Product Overview
Rockwill RBM Type 11kV Outdoor CT PT Combined Metering Unit is a high-reliability power metering device specifically engineered for power grid metering applications. As a core product of Rockwill—an international one-stop power distribution equipment manufacturer—it integrates two key components: combined transformers and watt-hour meters. The combined transformer consists of 2 or 3 single-phase voltage transformers and current transformers, using 25# special transformer oil as the insulation medium, with primary and secondary terminals mounted on a single panel via porcelain bushings for enhanced safety and durability. Suitable for 3-phase, 50Hz power grids with rated voltages ranging from 6kV to 40.5kV (focusing on 11kV applications), this outdoor metering unit fully complies with relevant IEC/ANSI international standards, making it an ideal choice for global power grid operators, contractors, and bulk procurement projects.
