CLSR-12/24 Compact Solid Insulated Ring Main Unit (RMU)

Overview

Chuanli is a professional ring main unit manufacturer supplying high-quality CLSR-12/24 solid insulated RMU for 12kV-24kV medium voltage distribution networks. The CLSR-12/24 series is a new generation of compact solid insulated ring cabinet with a high level of operational safety, which is applied in the distribution network as the core unit of the distribution network. The main modular components of the equipment include circuit breaker and three-station isolation switch body, load switch and three-station isolation switch body, fuse tube, insulated bus and cable joint. All high-voltage live parts are cast with high-quality insulating materials. The vacuum interrupter, main circuit, insulation support, etc. are organically integrated into a whole to achieve a fully insulated, fully sealed, maintenance-free structure. At the same time, it also greatly reduces the insulation gap between switches, and observes the position state of the ground switch through an independent observation window each time to ensure the safety of operation overhaul and maintenance.

Model Meaning

Product Classification

According to the function in the system, it can be divided into incoming cabinet, outgoing cabinet, busbar cabinet, metering cabinet, PT cabinet, arrester cabinet and other powerEnergy unit, different functional units have different wiring schemes, usually represented by wiring schemes.

According to the main switch category of the configuration, it can be divided into load switch cabinet (referred to as C cabinet l), load switch fuse combination electrical cabinet (JaneCalled F cabinet), and circuit breaker cabinet (referred to as V cabinet).
