Product Description

Basic Info.

Product Introduction

Kete oil-immersed 3D wound core transformer is an energy-efficient power transformer, featuring a 3D wound core structure and using oil as the cooling and insulating medium.

 

Product Advantages

1.High Efficiency & Energy Saving: 3-phase wound core ensures even magnetic circuit, cutting traditional laminated core joint loss. No-load/load loss is significantly reduced, with energy efficiency up to S20 standard and above.

 

2.Low-Noise Operation: Fewer wound core joints and lower magnetic resistance minimize operational vibration/noise, ideal for noise-sensitive areas (residentials, hospitals, schools).

 

3.Superior Heat Dissipation: Mineral oil as cooling medium effectively lowers operating temperature, supporting long-term high-load use and extending equipment life.

 

4.Strong Short-Circuit Resistance: Stable wound core structure, rational winding design, and mostly circular core cross-section (good fastening) enable it to withstand large short-circuit current impacts.

 

5.Compact Structure: 3D wound core design reduces size/weight, easing transportation/installation and saving space—perfect for limited-space scenarios.

 

Operating Conditions

Ambient Temperature: Maximum: +40℃; Minimum: -25℃ (Wider temperature ranges available)

 

Relative Humidity: ≤90% (Higher protection levels available)

 

Altitude: ≤1000m (Special designs for higher altitudes available)

 

Scope of Application

It is widely applied in core fields including: power transmission and distribution within power systems, new energy power generation (e.g., wind power, PV), self-owned power supply for industrial enterprises, and various infrastructure construction projects (e.g., transportation, construction-related supporting power needs).

FAQ

1.Will Kete provide guidance documents for installation?

 

For large transformers that require the removal of some accessories to fit into containers, we will provide an installation video and an electronic version of the installation instructions.

 

2.What is the manufacturing and delivery lead time for Kete oil-immersed transformers?

Generally speaking, if the customer provides detailed design drawings and specification requirements, transformers below 2500KVA can be completed within approximately 20 days; transformers above 2500KVA usually take about 30 to 40 days. The specific lead time depends on the complexity of the transformer.

 

3.What is the packaging for Kete oil-immersed transformers?
For bulk cargo, we will use wooden cases for packaging; for full containers, we will use wooden pallets to reinforce the packaging.
