Description

On-Load Tap-Changing Laminated Core Transformer

S11 Series On-Load Tap-Changing Laminated Core Transformer

Product Overview

The oil tank adopts corrugated plate or expansion radiator oil tank, which does not need oil storage tank, thus reducing the height of transformer; the transformer oil does not contact with air, which prolongs the aging time of oil, and further prolongs the service life of transformer. The iron core is made of high-quality cold-rolled silicon steel sheet, adopting a fully mitered and perforation-free structure. The coil is made of high quality oxygen-free copper. Three-phase is fully sealed, and the performance conforms to GB1094 Power Transformer and GB/T6451-2008 Specification and Technical Requirements for Oil-immersed Power Transformers. It is widely used in transmission and distribution of urban and rural industrial and agricultural power grids.

Product Characteristics

Stable operation and high reliability.
Advanced performance level and reasonable economic index.
High production standard and wide application range.
Various forms of oil tank, beautiful and generous.
