Armored mid-mounted metal-clad switchgear

Product Introduction

The armored mid-mounted metal-clad switchgear is constructed with cold-rolled steel plates, formed via CNC processing and assembled into a cabinet with armored compartmentalized structure, internally divided into independent circuit breaker chamber, busbar chamber, cable chamber, and relay instrument chamber. Suitable for 3.6kV-40.5kV AC three-phase 50Hz power systems, it is widely used in power distribution systems of power plants, substations, and industrial & mining enterprises, undertaking circuit control, protection, and monitoring tasks. Compliant with standards like GB 3906 and IEC 62271, it features high mechanical strength and stable electrical performance.

Product Features

Safe and reliable with "five-prevention" interlock, IP4X enclosure (blocking foreign objects/electric shock), and fast-switching breakers for quick fault cutoff. It has excellent insulation—high-quality materials resist high voltage, low partial discharge, adapting to harsh environments. Its compact structure (mid-mounted breaker, modular layout, vibration/impact-resistant cabinets) and smart adaptability (monitoring modules for real-time data, remote communication, fault warning) meet smart grid needs.

Product Classification

Classified by voltage level (3.6kV, 12kV, 24kV, 40.5kV) for different power system levels; by circuit breaker type (vacuum: strong arc extinguishing, low maintenance; SF₆: large breaking capacity for high-load scenarios); and by function (standard: basic power distribution control; intelligent: with condition monitoring and automatic control).

After-sales Service

Installation & commissioning: a professional team arrives within 48 hours to complete installation and relevant tests per specifications for compliant parameters. Training support includes manuals and on-site sessions to master maintenance/emergency skills. Fault response offers 7×24 hotline, on-site arrival within 2/4 hours (urban/suburban), and maintenance tracking. Spare parts guarantee: 6 national warehouses with common components delivered within 24 hours for quick replacement.
