Complete Engineering Solution Scope

Project Scenario

Primary and secondary distribution networks, ring feeders, transformer substations, urban distribution rooms and network reinforcement projects.

Typical Challenges

  • Maintaining supply continuity and clear operating logic
  • Selecting compact equipment for restricted substations
  • Coordinating utility protection, metering, interlocks and remote signals

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 RMU for 10/11/12kV systems, QCL-24 GIS for 20/22/24kV systems, QCL-40.5 GIS for applicable 33–40.5kV projects, plus XGN15-12 AIS RMU.

Review QCL-12, QCL-24, QCL-40.5, XGN15-12 and YB-12.

Typical Configuration

Typical arrangements may combine ring cable units, breaker or fuse transformer protection, PT/metering and bus-section functions. Final functions follow the utility 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.
