JLSZV1-10/6/3 Three-Phase Dry-Type Combined Metering Box for 10kV Systems

Compact & Reliable Metering Solution for Three-Phase Three-Wire Networks

The JLSZV1-10/6/3 combined transformer is a dry-type metering box that integrates current and voltage transformers into a single unit. Designed for 10kV three-phase three-wire systems, this model delivers precise measurement for energy billing, monitoring, and protection, especially in outdoor or compact substations.

With a space-saving epoxy-cast housing, it simplifies installation and ensures long-term operation in industrial, rural, or utility grid metering applications.
