BUYER QUESTIONS

Direct technical answers.

Why is highest equipment voltage required?

It determines the applicable equipment class and insulation level; nominal system voltage alone is not sufficient for a final technical selection.

Can mounting steelwork and connectors be included?

Yes. Pole brackets, operating hardware, terminals and connection accessories can be coordinated when drawings and conductor interfaces are supplied.
