Transformers for Wind & Solar Farms
Box-type substations and transformers that collect renewable power and connect it to the grid.
A solar farm transformer steps the low-voltage output of PV inverters up to medium voltage for grid connection. We supply YB European-style and ZGS American-style box-type substations from 10 to 35 kV and 30 to 4,000 kVA, plus oil-immersed and dry-type transformers for auxiliary supply.
Six box-type substations supplied for one 5.88 MWp rooftop PV project in Yichang.
What We Supply
YB European-style box-type substations, 10–35 kV, 30–4,000 kVA
ZGS American-style box-type substations, 10–35 kV, 30–4,000 kVA
Oil-immersed and dry-type transformers for auxiliary supply
Our solar PV references include the Datang Lüsigang project, the Yanchang Petroleum project and the Yichang 5.88 MWp rooftop project.
How We Deliver Your Project
Every Yuantong project follows the same controlled process, from technical review to delivery.
01
Requirements & Design
We review capacity, voltage, standard and site conditions, then complete the electrical design with computerized design software and 3D structural modelling.
02
Manufacturing
Cores, coils and assemblies are produced in our Hai'an, Jiangsu factory, including silicon steel cutting, coil winding, vacuum casting and drying.
03
Factory Testing
Every unit is tested in our test hall and receives 100% inspection of appearance and function before release.
04
Packing & Delivery
Units are packed in export wooden cases and delivered by road in China or shipped by sea from Shanghai.
Standards & Quality
Our transformers are designed and built to international and Chinese national (GB) standards as specified by the customer. Our management systems are certified to ISO 9001, ISO 14001 and ISO 45001, and our low-voltage products hold CE attestation of conformity under the Low Voltage and EMC directives.
