Durable LZZBW-10(1Outdoor Current Transformer - China Suppliers & Factory for 10kV/12kV Power Distribution
This outdoor current transformer serves as a multifunctional interface between high-voltage power lines and low-voltage monitoring equipment. Its primary role is to accurately sense and convert primary currents into standardized, isolated secondary signals for various downstream applications. It delivers high-precision signals (0.2S class) for revenue metering and energy analytics, supplies reliable measurement data (0.5 class) for system monitoring instruments, and provides two independent protection-grade outputs (10P class) to enable redundant or separate relay protection circuits, thereby enhancing overall grid safety and fault response.
Engineered explicitly for harsh outdoor conditions, the LZZBW-10(12) is ideally suited for applications in exposed medium-voltage distribution systems. It is commonly installed in pole-mounted switchgear, outdoor substation yards, and as part of renewable energy grid connection points for solar or wind farms. Its design is particularly advantageous for high-altitude installations, operating reliably at elevations up to 3500 meters, making it a robust choice for power distribution projects in mountainous, coastal, and other challenging geographical locations.
Integrates four distinct functionalities — precision metering (0.2S), system measurement (0.5), and dual protection (10P/10P) — within a single compact device, significantly simplifying system design, reducing footprint, and lowering installation costs.
The high-grade outdoor epoxy resin casting provides a fully sealed, monolithic insulation body with excellent resistance to moisture, UV radiation, pollution, thermal cycling, and mechanical impact, ensuring a long service life with minimal maintenance.
Certified for reliable performance at altitudes ≤3500 meters, addressing the specific insulation and performance challenges of mountainous and plateau power grid applications.
Offers exceptional versatility with a wide primary current range (5~1500A) and selectable secondary outputs (5A or 1A), accommodating diverse load profiles and simplifying inventory management for various project requirements.
Manufactured in strict accordance with GB20840.1 and GB20840.2, guaranteeing adherence to rigorous national standards for safety, performance, and reliability.
