According to our (Global Info Research) latest study, the global Vacuum OLTC market size was valued at US$ 651 million in 2025 and is forecast to a readjusted size of US$ 827 million by 2032 with a CAGR of 3.5% during review period.
Vacuum OLTC is a tap changer that uses vacuum as an arc extinguishing medium. It changes the effective number of turns of the transformer and adjusts the voltage ratio by leading out several taps in the transformer winding and switching from one tap to another through a vacuum tube without interrupting the load current. Its working principle is based on vacuum arc extinguishing technology, that is, in a vacuum environment, the arc can be extinguished quickly, thus realizing oil-free and pollution-free tap changer operation.
