ZW32-12 Outdoor Vacuum Circuit Breaker
Outdoor feeder switching and protection for 12 kV-class overhead distribution networks. Manual or motorized operation, protection and control interfaces are selected per project.
ZW20-12 Boundary Vacuum Circuit Breaker
Boundary and sectionalizing protection for distribution feeders. CT/VT, controller, communication and reclosing requirements follow the confirmed protection philosophy.
Box-Type Switching Station
Outdoor enclosure-based switching and cable distribution for utility, industrial, campus and infrastructure applications, configured from the approved SLD and feeder schedule.
Cable Branch Box
Outdoor cable branching and sectionalizing arrangements selected by voltage class, cable interface, circuit quantity, insulation method and environmental conditions.
Outdoor Distribution Box
Stainless-steel or project-specified enclosures for low-voltage distribution, metering, control and auxiliary power applications.
Project-Configured Assemblies
OEM and EPC configurations with GA drawing, SLD coordination, component schedule, inspection records and export packing support.
Selection by Application
| Application | Typical Requirement | Recommended Direction |
|---|---|---|
| Utility overhead feeder | Switching, sectionalizing, protection and remote-control options | Outdoor VCB with project-selected controller and instrument transformers |
| Transformer boundary | Fault isolation, metering and protection coordination | Boundary VCB configuration based on protection study and utility rules |
| Industrial or mining network | Outdoor incoming/feeder switching under defined environmental duty | Outdoor breaker or enclosure-based switching station |
| Solar or BESS project | Collector feeder switching, auxiliary distribution and SCADA interface | Project-specific outdoor switching and control configuration |
| Campus and infrastructure | Cable branching, sectionalizing and compact outdoor installation | Cable branch box or box-type switching station |
Information Required for Selection
Electrical System
Rated voltage, frequency, neutral/earthing method, fault level and applicable standard.
Protection & Control
Relay functions, CT/VT data, metering, reclosing, communication protocol and remote operation.
Mechanical Interface
SLD, cable size and termination, mounting arrangement, enclosure material and ingress protection requirement.
Service Conditions
Altitude, ambient temperature, humidity, pollution, salt fog, wind, ice and seismic requirements.
Project Deliverables
Datasheet, GA drawing, schematic, terminal plan, component list and agreed inspection documentation.
Commercial Scope
Quantity, project stage, delivery destination, packing requirements and required document language.
Engineering rule: final ratings, insulation level, interrupting duty, enclosure degree, controller functions, dimensions and accessories are confirmed only in the approved technical agreement and drawings.
Engineering, Testing & Delivery
SLD & Configuration Review
We review the system arrangement, feeder duty, protection philosophy and interfaces before final model selection.
GA & Technical Submittal
Project-specific outline, interface and technical documents are prepared after configuration confirmation.
Inspection & FAT
Routine inspection and agreed FAT checks can be coordinated for confirmed orders.
Export Packing
Equipment protection, marking, document packing and loading arrangements are coordinated for the shipment scope.
EPC Support
Technical clarification, document schedules and interface coordination support project procurement and approval.
After-Delivery Support
Installation guidance and technical clarification are provided against the approved drawings and project records.
Frequently Asked Questions
What data is needed for an outdoor circuit-breaker proposal?
Provide voltage, current, short-circuit level, frequency, SLD, protection functions, CT/VT requirements, control voltage, communication needs, service conditions and quantity.
Can manual and motorized operation be selected?
Yes. The operating method and control interfaces are selected according to local-operation and remote-control requirements.
Can a controller and communication interface be configured?
Project-specific protection, measurement, reclosing and communication requirements can be evaluated against the confirmed specification.
Are outdoor dimensions and enclosure ratings fixed?
No. Dimensions, mounting and protection degree depend on the equipment type, interfaces, accessories and environmental duty.
Can Qiangchi support EPC and OEM projects?
Yes. Configuration review, drawings, technical submittals, inspection coordination, branding and export documentation can be discussed for confirmed project scope.
Can FAT and packing evidence be provided?
Agreed inspection, FAT documentation and export-packing records can be coordinated for confirmed orders.
