Mission

Provide humanized power equipment and service.

Vision

To become a first-class power equipment supplier.

Team

11–50 engineers and trade specialists based in Jiangsu, China — small enough to stay hands-on with every order.

Solutions

One point of contact, every part of the system.

As a solution provider — not a single-product factory — we scope transformers and storage together, so interconnection is designed in from day one.

GRID

Utility & Distribution

Distribution and power transformers sized to substation and rural-grid specifications, with OLTC where regulation is required.

SOLAR

PV & New Energy

Step-up transformers and containerized battery energy storage matched to solar and wind interconnection points.

SITE

Industrial & Commercial

Dry-type and special transformers for factories, data centers and buildings with tight footprint or fire-safety constraints.

OEM

OEM & Distribution Partners

Custom nameplate, private-label and volume-manufacturing programs for distributors and EPC contractors.

Contact

Tell us the voltage class and the site — we'll do the rest.

Send your single-line diagram or load requirement and our engineering team will return a technical proposal, not just a price sheet.
