Fire-Safe Current Sensing for Urban Power Systems
Our Dry Type Current Transformer offers a completely oil-free design for maximum safety. This unit covers voltage levels from 10kV to 40.5kV. It uses epoxy resin as the main insulation material. This material provides excellent fire resistance and explosion protection. There is no oil leakage risk whatsoever. This feature makes the transformer ideal for city centers and underground distribution rooms. It also works well in commercial buildings with strict fire codes. The cast coil structure encases primary and secondary windings securely. This construction gives high mechanical strength and strong pollution resistance. Our factory handles every production step in-house. We have laser cutters and CNC bending machines for sheet metal. We also have APG epoxy casting equipment and a dedicated partial discharge lab. This complete production chain lets us control quality at every stage. We can also adjust production schedules flexibly to meet delivery deadlines.

Wide Selection for Different Applications
This Dry Type Current Transformer offers primary current ratings from 30A to 2500A. You can select the best ratio and capacity for your actual line load. The unit handles short-time thermal currents of 20kA for 4 seconds. This capacity handles common short-circuit events in distribution networks easily. We offer both metering class and protection class configurations. Metering versions serve revenue-grade energy accounting. Protection versions detect fault currents for relay systems. The external insulation design works for both indoor and outdoor use. This versatility makes the product suitable for many installation scenarios. Our customers use this transformer in substations, industrial plants, and commercial complexes. The product adapts to various operating environments without performance loss.

Strict Quality Control with Full Traceability
Every Dry Type Current Transformer goes through our dedicated partial discharge screening room. We run strict partial discharge tests before shipment. We also perform error tests to confirm accuracy. Our testing standards are often tighter than national requirements. We know that small insulation defects can become major failures over time. That is why we test every unit carefully. Our quality team creates an independent inspection file for each transformer. This file records all test results for future reference. If you have special design needs, our technical team welcomes custom requests. We discuss your specific requirements and propose feasible solutions. We believe that strict quality control builds long-term trust. The LZZW series is our flagship dry-type product. It delivers reliable performance in demanding applications. Our 12-month warranty gives you added peace of mind with every purchase.
