Data Center Medium Voltage Equipment: One RFQ for the Whole MV Package
From the utility interconnect to 480 V, Ryan Sales quotes the medium voltage equipment for data center campuses anywhere in the U.S.: JST substation transformers, SF6-free gas-insulated switchgear, metal-clad lineups, pad mount and dry type transformers and battery storage, plus G&W Electric switching, protection and cable accessories. Send one request; one rep handles the package.
One request for the whole medium voltage package
Most data center RFQs go out one product at a time: a transformer inquiry to one vendor, switchgear to another, pad mounts to a third. Ryan Sales represents JST Power Equipment and G&W Electric, whose lines cover the medium voltage path from the utility interconnect down to 480 V, so one request to one rep can cover the substation transformer, the main MV switchgear, the step-down transformers, battery storage and the cable accessories that tie them together. You deal with one application contact, and purchase orders still go directly to each factory.
This page is the working version of our data center industry overview: what one RFQ can cover, what to send, and what happens after you send it. For the engineering background, read Medium Voltage Equipment for Data Centers.

How the RFQ works
A one-line, equipment list or spec is ideal. A rough list by voltage and kVA works too. Need an NDA first? Sign our mutual NDA online when you submit.
A rep checks ratings, fault duty, BIL and options against the factory data, and asks the questions that avoid a re-quote.
We return pricing and the current factory lead time and production slot for each item, so your schedule rests on real dates.
We stay involved through submittals, delivery, installation questions and energization.
What to send for a fast, accurate quote
- Utility service voltage and the on-site distribution voltage (commonly 13.8–34.5 kV)
- Transformer MVA or kVA, primary and secondary voltages, impedance, cooling and tap changer preference
- Switchgear bus arrangement, continuous current, fault duty and whether SF6-free is required
- Redundancy topology (N+1, 2N) and the number of power blocks or buildings
- Indoor, outdoor or harsh-environment placement for each transformer
- Project location, end user, required on-site dates and any owner specifications
Why the RFQ should go out early
Transformers and switchgear set the schedule on most data center builds. Wood Mackenzie's Q2 2025 survey put average power transformer lead times at 128 weeks and switchgear at 44 weeks (reported by POWER, January 2026). We do not quote delivery dates on this page; we get the current factory figures for your configuration and tell you what they are. Our lead-time guide tracks the published market data.
Nationwide, with factory access
Utility, co-op, industrial and contractor work at Ryan Sales is focused on Texas and Oklahoma. Data center projects are different: we take them anywhere in the United States, working with developers, EPCs and electrical engineers wherever the site is. Ryan Sales is also a WBENC-certified women-owned business, which can help owners meet supplier diversity goals when they buy through us.

Frequently asked questions
Does Ryan Sales quote data center projects outside Texas and Oklahoma?
Yes. Ryan Sales takes data center projects anywhere in the United States. Utility, co-op, industrial and contractor work is focused on Texas and Oklahoma, but data center developers, EPCs and engineers can send a one-line from any state and a rep will quote the medium voltage package.
Can one RFQ include equipment from more than one manufacturer?
Yes. The quote form lets you add as many items as you need from JST Power Equipment, G&W Electric, Richards MFG, Lindsey and ARP in one request. One rep coordinates the quotes, and purchase orders go directly to each factory.
Can we sign an NDA before sharing the one-line?
Yes. Tick “NDA required?” on the quote form and a Ryan Sales mutual NDA opens for electronic signature before you submit. A signed PDF copy is attached to your request.
Should the main switchgear be gas-insulated or metal-clad?
Gas-insulated switchgear saves floor space; JST's J20N dry air GIS takes up to 75% less space than air-insulated gear and uses no SF6. Air-insulated metal-clad gear such as the J100CLAD avoids insulating gas entirely and suits 5–15 kV lineups. The choice depends on voltage, fault duty, footprint and the owner's SF6 policy, which is why we ask for those details with the RFQ.
What does Ryan Sales need to quote a data center MV package?
Ideally a one-line and equipment list. Otherwise: service and distribution voltages, transformer kVA or MVA and voltages, switchgear bus arrangement and fault duty, redundancy topology, indoor or outdoor placement, project location and required dates. Partial information is fine to start; a rep will ask for the rest.
