Product Description
JZ Series Online OLTC On-Load Tap Changer Oil Filtration Plant

OLTC transformers regulate the system voltage while the transformer is under energy. They regulate the low and high voltage so they prevent the negative effects of voltage variation.

OLTC transformers do not require maintenance for long time by using online oil treatment machine .

JZ Series Online OLTC On-Load Tap Changer Oil Filtration Plant is mainly used to cycle oil from bypass of the transformer and high voltage switch on line. It can remove moisture and tiny particles to keep oil clean and water content, flash point, breakdown voltage, cleanness of the oil will not go worse.

JZ Series Online OLTC On-Load Tap Changer Oil Filtration Plant Feature:
Work online with on-load working transformer or high voltage switch
The filter with high quality material can remove moisture from oil.
Remove tiny particles by the high quality filters, cleanness up to NAS grade 6.
