MV & LV Switchgear 0.4–35 kV

SWITCHGEAR

Switchgear and Distribution Equipment for Complete Power Systems

Yuantong builds KYN-series metal-clad withdrawable switchgear from 12 kV to 40.5 kV, GGD and withdrawable low-voltage switchgear, distribution boxes, ATS dual-power boxes and reactive power compensation devices. Supplied together with our transformers, they give you one source for the complete distribution system from medium voltage to the load.

FAQ

Switchgear FAQ

Can you supply switchgear together with transformers?

Yes. We supply MV switchgear, transformers and LV distribution as one package, so the interfaces match and you deal with one supplier.

What voltage levels does your switchgear cover?

Our range covers low-voltage switchgear at 0.4 kV and KYN-series medium-voltage switchgear for 12 kV, 24 kV and 40.5 kV.

Do you configure panels to our single-line diagram?

Yes. Send us the single-line diagram and equipment list, and we configure each panel and confirm the layout in our quotation.

What is your minimum order and lead time?

The minimum order is one panel. Lead time depends on the configuration; we confirm it in our quotation.

Which standards do you design to?

We design to IEC 62271, IEC 61439 or GB standards, or to the standard named in your specification.
