Key Features & Application Benefits

Flexible Medium-Voltage Configuration

Designed for distribution systems using either 2.4kV or 4.16kV primary voltage, this transformer offers greater flexibility for different utility networks. The 120/240V secondary configuration is suitable for supplying residential loads, small commercial facilities, and other low-voltage consumers.

Efficient Oil-Immersed Cooling

The transformer uses insulating oil as both an electrical insulation medium and a heat-transfer medium. During operation, heat generated by the core and windings is effectively transferred to the surrounding oil and dissipated through the tank, helping maintain dependable operating performance.

Reliable Outdoor Construction

A robust transformer tank and carefully designed internal components provide protection for the active part against common environmental influences. The construction is suitable for outdoor distribution applications where equipment may be exposed to changing weather and operating conditions.

Stable Voltage Transformation

The transformer is engineered to provide consistent voltage conversion from the medium-voltage supply to the 120/240V low-voltage system. High-quality magnetic core and winding components contribute to dependable electrical performance and efficient power delivery during normal operating conditions.

Suitable for Diverse Distribution Applications

With its compact capacity and flexible voltage configuration, the 50kVA distribution transformer can be applied to residential neighborhoods, rural power networks, light commercial buildings, and utility distribution projects. Its practical design makes it a suitable choice for applications requiring dependable low-voltage power from a medium-voltage network.

Generic Installation and Operation Instructions

The following guidelines provide a general reference for the installation and commissioning of distribution transformers. Actual installation work should always be carried out by qualified electrical personnel in accordance with the transformer manufacturer's technical documentation, applicable local regulations, and relevant electrical safety standards.

1. Preparing the Installation Site

Inspect and prepare the installation location before the transformer is delivered. Ensure that the foundation or supporting structure is properly constructed, level, stable, and capable of supporting the transformer and associated equipment. Adequate clearance, grounding facilities, and safe access for installation and maintenance should also be provided.

2. Installing the Supporting Structure

For pole-mounted applications, install the designated utility pole and supporting hardware in accordance with the approved engineering design. Verify the structural strength, vertical alignment, mounting position, and fastening points before lifting the transformer into position.

3. Installing and Assembling Transformer Components

Inspect the transformer and its accessories for any signs of damage before installation. Install the required bushings, mounting hardware, grounding connections, and other accessories according to the manufacturer's drawings and instructions. All mechanical connections should be properly secured before electrical connections are made.

4. Connecting the Primary and Secondary Wiring

Connect the high-voltage and low-voltage conductors according to the transformer nameplate, wiring diagram, and approved electrical design. Check phase identification, terminal connections, conductor clearances, grounding, and connection tightness carefully. All electrical connections must comply with applicable safety requirements and local electrical codes.

5. Pre-Commissioning Inspection and Testing

Before energizing the transformer, qualified personnel should perform the required visual, mechanical, and electrical inspections. Depending on the applicable specification, tests may include insulation resistance, winding resistance, voltage ratio, polarity or phase relationship, dielectric withstand, grounding continuity, and other routine checks.

After confirming that all test results are within the specified limits and that the installation is safe and complete, the transformer may be placed into service in accordance with the approved commissioning procedure.

Important: Installation, testing, and commissioning must be performed by qualified professionals. Always refer to the specific transformer manufacturer's drawings, technical specifications, and operating instructions before installation or energization.
