Introduction

DHDL is pleased to announce the successful delivery and operation of a large-scale power distribution project in Ethiopia.

For this project, DHDL supplied 20 units of 3.15MVA oil-immersed power transformers, with a total project capacity of 63MVA. The transformers are used for local industrial facilities and regional power distribution system construction, helping improve power supply stability and infrastructure reliability.

The project required strong manufacturing coordination, stable batch delivery, reliable outdoor performance, and technical support for overseas installation. With mature production management, strict factory testing, professional export packaging, and on-site technical assistance, DHDL successfully completed the project and supported the customer’s power infrastructure development.

1. Project Overview

This Ethiopia power distribution project is one of DHDL’s important overseas transformer delivery cases in the African market.

The project included:

Project Country: Ethiopia
Product Type: Oil-Immersed Power Transformer
Capacity: 3.15MVA per unit
Total Project Capacity: 63MVA
Quantity: 20 Units
Voltage Level: 33kV
Standard: IEC Standard
Application: Industrial Park and Regional Power Distribution System
Installation Environment: High-temperature, dusty, outdoor environment
Delivery Time: 50 Days

The transformers were designed for long-term outdoor operation and stable power distribution performance under challenging local environmental conditions.

2. Why This Project Matters

Reliable power distribution equipment is essential for industrial development, infrastructure construction, and regional electricity supply.

In many overseas markets, especially in areas with high temperature, dust, long transportation routes, and outdoor installation conditions, transformers must be designed not only for rated capacity but also for real operating environments.

This project was not a single-unit delivery. It involved 20 transformers delivered as a complete batch. That means the customer required:

Consistent product performance
Stable electrical parameters
Reliable insulation and cooling design
Strict factory inspection
Efficient production scheduling
Professional export packaging
Smooth international transportation
Technical support for installation and operation

For DHDL, the project demonstrated its ability to manage large-volume transformer orders for overseas power infrastructure projects.

3. Project Challenges

Large-Scale Batch Delivery

The project required 20 units of 3.15MVA transformers. Batch delivery places higher requirements on factory capacity, production planning, raw material coordination, and quality consistency.

Each unit needed to meet the same technical standard and performance expectations. For power distribution projects, consistency is especially important because unstable product quality may increase future maintenance risks.

Harsh Outdoor Operating Environment

The project site in Ethiopia required transformers to operate in a high-temperature and dusty outdoor environment.

This created higher requirements for:

Heat dissipation
Anti-corrosion performance
Sealing structure
Insulation reliability
Long-term mechanical stability
Outdoor protection design

A standard design without environmental adaptation may increase the risk of overheating, insulation aging, dust-related issues, or reduced service life.

International Transportation Risk

The project involved long-distance international shipping and local transportation. Transformers are heavy electrical equipment, so transportation safety was a key concern.

During overseas delivery, transformers may face humidity, vibration, port handling, road transportation, and storage uncertainty. Proper packaging and loading protection are critical to reducing transportation damage.

Installation and Technical Coordination

For overseas power equipment projects, delivery is only one part of the work. The customer also needs support for installation, technical confirmation, and smooth commissioning.

DHDL provided technical support to help the customer complete project implementation more efficiently.

4. DHDL’s Customized Solution

To meet the customer’s project requirements, DHDL provided a complete solution covering product design, manufacturing, testing, export packaging, delivery coordination, and technical support.

Batch Production Management

DHDL created a dedicated production plan for the 20-unit transformer order. The production team coordinated materials, production schedules, assembly processes, and inspection steps to ensure timely delivery.

This helped the customer reduce project delays and keep the power distribution construction schedule moving forward.

Reinforced Structure for Outdoor Operation

According to the local high-temperature and dusty conditions, DHDL optimized the transformer design for better long-term operation.

The solution focused on:

Improved heat dissipation design
Reliable insulation structure
Anti-corrosion treatment
Stable sealing performance
Outdoor operation adaptability

These design considerations help improve transformer reliability in demanding environments.

IEC Standard Compliance

The transformers were manufactured according to IEC standard requirements. This was important for project acceptance, safe operation, and technical compatibility with the customer’s power distribution system.

For overseas customers, standard compliance helps reduce project risk and makes later operation, maintenance, and technical documentation more reliable.

5. Manufacturing and Quality Control

For transformer projects, manufacturing quality is one of the most important factors affecting long-term operation.

DHDL focuses on process control, not only final inspection. From raw material inspection to core assembly, coil winding, insulation treatment, vacuum drying, final assembly, and factory testing, each step affects the transformer’s performance.

For this Ethiopia project, DHDL paid special attention to:

Core and coil manufacturing stability
Insulation treatment
Cooling performance
Electrical parameter consistency
Mechanical structure reliability
Factory testing before shipment

Before delivery, the transformers went through strict inspection to confirm that they met the project requirements and were ready for overseas operation.

6. Export Packaging and Transportation Support

Because the project involved international transportation, packaging was a key part of the delivery plan.

DHDL adopted professional export protection to reduce transportation risks during sea freight and local delivery.

The packaging solution focused on:

Moisture protection
Anti-vibration reinforcement
Stable equipment fixing
Transportation safety
Accessory protection
Container loading coordination

For large transformer orders, professional packaging is not a small detail. It directly affects whether the equipment can arrive safely and be installed without unnecessary delays.

7. On-Site Technical Support and Project Operation

After delivery, DHDL provided technical guidance and support for project installation and operation.

The technical support helped the customer:

Confirm installation requirements
Understand transformer operation points
Complete commissioning more efficiently
Reduce installation uncertainty
Improve project execution speed

After the project was put into operation, the equipment performed stably and met the customer’s local power distribution needs.

This successful operation further proved DHDL’s ability to support overseas power projects from production to delivery and technical service.

8. What This Project Means for DHDL’s Global Market
