Product Description
Product Description

* This High Voltage Power Transformer is produced in accordance with Chinese national GB standards and the international IEC standards.
* It uses oil as the main insulation means of the transformer, and relies on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation, etc.
* The main components: iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure release valve), radiator, insulating casing, tap switch, gas relay, thermometer, oil purifier, etc.
* Widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms and oil production platforms; especially suitable for use in flammable, explosive and other harsh environments.

 

Power Transformer Three Phase TOROIDAL S11 Wooden Case 11kv 20 Kv to 415v 2500 Kva Oil Type Electric 0

 

High Voltage Power Transformer Features:
The S11 series fully sealed oil-immersed power transformer developed and produced by the company has the advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effects and reduce pollution.
Compared with ordinary oil-immersed transformers, fully sealed transformers eliminate the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging so as to enhance operational reliability, and maintain normal operation without maintenance.


1.The transformer core is laminated with imported cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current. The core is bound to ensure the tightness of the core and reduce noise.
2.High and low voltage windings are made of oxygen-free copper, and low voltage windings of 500kVA and below adopt double-layer cylindrical structure. 630kVA and above adopt double helix or four helix structure, high voltage winding adopts multilayer cylindrical structure.
3.The transformer connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply.
4.The transformer is a fully sealed structure, which prolongs the service life, does not require hanging cores and maintenance.
5.The measured noise value is lower than the standard. After this series of transformers have been transported normally, the relevant parts can be installed without core inspection, and they can be put into operation once the acceptance test is qualified.
