1. Industrial Park Development in Southeast Asia Driving Transformer Demand Growth

In recent years, global manufacturing supply chains have continued to shift. Southeast Asia has attracted significant investment from manufacturing companies due to its favorable industrial policies, labor resources, supply chain advantages, and strategic geographic location.

Countries including Vietnam, Thailand, Indonesia, and Malaysia are continuously expanding industrial parks, while industries such as automotive manufacturing, electronics production, renewable energy, and precision machinery processing are developing rapidly. These industries have created higher requirements for stable, efficient, and safe power supply systems.

According to market research forecasts, the Southeast Asian electricity transmission and distribution market is expected to grow from USD 57.39 billion in 2025 to USD 95.75 billion by 2031. This indicates that demand for industrial power distribution equipment in the region is expected to enter a period of rapid growth over the coming years.

2. Higher Transformer Requirements from Southeast Asian Industrial Parks

Industrial parks are significantly different from ordinary commercial power applications. They typically feature:

• High electricity consumption capacity
• Long operating hours
• Significant load variations
• Continuous production requirements

Industries such as automotive manufacturing, electronics factories, and new energy battery production rely heavily on automated equipment that requires continuous and stable operation. Therefore, power quality and equipment reliability are critical factors.

At the same time, Southeast Asia is characterized by a tropical climate environment, with long-term operating conditions including:

High Temperature

High annual average temperatures reduce equipment cooling efficiency and increase transformer temperature rise.

High Humidity

High humidity accelerates insulation material aging and may reduce electrical performance over time.

Heavy Rainfall

Outdoor equipment must withstand moisture, water ingress, and weather exposure challenges.

Coastal Salt Spray Corrosion

Salt-laden air increases the risk of corrosion on metal components and reduces equipment service life.

These environmental factors directly affect transformer insulation performance, cooling capability, corrosion resistance, and operational lifespan.

For the Southeast Asian market, transformer design must fully consider local environmental characteristics. Through structural optimization, enhanced insulation protection, improved heat dissipation, and strengthened anti-corrosion measures, transformers can achieve long-term stable operation even under complex tropical conditions.

3. Transformer Solutions for Industrial Parks

3.1 Oil-Immersed Power Transformers

With advantages such as a wide capacity range, stable operation, and excellent heat dissipation performance, oil-immersed transformers are among the most widely used power equipment in the main distribution systems of industrial parks.

Oil-immersed power transformers are suitable for applications including industrial park substations, large manufacturing plants, renewable energy industrial bases, and infrastructure projects.

Main Technical Specifications:

The products use high-quality core materials, high-performance insulation systems, and proven manufacturing processes. While ensuring reliable long-term operation, they effectively reduce operating losses and improve overall energy efficiency.

Zisheng Electric’s oil-immersed transformers are designed to meet the demanding requirements of industrial power systems, providing reliable power conversion and distribution solutions for large-scale industrial applications.

[Southeast Asia-Specific Design]

Designed specifically for tropical and rainy climates, this series of transformers comes standard with a C4-H high corrosion protection coating system, effectively resisting coastal salt spray corrosion.

The transformer structure has been optimized with improved oil conservator sealing design and radiator layout, ensuring reliable full-load operation even under an annual average temperature of 35°C. This prevents transformer oil from moisture absorption, oxidation, and performance degradation caused by high-temperature operating conditions.

3.2 Dry-Type Transformers

With the rapid development of industries such as electronics manufacturing, semiconductor production, and automated factories, dry-type transformers are becoming increasingly popular in Southeast Asian industrial facilities due to their advantages in safety, environmental protection, and easy maintenance.

Dry-type transformers feature:

• Oil-free operation
• Excellent fire resistance
• Flexible installation options
• Low maintenance costs
• Stable and reliable operation

They are particularly suitable for applications where fire safety, environmental requirements, and indoor installation conditions are important.

Main Technical Specifications:

Applications Include:

• Electronics manufacturing factories
• Semiconductor production workshops
• Data centers
• Precision industrial facilities

[Safety and Cleanliness Upgrade]

Designed specifically for the strict cleanliness requirements of electronics factories and semiconductor manufacturing environments, this series of dry-type transformers adopts an H-class (180°C) heat-resistant insulation system and enhanced vacuum epoxy resin casting technology.

The improved design not only provides excellent moisture and dust resistance but also maintains outstanding insulation performance in environments with relative humidity ≥90%, significantly reducing the risk of short circuits caused by condensation.

3.3 Package Substation Solutions

To meet the rapid construction requirements of industrial parks, modular package substation solutions offer advantages including:

• Factory prefabrication
• Short installation periods
• Small footprint
• Convenient transportation
• Flexible expansion capability

These solutions are widely applicable to:

• New industrial park development
• Solar and renewable energy projects
• Temporary power supply projects
• Long-term permanent power distribution systems

4. Southeast Asia Industrial Park Project Cases

Vietnam Industrial Park 22kV Distribution Transformer Project

A large electronics contract manufacturing factory in Vietnam launched a second-phase expansion project. The existing power supply system experienced frequent trips during the rainy season, causing the automated production line to stop for more than 4 hours per month, resulting in direct production losses of nearly USD 80,000.

The customer urgently required replacement of the 22kV main distribution transformer and requested completion of delivery and installation within 45 days.

Key Challenges:

• Must comply with Vietnam Electricity (EVN) requirements, including Dyn11 vector group configuration and grid connection protection standards
• Limited factory space required a compact transformer design suitable for indoor installation and fire safety requirements
• Extremely short delivery schedule, while conventional suppliers typically required around 90 days

Zisheng Solution:

Zisheng Electric dispatched a technical team for on-site assessment and provided two units of SCB13-2500/22 dry-type transformers with customized solutions.

Key improvements included:

• Adoption of amorphous alloy core materials to reduce no-load losses
• Upgrade of insulation protection level from standard IP20 to IP32 to address condensation issues during the rainy season
• Optimization of transformer structure for compact indoor installation

Delivery and Results:

Equipment installation and grid connection commissioning were completed on the 38th day, one week earlier than the customer’s expected schedule.

The system has operated for more than 400 days without failure. In the customer’s appreciation letter, they specifically mentioned:

“Voltage fluctuation has remained within ±3%, and production interruptions caused by power issues have been reduced to zero.”

The customer has now signed a follow-up supply agreement with Zisheng Electric for the third-phase expansion project.
