30kVA~1000kVASingle-Phase Transformer | Customization Available Upon Request

Honway Power's single phase oil immersed transformer range covers rated capacities from 30kVA to 1,000kVA across primary voltages of 6kV, 10kV, 11kV, 13.2kV, 13.8kV, 14.4kV, 22kV, 33kV, and 35kV — with secondary outputs from 0.1kV to 0.48kV configurable to your grid standard.

Manufactured at our 20,000 m² Shijiazhuang production facility with 21+ years of transformer engineering experience, every single phase oil immersed transformer we produce is built to IEC 60076 (for international and Asian/African/European markets) or ANSI C57.12.00 / C57.12.20 (for North American and export markets), with full factory routine testing and signed test report included as standard.

We supply utilities, EPC contractors, rural electrification project developers, and B2B distributors in 40+ countries. MOQ is 1 unit — OEM and custom orders accepted across the full capacity range.

Single-Phase Oil-Immersed Transformers 

ANSI vs IEC — Which Configuration Do You Need?

This is the single most important question buyers sourcing a single phase oil immersed transformer internationally need to answer before requesting a quote. Getting it wrong means a unit that cannot be connected to your grid infrastructure.

Choose IEC 60076 Configuration if:

• Your country operates a 50Hz grid (most of Asia, Africa, Europe, Middle East, South America)
• Your distribution line voltage is 10kV, 11kV, 22kV, 33kV, or 35kV
• Your secondary distribution voltage is 220V, 230V, 240V, 400V, or 415V
• Your project specification references IEC, BS, or equivalent national standards

Choose ANSI C57.12.20 Configuration if:

• Your country operates a 60Hz grid (USA, Canada, Mexico, most of Caribbean, Philippines, parts of Japan and Latin America)
• Your distribution line voltage is expressed as 7.2kV, 7.96kV, 13.2kV, 13.8kV, or 14.4kV
• Your secondary voltage is 120/240V split-phase, 240/480V, or commercial voltage like 277V
• Your project specification references ANSI, NEMA, or IEEE standards
• You need hanger brackets conforming to ANSI standard pole-mounting dimensions

Honway Power manufactures both configurations in full. Specify your grid standard and primary/secondary voltage in your enquiry — our engineering team will confirm the correct unit configuration within 24 hours.

Applications & Export Markets

Honway Power's single phase oil immersed transformer range is in active service across the following sectors and markets:

Rural Electrification — Africa Pole-mounted 10kV and 33kV primary units for World Bank and AfDB-financed rural electrification programs in Kenya, Nigeria, Tanzania, Uganda, Ethiopia, Ghana, and Mozambique. IEC 60076 compliant, with third-party inspection facilitated as required by tender conditions.

Rural Electrification — South & Southeast Asia 11kV and 33kV primary units for Bangladesh Rural Electrification Board (BREB), Nepal Electricity Authority (NEA), and rural distribution co-operative programs in the Philippines, Indonesia, and Vietnam.

North American Overhead Distribution 60Hz ANSI C57.12.20 configuration units for distributor partners in Mexico, Central America, the Caribbean, and US export projects requiring Chinese-manufactured alternatives to domestic ANSI-grade units.

Agricultural Irrigation Infrastructure Dedicated 10kV / 0.4kV pole-mounted units for irrigation pump station clusters in Pakistan, India, and Egypt, where a single single phase oil immersed transformer per pump reduces MV infrastructure cost versus shared three-phase distribution.

Railway Electrification 25kV single-phase traction supply transformers for overhead contact system (OCS) power supply on new-build electrified railway lines in developing markets — including sub-transmission level primary inputs and traction voltage secondary outputs.

Why Specify Honway Power for Your Project

21+ Years of Single Phase Transformer Manufacturing Our engineering team has deep experience with the specific technical requirements of single-phase distribution: CSP protection coordination, ANSI vs IEC configuration differences, high-altitude derating, tropical climate coating, and split-phase LV configurations for North American markets.

Proprietary Technology — CNIPA Patent ZL 2020 2 1536485.3 Our granted utility model patent for the HV winding fixing device — developed and applied across our production line — directly improves winding mechanical stability under short-circuit impulse forces, addressing a primary failure mode in rural distribution service where fault clearance times are long and fault current impulse stresses are repeated.

128+ Industry Certifications, ISO 9001 Certified Factory Our quality management system is third-party certified. Every unit is tested and documented before shipment, with full factory routine test report issued as standard.

Hebei Province Specialized & Innovative SME — Government-Recognised Technical Capability Recognised by Hebei provincial government as a technology-based enterprise (Cert. No. SKX202508A2050001), Honway Power operates to a higher technical standard than trading companies or assembly-only factories.

Third-Party Inspection Available For projects requiring independent quality verification, we coordinate SGS, Bureau Veritas, or TÜV Rheinland inspection and witnessed testing. Standard procedure for World Bank / AfDB-tendered rural electrification supply contracts.
