100 kVA Oil-Immersed Distribution Transformer

100 kVA Oil-Immersed Distribution Transformer is specified for 100 kVA oil-immersed distribution service. It uses ONAN (Oil Natural Air Natural) cooling. Engineering details address designed for Distribution Efficiency, construction, application context, and electrical data for project selection.

Designed for Distribution Efficiency

For this 100 kVA rating, designed for distribution efficiency affects how the transformer is selected, protected, and operated in the field.

• In the realm of last-mile power distribution, stability and footprint matters.
• The 100 kVA Oil Immersed Transformer is engineered specifically for compact installation environments, such as pole-mounted setups in rural electrification projects or pad-mounted units for small urban clusters.
• Instead of relying on bulky cooling radiators, this rating utilizes a high-performance corrugated tank design.
• This structure not only maximizes heat dissipation surface area but also allows for the thermal expansion of oil, keeping the 100kva transformer strictly hermetically sealed against moisture and dust ingress.

Core Engineering & Material Quality

The core engineering and material quality details below highlight design choices that matter during continuous distribution service.

• We move beyond generic manufacturing by implementing a precision-cut silicon steel core.
• The core laminations are stacked using a step-lap method to drastically reduce the no-load current.
• Magnetic Circuit: Optimized using high-permeability grain-oriented silicon steel to minimize hysteresis loss.
• Coil Construction: The HV and LV windings are wound with oxygen-free copper (or aluminum upon request) to ensure high electrical conductivity.
• This robust winding structure enhances the transformer 100kva capability to withstand sudden short-circuit mechanical forces.

Ideal Application Scenarios

Application guidance links the transformer rating with the substations, industrial loads, and site conditions where it is normally used.

• Due to its balance of cost and performance, this 100 kva transformer 3 phase model is the go-to choice for: Rural Grid Upgrades: Extending power lines to remote villages.
• Agricultural Zones: Powering irrigation pumps and small agro-processing machinery.
• Residential Complexes: Serving small communities or villa clusters with stable 400V output.
