Product Description

S11 Oil-Immersed Silicon Steel Laminated Core Transformer

The S11 series three-phase oil-immersed distribution transformer features a precision-engineered silicon steel laminated core and corrugated rectangular oil tank. The fully sealed, conservator-free design isolates transformer oil from air, preventing oxygen and moisture ingress for extended service life with minimal maintenance.

Key Features

  • Corrugated Rectangular Oil Tank — Flexible corrugated panels compensate for oil volume changes without a conservator; fully sealed against moisture and oxygen
  • Precision Welding Technology — Full, smooth, and uniform welds for superior sealing and long-term reliability
  • Low-Height Core Design — Overall height lower than conventional transformers of equivalent capacity, saving installation space
  • Oil & Moisture Isolation — No-conservator sealed construction extends service life and reduces inspection frequency
  • Durable & Reliable — Robust tank structure with excellent mechanical strength for demanding environments
  • Customizable — Available in a wide capacity and voltage range; connection group, accessories, and cooling options configurable
