Product Description

Overview

S(B)11/13/20/22
Fully sealed oil immersed transformer

 

Product Description

Capacities from 30kVA to 5500kVA
 

Features:

1. Voltage level: 10~35/0.4kV
2. Capacity: 30~3150kVA
3. With silicon steel laminated iron core, three-phase balance, no third harmonic.
4. Significant reduction in no-load loss and no-load current, with excellent energy saving effect.
5. Fully sealed oil tank and vacuum oil injection technology prevent oil aging, no oil leakage, and maintenance free.
6. External corrugated heat sink for oil tank, good heat dissipation and adjustable oil volume change, no need to install oil storage tank.
7. The high and low voltage leads are soft connected, equipped with pressure release valve and temperature measuring device to ensure the safe operation of the transformer.
8. High ignition point oil can be filled according to user's requirements, safer and more reliable, with a long service life.

Range of application:
Suitable for urban and rural power grid construction and renovation projects, as well as other distribution engineering projects, such as high-rise buildings, densely populated residential areas, important government agencies, airports, subways, stations, ports, petrochemicals, metallurgical mining, power plants, and places that require fire and explosion prevention.
