Product Overview

SRM-12 is a 12kV gas-insulated RMU for 6kV and 10kV medium-voltage distribution systems. It is commonly used for urban and rural distribution systems and compact substations, with the final selection based on rated data, drawings, and site conditions.

EPC companies, electrical contractors, utility project teams, panel builders, and industrial buyers can request configuration review for sealed modular RMU configuration. Please send single-line diagram, rated voltage, rated current, short-circuit level, protection scheme, busbar arrangement, and cabinet layout, quantity, destination, and any project standard requirements for quotation.

Key Features

01

Safe Switching

SRM-12: The cabinet scheme can be reviewed for rated voltage, rated current, short-circuit level, interlocking, and protection requirements. This point is especially relevant to sealed modular RMU configuration.
02

Flexible Configuration

Incoming, outgoing, metering, busbar, and protection arrangements can be matched to the project single-line diagram. For SRM-12, check this together with the selected project scheme.
03

Utility Project Fit

The equipment is suitable for distribution rooms, substations, cable networks, and infrastructure power systems. On SRM-12, confirm the application duty, site layout, and project standard before selection.
04

Drawing-Based Selection

Cabinet width, depth, cable trench, busbar interface, and foundation details should be confirmed from project drawings. Use the SRM-12 drawings and rated data to confirm this point before quotation.
05

Maintenance Planning

Access, isolation, grounding, and operation sequence requirements can be reviewed before quotation. For SRM-12, review this with sealed modular RMU configuration and the final installation plan.
