FAQ

Questions buyers usually ask

Which substation format is appropriate?

Compact units suit repeatable distribution duties. Prefabricated modular rooms provide more equipment access and customization. Containerized E-Houses are used where transportable, integrated electrical rooms reduce site assembly.

Which standard should be stated in the RFQ?

Use the project or utility standard stated in the specification. Where it is not defined, send the destination, system voltage and application so the appropriate IEC or ANSI/IEEE basis can be proposed.

Are guaranteed values the same as the website values?

No. Website values are selection guidance. Guaranteed performance is stated in the approved technical data sheet and commercial offer.

What information helps Apex respond faster?

A single-line diagram, load data, voltage ratio, capacity, quantity, installation conditions, destination and required delivery date provide the best starting point.
