Substation Equipment for Texas and Oklahoma
Ryan Sales supplies the equipment inside the fence: power transformers and packaged substations, gas-insulated and metal-clad switchgear, outdoor breakers, station post insulators, high voltage cable terminations, sensors and line monitoring. We work with utilities, co-ops, EPCs and industrial owners across Texas and Oklahoma, and with data center substations nationwide.

Transformation. JST power transformers and medium voltage packaged unit substations, specified for your MVA, voltage and cooling class.
Switching and protection. Gas-insulated switchgear and ring main units when the footprint is tight, metal-clad switchgear and vacuum circuit breakers for indoor lineups, and outdoor substation breakers for the yard.
Bus and line support. ARP silicone polymer station post and line post insulators for bus supports and line exits.
Cable entry. G&W Electric Python terminations and joints for high voltage cable, including GIS and transformer terminations.
Visibility. Lindsey voltage and current sensors, transmission line monitoring and dynamic line rating for the lines leaving the station.
Specify the long-lead items first
Power transformers and switchgear set the schedule on most substation projects. Send us the one-line early and we will get current factory lead times and production slots before you lock the design. See our guide to medium voltage equipment lead times.
One rep for the package
Because we represent five manufacturers whose lines fit together, one Ryan Sales rep can quote the transformer, switchgear, insulators, cable accessories and sensors together, and stay with the job through submittals and startup.
Frequently asked questions
Who is a substation equipment rep for Texas and Oklahoma?
Ryan Sales represents JST Power Equipment, G&W Electric, ARP and Lindsey Systems for substation projects across Texas and Oklahoma: power transformers, packaged substations, gas-insulated and metal-clad switchgear, outdoor breakers, station post insulators, high voltage cable terminations and line sensors. Sales executives cover the Gulf Coast, Central and South Texas, North Texas and Oklahoma, and West Texas.
How long are substation transformer and switchgear lead times?
Wood Mackenzie's Q2 2025 survey put power transformers at about 128 weeks on average and switchgear at about 44 weeks. Because transformers and switchgear set the schedule on most substation projects, send Ryan Sales the one-line early to get current factory lead times and production slots before the design is locked.
What outdoor substation breaker does JST offer?
The JST OD3MAG is a 15.5 kV outdoor substation circuit breaker with recloser functionality for utility substations and solar and wind distribution. Ryan Sales supplies it in Texas and Oklahoma and on data center projects nationwide.
What insulators are used for substation bus support?
Ryan Sales supplies ARP silicone polymer station post insulators for substation bus support, switch bases and apparatus insulation. The ARP Station Post Series covers 7.5 kV to 69 kV.
Is there an SF6-free switchgear option for substations?
Yes. The JST J20N is a 38 kV SF6-free dry air gas-insulated switchgear for utility distribution substations and renewables interconnection. It keeps the compact footprint of gas-insulated gear without SF6.
