Frequently asked questions
What is the rated capacity of the 1500kVA Three-Phase Pad-Mounted Transformer (13.8kV to 400/230V, Loop Feed)?
The standard configuration is rated 1500 kVA at 50 / 60 Hz. Other ratings in the same family can be built to order — tell us the load and we will confirm the nearest standard rating.
What voltage ratio is available?
The standard unit is 13.8 kV / 34.5 kV input to 400V / 230V (415/440/480V optional) output. Voltage ratio, tapping range and vector group can be adjusted to your network; 50 Hz and 60 Hz designs are available.
Which standards and certifications apply?
The product is designed to IEC 60076, UL, CE. MARS operates an ISO 9001 / 14001 / 45001 certified factory and holds CE (ECM), UDEM, EAC and CQC approvals; every unit is routine-tested before dispatch and type or witnessed tests can be arranged.
Can this product be customised?
Capacity, voltage ratio, secondary voltage, feed configuration, enclosure color, and winding material can be tailored to project requirements.
What is the lead time and how is it shipped?
Typical lead time is 25–45 days after drawing approval for distribution equipment and 60–90 days for power transformers and containerised systems. Shipment is by sea from Shanghai on EXW, FOB, CIF or DAP terms with a full document pack.
