Seven product lines, all in-house: Oil-immersed transformers (up to 35kV, 10MVA), dry-type transformers (SCB10/SCB13, up to 3150kVA), ring main units (SF6 and solid-insulated), HV switchgear (KYN28, XGN, HXGN), LV switchgear (MNS, GCK, GGD, XL-21), package substations (European, American, E-House), PV combiner boxes (DC 1000V/1500V).
Oil-immersed: better cooling, higher overload capacity, lower cost, longer lifespan. Suitable for outdoor installation. Dry-type: no oil, flame-retardant, low noise. Suitable for indoor installation — commercial buildings, hospitals, data centers. Our recommendation: indoors or near people, go dry-type. Outdoors and cost-sensitive, go oil-immersed.
Any customer-specified voltage. Common: 6kV, 10kV, 11kV, 13.8kV, 20kV, 33kV, 35kV primary. 0.4kV, 0.69kV, 3.3kV, 6.6kV secondary. 50Hz or 60Hz. If your grid uses something unusual, send us the spec — we'll confirm.
IEC 60076 (transformers), IEC 62271 (switchgear). We also manufacture to ANSI/IEEE, BS, and GOST on request. ISO 9001, 14001, 45001 certified.
That's our default mode. We don't sell from a catalog — we build to your spec. Voltage, frequency, vector group, impedance, cooling method, enclosure material, IP rating, paint color, cable entry direction — all customizable.
