LMZB(J)2-12 Current Transformer

Product Overview

LMZB(J)2-12 Current Transformer 12kV Indoor Single-Phase Epoxy Resin Type Epoxy resin casting bus type current transformer, is widely used for measuring current, electric energy and protective relaying in the electrical system with rated frequency 50Hz or 60Hz and highest voltage for equipment 12kV. The product has three secondary windings (one measuring winding & two protective windings or two measuring windings &one protective winding). Rated primary current is 1000-5000A and rated secondary current is 5A.

Feature

• Strong adaptability: Rated voltage 12kV, specifically designed for AIS (Air Insulated Switchgear) systems, perfectly meeting the needs of medium-voltage power distribution scenarios.
• High-precision performance: Adopting high-quality iron core and winding design, it features high-precision metering (e.g., class 0.2S) and reliable protection (e.g., class 5P20) functions, ensuring accurate current monitoring.
• Excellent environmental resistance: Resistant to ultraviolet rays, salt spray, and high-low temperature fluctuations, adaptable to harsh environments such as outdoors or humid conditions, with strong stable operation capability.
• Reliable structure: Using epoxy casting technology, it has high mechanical strength, protection grade up to IP67 and above, outstanding dustproof and waterproof performance, and prolonged service life.
• Easy installation: Conforming to standardized installation dimensions, no complicated debugging required, facilitating rapid deployment and reducing the operation and maintenance costs of power distribution systems.
