Electrical Substation Components We Manufacture

Power and distribution transformers, HV switchgear, ring main units, vacuum circuit breakers and LV panels – the components of every distribution substation.

What Components Make Up an Electrical Substation?

An electrical substation is built from a defined set of components: transformers, HV switchgear, instrument transformers, circuit breakers, protection and LV panels. Sourcing them from one manufacturer keeps ratings, interfaces and documentation consistent.

Whether you build conventional or prefabricated substations, component quality and interface compatibility decide reliability. We manufacture the main components in-house and test them together.

  • In-house components – transformers, switchgear, RMU and breakers from one factory.
  • Interface consistency – ratings and connections engineered to work together.
  • 6-132 kV class – components for distribution and sub-transmission.
  • 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 Substation Components

We manufacture four component groups:

Transformers

Oil-immersed and dry-type units for substation duty.

Switchgear & RMU

KYN28A-12 switchgear and XGN15-12 / HXGN15-12 ring main units.

Circuit breakers

VS1 indoor and ZW32 outdoor vacuum circuit breakers.

Component Sets vs Individual Sourcing

Buying substation components individually from separate suppliers risks rating mismatches and divided responsibility. A coordinated component set from one factory is tested for compatibility.

We supply both loose components and coordinated sets – the choice depends on your procurement model.

よくある質問

Electrical Substation Components FAQ

Common questions about substation components and factory sourcing.

どのようなコンポーネントを製造していますか?
Power and distribution transformers, HV switchgear, ring main units, vacuum circuit breakers and LV panels.
Can you coordinate ratings across components?
Yes – our engineers confirm ratings, connections and protection coordination across the component set.
Do you provide type test reports?
Yes – type test reports are available for each component family.
最小注文数量とは何ですか?
Single components are available; project volumes receive the best factory pricing.
What is the difference between a power transformer and an instrument transformer?
A power transformer transfers energy and steps voltage levels. An instrument transformer – a current transformer or voltage transformer – feeds proportional measurement signals to protection relays and metering. Substations need both.
What are your delivery terms?
FOB / CIF / DDP terms are available, with lead times confirmed against your project schedule.
