Comking Power Unveils Advanced Medium-Voltage Solutions for Global Grid Modernization
Zhuhai Comking Electric Co., Ltd., a trusted innovator in power distribution technology, has expanded its international portfolio with three high-performance medium-voltage products designed to meet the evolving demands of smart grids and resilient infrastructure worldwide: the CKFZ-12 Indoor Vacuum Load Switch, the JDZW-10R Pole-Mounted Outdoor Voltage Transformer, and the CKWZ-12 Intelligent Outdoor Vacuum Circuit Breaker.
At the core of these solutions is Comking’s commitment to reliability and safety. Both the CKFZ-12 and CKWZ-12 leverage Vacuum bubble arc extinguishing technology—a proven method that ensures rapid, maintenance-free interruption of load and fault currents without fire or explosion risk. The CKFZ-12 indoor switch integrates the vacuum bubble within a solid epoxy-insulated cylinder, delivering stable insulation performance and compliance with “five-prevention” interlocking standards for safe operation in ring-main units and switchgear panels. Meanwhile, the CKWZ-12 outdoor circuit breaker combines this arc-quenching excellence with intelligent control, enabling remote operation, automation integration, and reclosing functionality—ideal for rural electrification, urban grid upgrades, and industrial facilities.
Designed specifically for harsh environments, the CKWZ-12 is a flagship offering in Comking’s 12kV outdoor power distribution equipment lineup. Its fully sealed, three-phase pillar structure features UV-resistant, anti-condensation epoxy resin insulation and a compact, lightweight design (just 100 kg) that simplifies installation on poles or substation platforms. With a rated short-circuit breaking capacity of 20 kA and a mechanical life of 10,000 operations, it delivers long-term performance even in humid or cold climates.
Complementing these switching devices, the JDZW-10R Pole Switch Outdoor Voltage Transformer provides accurate voltage measurement and protection signaling for Voltage 3~12kV outdoor power distribution equipment systems. Cast in epoxy resin and overmolded with silicone rubber, it offers superior pollution, moisture, and UV resistance—making it suitable for tropical and coastal regions. Available in multiple ratios (e.g., 10/0.1 kV) and accuracy classes (0.2, 0.5, 3P), it supports metering, protection, and automation functions without requiring routine maintenance.
