Product Oview

The 150 kVA pole mounted transformer is a single phase pole transformer designed for overhead power distribution networks.It is widely used in rural electrification projects, urban secondary distribution lines, and utility grid extensions.

As a professional transformer manufacturer with extensive export experience, we supply 150 kVA pole mounted transformers that comply with IEC, IEEE, and ANSI standards, ensuring stable performance, high efficiency, and long service life under various climatic conditions.

How Much Power Can a 150 kVA Pole Mounted Transformer Supply?

A 150 kVA pole-mounted single-phase transformer has a rated apparent power of 150 kVA. The actual active power it can supply depends on the power factor (cosφ) of the load, calculated using the core formula:P=S×cosφWhere:

P = Available active power (Unit: kW)

S = Rated apparent power of the transformer (150 kVA)

cosφ = Power factor of the load

Available Power Under Different Load Scenarios

Residential Loads (cosφ ≈ 0.8~0.9)

When cosφ = 0.8, P=150×0.8=120 kW

When cosφ = 0.9, P=150×0.9=135 kW

Such loads mainly consist of lighting and household appliances. A 150 kVA transformer can meet the daily electricity demand of approximately 200–250 ordinary households.

Small Commercial/Industrial Loads (cosφ ≈ 0.7~0.8)

When cosφ = 0.7, P=150×0.7=105 kWThese loads include small motors and commercial equipment, capable of supporting the power supply for 1–2 small processing plants or one medium-sized commercial network.

Pure Resistive Loads (cosφ = 1, e.g., electric water heaters, electric furnaces)

P=150×1=150 kWIn this case, the active power output by the transformer is equal to the rated apparent power, reaching the maximum power supply capacity.
