160 kVA Oil-Immersed Distribution Transformer

160 kVA Oil-Immersed Distribution Transformer is specified for 160 kVA (IEC Standard) oil-immersed distribution service. It steps Up to 33 kV networks to 400V / 230V loads. It uses ONAN (Oil Natural Air Natural) cooling. Engineering details address operational Versatility and Capacity Coverage, construction, application context, and electrical data for project selection.

Operational Versatility & Capacity Coverage

For this 160 kVA rating, operational versatility and capacity coverage affects how the transformer is selected, protected, and operated in the field.

• As a staple in the distribution network, the 160 kVA Oil Immersed Transformer serves as a robust power solution for light industrial zones and commercial infrastructure.
• It is specifically engineered to handle loads that slightly exceed the capacity of smaller 100 kVA units but do not require the bulk of a 200 kVA system.
• It is worth noting that this rating is the modern IEC standard replacement for older specifications.
• If your project requirements or replacement parts list calls for a legacy 150 kva transformer, the 160 kVA model is the perfect upgrade.
• It offers a higher safety margin and overload capability within a similar physical footprint, effectively covering the 150 kVA demand with superior efficiency.

Dielectric System & Cooling Dynamics

The dielectric system and cooling dynamics details below highlight design choices that matter during continuous distribution service.

• True to its classification as a high-performance liquid filled transformer, this rating relies on premium mineral oil as both an insulation medium and a cooling agent.
• Unlike dry-type counterparts, the liquid dielectric provides self-healing properties for minor partial discharges and ensures uniform heat transfer from the core to the tank walls.
• We strictly utilize PCB-free mineral oil that undergoes vacuum dehydration before filling.
• This process removes moisture content to parts-per-million (ppm) levels, ensuring the dielectric strength remains high throughout the transformer's lifecycle.
• The tank design accommodates the volumetric expansion of the liquid during peak loads, maintaining internal pressure balance.

Construction Highlights

These construction highlights points connect the electrical rating with grid conditions, downstream equipment, and maintenance expectations.

• Tank Durability: The casing is fabricated from cold-rolled steel plates with reinforced seams to prevent leakage-a critical factor for any liquid filled transformer.
• The surface is treated with a multi-layer coating system (phosphating + powder coating) to resist corrosion in humid or coastal environments.
• Coil Integrity: The windings use high-elongation copper (or aluminum) wire, wound with variable tension control.
• This ensures the coil remains tight and resistant to axial forces during fault conditions.

Recommended Applications

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

• This 160 kVA unit is positioned for scenarios requiring steady baseload power with occasional peaks: 1.
• Small Manufacturing Workshops: Powering lathes, CNC machines, and conveyors.
• Commercial Buildings: Support for HVAC systems and elevators in mid-sized office blocks.
• Replacement Projects: Directly swapping out older 150 kva transformer units in aging grids to improve reliability.
