S-M-1600kVA Oil-immers Transformer

3750 American Box Transformer

3600kVA/34.5 kV Dry-Type Transformer

Designed for indoor use up to 3600m altitude | 34.5kV / 4.16kV

Key points:

1.Impedance 8.34% | Low total loss

2.Dyn11 vector group | Handles unbalanced loads

3.HV power frequency withstand 95kV | High safety margin

4.Complies with GB & IEC standards

400KVA 15KV Oil Transformer

Product model: S-M-400/15-0.4

Basic parameters: Three box fully sealed 400KVA capacity Voltage ratio: 15-0.4 Frequency: 50Hz Impedance 4.03

Core selling point: ODM discharge angle: For 400KVA/15KV transformers, 270 ° (negative half cycle peak) is the most dangerous discharge angle to be cautious of,Usually indicates the presence of air gaps or moisture inside the oil/paper insulation, and immediate oil chromatography analysis and drying treatment are required

Designed for Your Single-Phase Pole-Mounted Distribution Projects

Used across residential service areas, rural electrification projects, overhead distribution networks and small commercial power systems — each transformer designed for the specific load, voltage class and environmental conditions of your application.

How to Select the Right Transformerfor Your Project

Choosing the right oil-immersed transformer comes downto six confirmations. Walk through the steps below -orsend what you already have, and our engineers will fill inthe rest.

Confirm Load Capacity

State the rated kva and any overload or duty-cycle requirements your transformer must support. Include both continuous and short-term loading conditions so we design the correct winding and cooling system.

Overload capability (if required)
Rated kva / continuous load rating
Load cycle or duty-cycle specifications

Confirm Voltage Ratio

Define the primary and secondary voltage levels, including taps and regulation range. Specify if taps are off-load or on-load to ensure the correct tap changer is selected.

Primary / secondary rated voltages
Tap range and step settings
Tap changer type (nlttc / oltc)

Confirm Frequencv & Phase

Specify the system frequency and phase configuration your transformer must operate on. This affects core design, losses, and winding configuration.
- Rated frequency (50hz / 60hz)
- Phase configuration (single-phase / three-phase)
- System neutral grounding requirements

Confirm Installation

Detail the installation environment and site conditions to ensure proper design and protection. This includes location, mounting, and environmental factors that impact the unit’s design.

Mounting type (pole / pad / substation)
Altitude, ambient temperature, and humidity
Enclosure and environmental ratings (ip code / nema)

Confirm Standards & Testing

State which standard your project is bid against, and what testing documentation you’ll need. Many tenders require third-party witnessed tests — flag this early so we plan it into the build schedule.

Iec 60076 / ansi / gb / project spec
Routine + type test reports
Fat or third-party witnessed inspection

Accessories & Protection

List all required accessories and protective devices for the transformer. This ensures we include all necessary components for operation, monitoring, and safety compliance.

Bushings, lightning arresters, and connectors
Monitoring devices (temperature, pressure, oil level)
Protective relays and control components
