XGN15-12 High Voltage Incoming Metering Cabinet & Outgoing Cabinet Combination

CHANGYUNZHINENG XGN15-12 Incoming Metering Cabinet & Outgoing Cabinet Combination – Product Introduction

1. Product Overview

The CHANGYUNZHINENG XGN15-12 series ring main units (RMU) are a new generation of metal-enclosed switchgear featuring SF₆ load switches as the main switching device and air insulation throughout the cabinet. Designed for AC 50Hz, rated voltage 12kV power networks, they are widely used in industrial and civil cable ring networks and power supply terminal projects. They are particularly suitable for urban residential distribution, small secondary substations, and switching stations.

This combined solution consists of an Incoming Metering Cabinet and an Outgoing Cabinet, forming a complete power receiving, metering, and distribution system – an ideal solution for urban and rural grid upgrade projects.

2. Incoming Metering Cabinet

The incoming metering cabinet handles the introduction and control of the main power supply, while integrating high‑precision energy metering functions.

Key Functions:

• Power input & control – Acts as the main incoming feeder for the switchgear assembly, equipped with a main incoming switch with visible disconnection points for safe maintenance.
• Energy metering – Integrates metering circuits to accurately measure electricity consumption, providing reliable data for billing.
• System control – Houses the control system for the entire assembly and main current transformers.

3. Outgoing Cabinet

The outgoing cabinet distributes power to individual load circuits, providing control and protection for downstream equipment.

Key Functions:

• Load distribution – Serves as branch units in the ring network, distributing power to various load feeders.
• Circuit protection – Equipped with comprehensive protection devices against overload, short‑circuit, and other faults.
• Flexible expansion – Modular design allows combination into multi‑circuit switchgear systems as needed.

4. Combined Advantages

The incoming metering cabinet and outgoing cabinet combination offers the following significant benefits:

1. Complete functionality – Forms an entire distribution chain from power entry, metering, to load distribution.
2. Compact structure – Cabinets are made of zinc‑plated steel sheets, processed by CNC machines and riveted, resulting in small footprint and light weight.
3. Safe and reliable – Features "five‑prevention" interlocks to prevent misoperation; protection rating IP3X.
4. Low maintenance – SF₆ switchgear has short arcing time and long mechanical life (load switch up to 5,000 operations), ensuring safe and reliable operation.
5. Flexible configurations – Can be arranged into different functional switchgear combinations according to primary design schemes to meet diverse requirements.

5. Technical Specifications

The CHANGYUNZHINENG XGN15‑12 incoming metering and outgoing cabinet combination delivers an efficient, safe, and intelligent distribution solution backed by advanced technology, reliable interlocking, and a compact design – the optimal choice for modern power distribution networks.
