High Voltage Substation Equipment We Manufacture
HV power transformers, switchgear, ring main units and vacuum circuit breakers for substations up to 132 kV class – tested and documented for grid and industrial projects.
What High Voltage Equipment Does a Substation Need?
High voltage substations need transformers, switchgear, instrument transformers and breakers rated for the incoming voltage – in our range from 12 kV up to 132 kV class. Each item must meet strict test and safety requirements.
Sourcing HV substation equipment from one accountable manufacturer keeps interfaces consistent, documentation complete and responsibility clear – factors that decide project success.
- Complete HV set – transformers, switchgear, RMU and breakers.
- Up to 132 kV class – voltage classes for substation duty.
- Utility-grade testing – type test evidence for grid approvals.
- 50,000m²工場 – in-house winding, assembly and testing.
- 350人以上の従業員 – エンジニアリング、品質、輸出チーム。.
- OEM / ODM & 卸売 – カスタムブランディング、パッケージング、ボリューム供給。.

Complete HV Package vs Equipment From Separate Vendors
HV equipment interfaces matter – transformer impedance, switchgear ratings and breaker coordination must match. A single manufacturer tests the set together and stands behind the whole package.
For grid and industrial projects, package supply reduces approval time and commissioning risk.
Choosing a High Voltage Substation Equipment Manufacturer
Verify type test evidence for each HV family and the manufacturer’s integration capability. HV failures are expensive – documentation and testing deserve scrutiny.
