Urban distribution networks, ring-main power supply, cable branching, terminal distribution, and the high-voltage side of box-type substations
10kV distribution stations for residential communities, commercial complexes, industrial parks, and factories
Retrofit projects for outdated distribution systems, oil switch replacement
Frequent operation and load switching scenarios (e.g., transformer control, capacitor bank circuits)
Small-scale distribution projects where space and installation costs are sensitive
Structure Design:
Box-type metal-enclosed fixed structure, with metal partitions separating the busbar room, circuit breaker room, cable room, and metering room, enhancing safety with independent compartments.
Integrated Design:
The isolator, grounding switch, and main switch are integrated to simplify the internal layout.
Compactness:
The cabinet width is only 500mm, significantly saving space.
Manufacturing Process:
CNC laser cutting, CNC bending, and modular assembly, with little or no welding, ensuring high mechanical strength and precision.
Core Configuration:
Standard equipped with VS1 vacuum circuit breakers, rated current up to 1250A; includes complete mechanical interlocks and comprehensive protection interfaces.
Protection Level:
The shell has an IP3X rating, and internal compartments have an IP2X rating, meeting the safety requirements for indoor operation.
Production Standardization:
Modular design, high parts interchangeability, high production efficiency, and stable quality.
Installation:
Supports wall-mounted installation with front maintenance design, suitable for compact machine rooms and tight spaces.
Extremely Compact, Outstanding Economy:
The cabinet width is only 500mm, occupying about half the space of conventional switchgear, greatly reducing civil engineering and installation costs, offering high cost-performance.
Safe and Reliable, Complete Interlocks:
Features "Five Protection" mechanical interlocks, independent compartments to effectively prevent arc propagation; air insulation structure with no SF₆ environmental risks.
Convenient Maintenance, Stable Operation:
Fixed structure with clear zoning, no large-scale power outages needed for maintenance; front maintenance design with small operational space and high maintenance efficiency.
Strong Adaptability, Flexible Networking:
Compatible with mainstream circuit breakers, current transformers, and comprehensive protection devices; supports single bus, single bus sectionalizing, and is adaptable to various ring-main and terminal distribution schemes.
Environmentally Friendly, Long Service Life:
Free of toxic gases, long maintenance-free cycle; mechanical life ≥10,000 cycles, suitable for long-term stable operation.
