Comking Electric Launches Integrated 12kV Indoor Switchgear Solutions for Global Wholesale
As global demand for safe, reliable, and compact indoor power distribution equipment rises, Comking Electric Co., Ltd. announces the integrated promotion of three core products in its 12kV indoor switchgear portfolio: the CKFZ-12 Indoor Vacuum Load Switch, the KVB-12 Indoor Vacuum Circuit Breaker, and the CXGN-12 Box-Type Fixed Indoor Switchgear —all available for global wholesale.
Modern indoor switchgear relies on vacuum technology for safe, maintenance-free opening and closing of circuits. Unlike older systems, vacuum interrupters offer faster arc quenching, longer life, and no fire or explosion risk—ideal for substations, factories, and commercial buildings.
Product Highlights
CKFZ-12 Indoor Vacuum Load Switch – Engineered for Ring Main Networks
Designed for 12kV, 50Hz three-phase systems, the CKFZ-12 Indoor Vacuum Load Switch is ideal for ring main units and terminal power supply applications in urban infrastructure. With a rated short-circuit breaking capacity of up to 20kA, it ensures stable operation even under demanding conditions.
KVB-12 Indoor Vacuum Sealing Circuit Breaker Supplier China – Built for Frequent Operation
Where frequent switching and robust fault protection are required—such as in substations or industrial motor control—the KVB-12 Indoor Vacuum Circuit Breaker delivers unmatched reliability. Available in fixed, front-mounted, and withdrawable configurations, it supports rated currents up to 4000A and complies with IEC 62271-100, GB 1984, and other international standards.
CXGN-12 Box-Type Fixed Indoor Switchgear – The Complete Enclosure Solution
To house these advanced switching devices, Comking offers the CXGN-12 Box-Type Fixed Indoor Switchgear—a metal-enclosed, IP3X-rated system featuring a C&G modular frame design. This switchgear integrates seamlessly with both the CKFZ-12 and KVB-12 units, providing:
Reliable mechanical interlocks between breaker, earthing switch, and door
Powder-coated corrosion-resistant finish
Flexible wiring schemes for fast deployment in prefabricated substations
Ideal for motor control centers and distribution rooms, the CXGN-12 enhances safety while reducing installation time.
Indoor Switchgear Opening and Closing
Beyond individual components, Comking Electric supplies complete product series—including ring main units, transformers, EV chargers, and digital automation platforms—enabling end-to-end solutions for smart grids and sustainable energy systems.
All three highlighted products are now available for wholesale, with customization options for voltage, current ratings, and control interfaces. Comking also provides technical support, certification assistance, and logistics coordination for international clients.
