$22000.00
Overview
Nelink SZ11 / SZ13 series on-load tap changing oil immersed transformer is a three-phase oil immersed distribution transformer equipped with on-load tap changer (OLTC). It can regulate output voltage under load without power interruption. Designed for 10kV / 35kV medium voltage and 0.4kV low voltage power systems. The core is made of high-quality grain-oriented silicon steel sheet. Windings are made of high-purity copper. Oil conservator on top for oil expansion. Suitable for areas with large voltage fluctuation, industrial plants, commercial buildings and urban distribution networks requiring stable voltage. Compliant with GB / T 6451 and IEC 60076 standards.
