Coordinating Transformers and Switchgear: Why Short-Circuit Data Comes First

2026年10月29日

A transformer and its switchgear cannot be specified independently. Transformer impedance influences available fault current, voltage drop and motor-starting performance, while switchgear interrupting ratings and protective-device settings determine how faults are cleared. When equipment is ordered before the system study is mature, teams may di…

Transformer Test Documents Buyers Should Request Before Shipment

2026年10月26日

Transformer testing gives the buyer evidence that the manufactured unit matches the approved design and applicable standard. A list of pass results is not enough: the records must be traceable to the specific serial number, calibrated instruments and agreed test procedure. Document requirements should be written into the purchase specification b…

E-House Power Systems Bring Factory Integration to Remote Projects

2026年10月23日

Remote mines, renewable plants, oil and gas facilities and infrastructure projects often face limited skilled labor, difficult weather and compressed construction schedules. A prefabricated E-House moves much of the equipment installation, wiring and functional testing into a controlled factory environment. The module may contain medium- and low…

35 kV Oil-Immersed Transformers: What Buyers Should Lock Before Factory Design

2026年10月20日

A 35 kV oil-immersed transformer connects utility, industrial and renewable-energy systems across a wide range of capacities. Because each project has different network and site conditions, the factory design should not start from voltage and kVA alone. Clear technical data at the beginning reduces drawing revisions, protection changes and civil…
