| D11-M 20(10)Kv Off-load Distribution Transformers |
 |
 Brief introduction
- 20Kv D11 single-phase transformers are off-load outdoor oil type transformers designed for areas with low annual power load.
- The product shortens power distribution radius thus reducing line loss during the transmission. The phase load unbalance can be readily controlled, voltage compliance rate improved, which effectively improve the power supply quality.
- The product is ideal for residential area, railway and street lightening, rural power grid, remote areas, scattered villages etc.

Features
- Pole-mounted installation, small size, high overload capacity, easy maintenance.
- Cold-rolled grain-oriented high-silicone-content steel, step-up lamination, low no-load loss, and low no-load current.
- First Grade oxygen-free copper, new windings structure.
- Hermetically sealed oil tank.
- Vacuum oil-filling technology.
- Low noise emission.
