Yichang 5.88 MWp Rooftop PV Box-Type Substations
Six YBM box-type substations for a rooftop distributed photovoltaic project, 2023.
For a 5.88 MWp rooftop distributed photovoltaic project in Yichang, we supplied six YBM box-type substations rated 1,250 to 2,500 kVA at 10/0.8 kV. Each unit steps the 0.8 kV inverter output up to 10 kV for grid connection.
Six PV box-type substations, 1,250 to 2,500 kVA, for one 5.88 MWp rooftop project.
Scope of Supply
1 × YBM-1250/10/0.8, 1,250 kVA
1 × YBM-1600/10/0.8, 1,600 kVA
3 × YBM-2000/10/0.8, 2,000 kVA
1 × YBM-2500/10/0.8, 2,500 kVA
A YB European-style box-type substation combines medium-voltage switchgear, a transformer and low-voltage equipment in one enclosure, which reduces site installation work.
How We Deliver Each 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.
