantity.
