Transmission Substation Equipment We Manufacture
Power transformers up to 132 kV class, HV switchgear and vacuum circuit breakers for transmission and sub-transmission substations, with type test documentation.
What Equipment Does a Transmission Substation Need?
A transmission substation steps voltage between transmission and sub-transmission levels, or feeds regional distribution from the high voltage network. Its core equipment – power transformers, HV switchgear and breakers – must meet the highest reliability standards.
Transmission substation equipment operates at 66-132 kV class in our range, engineered for continuous duty, high fault levels and demanding utility specifications.
- 66-132 kV class – power transformers for transmission duty.
- HV switchgear & breakers – switchgear and vacuum circuit breakers for substations.
- 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。.
Main Types of Transmission Substation Equipment
We manufacture three equipment types for transmission substations:
電力変圧器
66-132 kV class units for grid duty.
HV switchgear
Metal-enclosed switchgear for substation control.
Vacuum circuit breakers
Outdoor and indoor breakers for fault protection.

Transmission vs Distribution Substation Equipment
Transmission substation equipment operates at higher voltage (66-132 kV in our range) with stricter fault and test requirements. Distribution equipment covers 6-35 kV with different duty profiles.
We manufacture both classes and confirm the right specification for your network position.
Choosing a Transmission Substation Equipment Manufacturer
Transmission equipment demands utility-grade type tests, documented materials and long-term reliability. Verify test evidence and reference deliveries to grid operators.
