Transformer & Switchgear Supply for EPC Projects
Project-Specific Equipment Supply for EPC Contractors
Qinghe Electric supplies project-specific transformers, compact substations, and medium- and low-voltage switchgear for EPC contractors, utilities, industrial owners, and engineering teams. We support projects from specification review and drawing confirmation through manufacturing, factory testing, export documentation, and shipment.

Equipment Scope for EPC Projects
Dry-Type Transformers
Cast-resin and VPI dry-type transformers are available as separate construction options for indoor, industrial, commercial, infrastructure, renewable-energy, and data-center applications. Capacity, voltage, winding conductor, cooling, enclosure, impedance, temperature rise, and applicable standards are confirmed against the approved project documents.
Oil-Immersed Power and Distribution Transformers
Oil-immersed transformers can be configured for utility, industrial, renewable-energy, and general power-distribution projects. The final design is based on the load, voltage ratio, vector group, impedance, cooling method, installation environment, accessories, and project specification.
Pad-Mounted Transformers
Pad-mounted transformers are available for underground distribution, industrial facilities, commercial developments, solar, energy-storage, and utility applications. Utility requirements, loop-feed or radial-feed arrangement, protection, cable entry, enclosure construction, and applicable certification scope must be confirmed before production.
Compact Substations
Compact substations can integrate medium-voltage switching, a transformer, low-voltage distribution, protection, metering, and auxiliary equipment in a factory-assembled package. The configuration is developed from the project single-line diagram and site requirements.
Medium- and Low-Voltage Switchgear
Switchgear and switchboard solutions can be coordinated with the transformer package to support system integration. Rated voltage, current, short-circuit rating, protection, control, enclosure, bus configuration, incoming and outgoing feeders, and governing standards are reviewed for each project.
Engineering and Project Coordination
Review of specifications, single-line diagrams, load data, and equipment schedules
Technical clarification and identification of missing project information
Preparation and confirmation of data sheets, drawings, and agreed project documents
Coordination of transformer, switchgear, protection, cable-entry, and interface requirements
Manufacturing, inspection, and applicable factory testing
Export packaging, shipping documentation, and delivery coordination
Standards and certification requirements confirmed by product model and project scope
