Product Description

Overview

S11 series is advanced designed to upgrade the former transformers in performance.

It has compact structure which requires a much smaller space to install. Its noise has been lowed down and capacity of overloading has been enhanced.
Comparing to S9 series, S11 series product decre

ased the loss of No-load by 30%. And current of no-load declined to 45-80%.
We have S11,S13, S20, S22 Serie transformers
 

Product Parameters

Main Characteristics:
1. Designed by patented technology and software with premium performance.
2. Core is made of high quality cold-rolled grain-oriented silicon steel sheet which produced in step-lap technology.
3. Winding is using high strength enameled wire or paper-insulated wire or copper belt, which offers uniform distribution of ampere-turns, reasonable insulation structure with high ability to withstand short-circuit.
4. Oil tank is corrugated type with high corrosion resistance. Tank surface pre-treatment liquid and coating powder adopts international top brands. The tank is degreasing, pickling, phosphorated, electrophoresis by automatic production lines, then power spray coating and heat-solidify.
5. The active part applies core free-hanging structure. The gasket is made of high-quality acrylate rubber which can inhibit ageing caused by sun and heat.

Advantages:
1. Low loss, low noise, low partial discharge, high reliability.
2. Safety with elegant appearance.
3.Corrugated oil tank, good cooling performance and flexible in shaping change while its heating.
4. Convenient installation and simple maintenance.
5. Compact with small occupied area.
high efficiency, low loss, low noise, strong load resistance and long service life.


Applications
1. Building Infrastructure and Industrial: Airports, hospitals, factories, shopping malls, hotels, commercial and residential towers.
2. Utility: Generation, transmission, distribution substations, water and waste water treatment plants.
3. Oil and Gas: Oil and gas plants, petrochemical plants and refineries.

Service environment:
1. Ambient temperature: Maximum +40ºC, Minimum -40ºC
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
