Product Description:

S13 series transformer is a mainstream upgrading product for the current power grids and industrial power distribution systems. It is a new type of power transformer which combines economy and reliability. It has higher energy efficiency and lower operating losses than traditional S9 and S11 series transformers. It adopts high-permeability cold-rolled grain-oriented silicon steel core and high-purity oxygen-free copper wire winding, and is improved with the advanced processing technology and equipment, which makes it more energy-efficient than the S11 series, thus greatly reducing its total lifespan cost.

Normal Environmental Conditions：

The series transformer S13-M-10 can be operated stably for a long period of time under the following normal environmental conditions:

Maximum air temperature：

+40℃ Maximum daily average temperature

+30℃ Maximum annual average temperature

+20℃ Minimum temperature

-25℃ Ambient temperature

Altitude:

Max 1000m (customisation available for altitudes over this limit)

Ambient Humidity:

Relative humidity of 90% or less (at 25℃) with no severe condensation or corrosive gases

Installation Environment:

Outdoor, no flammable and explosive materials, no severe vibration and strong electromagnetic interference; can be installed on poles, platforms or inside transformer substations.

Power Supply：

Conditions Rated frequency 50Hz/60Hz Rated voltage 10kV Voltage fluctuation within ±5%

Mode of Operation:

Can work continuously under rated load for long time.

Model:

- S: Symbolises a three-phase transformer

- 13: Designation of performance level, an improved and optimised version of the S11 series with a no-load loss reduced by about 30% compared to the S11 series.

- M: The structure is fully sealed, adoption of corrugated tank fully sealed design, no oil conservator, isolating air and moisture, delaying insulation ageing.

- 10: Denotes a rated voltage level of 10kV, which is the most common voltage level in distribution network systems. Other voltages within the range of 6-11kV are possible.
