Southern States EV2 GOAB switch, rebuilt to outlast the original.

The EV2 is one of the most common gang-operated air-break switches we see across the Southeast, and its bearing is the failure we see most. We rebuild it with a 316 stainless shaft, a machined brass lock nut, Viton O-ring seals, and sealed stainless bearings, all machined in our Palm Harbor shop. Ship us the bearing, ship us the switch, or have our field crew pull it and reinstall it. We do not sell new switches. We renew the one you have.

The switch

One of the most common GOAB switches we see across Florida.

The Southern States EV2 is a rotating air-break disconnect covering roughly 15 kV through 230 kV, in vertical and horizontal mount, single and three phase. It has been the default distribution and sub-transmission GOAB across the southeastern United States for decades, which is exactly why so many are now reaching the age where the bearing gives out.

The switch does its job so reliably for so long that the bearing gets no attention until it stiffens, binds, and locks. By then, removing it takes a 45-ton press and a new shaft. Caught early, it is a scheduled shop repair. Caught during an emergency switching operation, it is an outage and a safety event.

The good news is that the EV2 was built to be serviced. The bearing, the contacts, the linkage arm, and the gear operator are all discrete subassemblies, and every one of them can be rebuilt or replaced. On most bearings we receive, the cast steel housing is the single component that comes back serviceable, and everything inside it is renewed.

We machine the replacement parts ourselves, including the obsolete ones. A part the OEM no longer stocks does not stop the job.

The bearing

The bearing is the failure we see most.

The operating-shaft bearing seizes from corrosion, not wear, and it is the single most common reason an EV2 comes to our bench. A dried felt seal wicks moisture, an aluminum lock nut corrodes and packs its threads, and the carbon-steel bearing cage rusts. We rebuild it with a 316 stainless shaft, a machined brass lock nut, two Viton O-rings, and sealed stainless bearings, in a standard rebuild or an enhanced coastal upgrade.

Common questions

Southern States EV2 questions.

Can a Southern States EV2 switch be rebuilt instead of replaced?

Yes. The EV2 is built to be serviced. The wear items are the operating shaft bearing, the switch contacts, the linkage, and the gear operator, and every one of them is rebuildable or replaceable. On most units the cast steel bearing housing is reused and everything inside it is renewed. A switch that has seized, corroded, or arced is a rebuild candidate, not scrap.

Do you carry EV2 parts, or is it custom each time?

We machine EV2 replacement parts in-house in Palm Harbor: stainless shafts, brass lock nuts, rain shields, and the full upgraded bearing assembly. Where an EV2 part is obsolete or the OEM no longer stocks it, we reverse-engineer it from a sample, a drawing, or a model number and machine it to specification. Send a model number and we respond within one business day with availability and lead time.

Can you remove and reinstall the switch, or do I ship you the bearing?

Either way. Ship us the bearing or the switch and we return it rebuilt, tested, and documented. Or our field crews across Florida and the Southeast remove the switch, we rebuild it in the shop, and the same crew reinstalls it as one scope. For gear operators worn or seized alongside the switch, our UGOR program replaces them on site.

Send the model number and the condition.

We respond within one business day with a scope, a price, and a lead time. Photos of the bearing, the shaft, and the operator help us scope it accurately. A stiff bearing caught now is a shop repair, not an outage.
