Current Transformer (CT) Cabinets
-- Steady & Reliable Manufacturer --
Product Overview
Current Transformer (CT) Cabinets are the "Metering Hubs" of a facility's power system, specifically designed to house the transformers that step-down high-current feeds to a measurable 5A or 1A signal. At DSJ Electrical, our CT cabinets are engineered to meet the strict requirements of utility billing and internal energy monitoring. We provide a safe, organized enclosure where current transformers can be mounted around the main busbars without compromising the system's insulation. Our cabinets feature "Sealable" doors as required by utilities for revenue metering, and dedicated test switches that allow for meter calibration without interrupting the customer's power. We use high-accuracy CTs (Class 0.2s or 0.5s) that provide the precision needed for accurate billing and power quality analysis. Whether you are installing a "Service Entrance" meter for a new factory or sub-metering a large commercial office tower, DSJ CT Cabinets provide the organized, secure, and utility-compliant enclosure your metering system needs.

Introduction
The Current Transformer (CT) Cabinet line from DSJ Electrical Co., Ltd is where "Power Becomes Data." We recognize that in the modern economy, you cannot manage what you do not measure. Our introduction of this series focuses on "Measurement Accuracy" and "Installation Security." We utilize high-grade "Mu-Metal" cores in our CTs to ensure that the current signal is reproduced with minimal phase error and saturation. Our manufacturing process involves the use of standardized "CT Mounting Rails" that allow for easy adjustment to fit various busbar sizes.
Innovation at DSJ involves "Digital Metering Integration." Our CT cabinets can be supplied pre-wired with smart meters and cellular or Ethernet gateways, allowing you to upload energy data directly to the cloud. We prioritize "Safety and Access Control," with clear viewing windows for meter reading and "Lock-Out/Tag-Out" provisions for maintenance. At DSJ, we provide our CT cabinets in both indoor (NEMA 1) and outdoor (NEMA 3R/IP65) configurations, ensuring that your metering infrastructure is protected from the elements. We understand that accurate billing is critical for your project's financial health, which is why we only use "Revenue-Grade" components and utility-approved enclosure designs. Choosing DSJ means choosing the most reliable and transparent data interface for your electrical network.
