KS9 Oil-Immersed Transformer for Mining Applications | High-Reliability Transformer

Introduction to KS9 Oil-Immersed Transformer

OKS9 Oil-Immersed Transformeris an advanced three-phase powertransformerdesigned specifically for mining applications. Thesetransformadoresare ideal for central transformer substations, mining stops, general wind bypass, and main wind bypass systems, particularly in areas that contain gas but lack explosive hazards. Thanks to their robust construction, these transformers are also well-suited for operation in humid environments.

The core of the KS9 transformer series is constructed from high-quality silicon steel slices with low-loss crystalline granules. This unique composition results in significantly reduced no-load losses, minimized no-load current, and remarkably low operating noise, enhancing overall efficiency and reliability in demanding industrial environments.
