In power systems, transformer capacity selection needs to match load requirements. 150 kVA Three Phase Distribution Transformer is commonly found in small and medium-sized industrial enterprises, commercial complexes or regional power supply nodes. It has obvious advantages in installation space, initial investment and daily maintenance, and is more suitable for projects with requirements for cost control and operation and maintenance convenience.
CHBEB once supplied 10 units of 150 kVA Three Phase Distribution Transformer to the power system in Uzbekistan. They chose this model from the design perspective. The 150 kVA capacity is often used in small and medium-sized industrial and commercial power supply, residential community distribution, or small distributed photovoltaic grid connection scenarios. Compared with smaller-capacity transformers, such as 50 kVA models, the 150 kVA Three Phase Distribution Transformer can support a larger total load power and adapt to working conditions with large instantaneous current such as motor starting, but its size, weight and raw material usage also increase accordingly. Compared with larger-capacity transformers, such as 500 kVA Distribution Transformer, the 150 kVA model usually has a relatively simplified structure. Its heat dissipation design may rely more on natural convection rather than forced air cooling, and installation and maintenance are often more convenient, but its tolerance margin for extreme overload or impact current is relatively limited.
150 kVA Three Phase Distribution Transformer is the most widely used type, suitable for high-voltage and large-capacity power transmission and distribution systems, including power plant step-up, grid transmission, substation step-down and factory distribution.
With the promotion of new energy projects such as wind power and photovoltaic, UHV projects, smart grids, and urban and rural power grid renovation, the demand for oil-immersed transformers has further expanded. At the same time, the improvement of energy efficiency standards and environmental protection requirements has also promoted the upgrading of traditional oil-immersed transformers toward low-loss and environmentally friendly types, and has created market demand for energy-saving and environmentally friendly oil-immersed transformers.
The 150 kVA Three Phase Distribution Transformer produced by CHBEB fully responds to this trend. It optimizes the core structure and winding design, reduces no-load loss and load loss, and significantly improves the overall energy efficiency of the transformer. Compared with traditional models, our company’s products reduce energy efficiency loss by more than about 10% during operation.
At the same time, it uses transformer oil that meets environmental protection standards, with oxidation resistance, flame retardancy, non-toxic and harmless characteristics, meeting modern environmental protection requirements. The oil tank adopts a sealed structure and is equipped with an explosion-proof device to eliminate environmental pollution and safety hazards.
High-Quality Copper Core Winding
Excellent electrical conductivity, low thermal expansion coefficient, high mechanical strength, strong short-circuit resistance, reducing heating caused by load fluctuations.
Advanced Core Material
Uses high-permeability silicon steel sheets, with strict interlayer insulation treatment to reduce eddy current loss.
Fully Sealed Oil Tank Design
Can effectively prevent environmental moisture and air from entering, reduce oil deterioration, and keep insulation performance stable.
Intelligent Temperature Control Protection (Optional)
Monitors oil temperature and winding temperature in real time, prevents overheating, and extends equipment life.
