Product Description

ZMT on load tap changer

General
ZMT OLTC is a kind of multi-level coarse and fine voltage-regulating OLTC specially designed for special
transformers with high voltage level, wide voltage range and large capacity.
The OLTC is widely used in the smelting industry, such as the electrolytic aluminum industry. Operate the
OLTC under load to change the tap position of the rectifier transformer winding (up to 107 positions), so that
the low voltage side voltage can be in a larger range according to the smelting process The requirements change
accordingly to produce high-quality products at competitive prices.
