What Is This Product? – It Measures High Voltage Energy for Utility Billing
A High-Voltage Metering Cabinet is installed on the user's incoming side or in front of a transformer.
Inside, we put voltage transformers (PT), current transformers (CT), and a kWh meter to measure power usage accurately.
Rated voltage is 12kV to 40.5kV.
Accuracy class: active power 0.2S/0.5S, reactive power 2.0.
This product meets GB/T 16934 and DL/T 593.
The cabinet is usually installed next to the incoming and outgoing cabinets.
It is widely used in industrial and commercial buildings, substations, and renewable energy projects.
The site substations of China Railway and China Railway Construction use our High-Voltage Metering Cabinet for utility billing.

FAQ
What Materials and Processes Do We Use? – Fully Insulated and Sealed with Anti-Tamper Design
The cabinet is metal-clad. The metering compartment is separate from other compartments and sealed with lead or a special lock to prevent unauthorized opening.
The PT and CT are epoxy cast with high insulation levels.
Secondary wires use shielded twisted pair cables with anti-tamper terminal boxes.
The door has a viewing window to read the kWh meter clearly.
Busbars are fully insulated with heat-shrink tubing to avoid creepage.
Cabinet protection rating is IP4X.
We can add a prepaid meter and a remote trip interface.
Our factory is 2,000 square meters with ISO9001 certification.
