Key Features of CNMIBO Transformers
High Accuracy Measurement
CNMIBO transformers are designed to achieve superior accuracy classes (0.2, 0.5, 1.0), making them ideal for energy metering, load monitoring, and protection systems. This ensures that the measured current or voltage accurately reflects the real performance of the power network.
Durable and Safe Construction
Each transformer is engineered with epoxy-resin encapsulation, flame-retardant materials, and IP-rated enclosures to withstand challenging indoor and outdoor environments. This design guarantees long-term reliability, even under high temperature or humidity conditions.
Smart Integration Ready
CNMIBO transformers are compatible with modern IoT, SCADA, and smart metering systems, making them perfect for smart grids and digital power networks that require real-time monitoring and communication.
Custom Engineering Capabilities
MIBO’s R&D team provides customized designs according to client specifications — including primary/secondary ratios, core geometry, mounting styles, and insulation levels — to ensure seamless system compatibility.
