Medium- and Low-Voltage Switchgear Manufacturer
Jinan Qinghe Electric designs and manufactures medium-voltage switchgear, low-voltage switchgear, switchboards and project-specific power-distribution assemblies for industrial facilities, data centers, utilities, commercial buildings, renewable-energy projects and EPC contractors.
Equipment configuration is developed from the approved single-line diagram, system voltage, load schedule, fault-current study, protection requirements and site conditions. Our engineering team coordinates switchgear interfaces with transformers, generators, transfer equipment and downstream distribution systems.
Medium-Voltage Switchgear Solutions
Medium-voltage equipment can be configured for incoming power, feeder protection, transformer primary distribution, motor loads and sectionalizing duties. Available solutions include project-specific metal-enclosed or metal-clad arrangements, circuit-breaker or load-break-switch configurations, protection relays, metering, interlocks and communication options.
Applicable voltage class, insulation level, short-circuit rating, bus rating, enclosure type and IEC or IEEE requirements are confirmed for each project. View our medium-voltage switchgear products.
Low-Voltage Switchgear and Switchboards
Low-voltage assemblies are available for main distribution, transformer secondary distribution, data center power systems, industrial plants and commercial facilities. Project options may include main and feeder circuit breakers, copper or aluminum bus, metering, surge protection, automatic transfer functions and indoor or outdoor enclosures.
Applicable North American low-voltage switchboards can be supplied within the covered UL 891 certification scope. Final listing, labeling and technical requirements are confirmed against the approved project configuration. View our low-voltage switchgear and switchboard products.
Engineering, Testing and Documentation
Each assembly is manufactured according to approved drawings and project specifications. Factory inspection and applicable routine testing can include visual and mechanical checks, wiring verification, insulation tests, functional checks, interlock verification and protection-control testing. Drawings, bills of material, test reports and export documentation can be supplied according to the agreed project scope.
