Corrosion Resistant 315KVA Single Phase Pole Mounted Transformer 13.2 kV / 220 V

The Single Phase Pole Mounted Cylindrical Transformer is a high-performance overhead distribution solution designed for temporary and permanent power supply applications such as construction sites, rural electrification, mining operations, and outdoor industrial facilities.

Engineered with corrosion-resistant materials, high thermal stability insulation systems, and reinforced cylindrical tank design, this transformer ensures reliable power conversion from medium voltage distribution lines (13.2kV) to low-voltage end-user systems (220V).

Its pole-mounted structure significantly reduces land occupation and installation cost, making it an ideal choice for fast-deployment and high-reliability power distribution networks in harsh environments.

• High Power Capacity Design (3150kVA)
  Supports large-scale temporary and industrial power demands with stable output performance.
• Corrosion-Resistant Outdoor Structure
  Special anti-corrosion coating and sealed tank design ensure long service life in coastal and humid environments.
• High Temperature & Anti-Explosion Performance
  Designed with advanced insulation oil system and thermal expansion safety control for hot climate regions.
• Compact Pole-Mounted Installation
  Eliminates the need for ground substations, reducing land cost and installation complexity.
• High Electrical Efficiency & Low Loss
  Optimized core design minimizes no-load and load losses, improving energy efficiency.
• Fast Deployment for Temporary Projects
  Ideal for construction sites, emergency power supply, and rapid infrastructure expansion.

In many tropical and high-temperature markets such as Southeast Asia, Middle East, Africa, and South America, pole-mounted transformers often face critical challenges including overheating, insulation aging, oil expansion risk, and corrosion damage.

• Frequent overheating under extreme ambient temperatures (>45°C)
• Insulation degradation caused by thermal stress
• Oil expansion leading to pressure imbalance and safety risks
• Coastal humidity causing rapid corrosion of tank and fittings
• High load fluctuation in construction and temporary power systems

• High-Temperature Resistant Insulation System
  Advanced Class F/H insulation materials ensure stable operation under continuous high thermal stress.
• Thermal Expansion Safety Design
  Equipped with optimized oil expansion buffer system to prevent internal pressure buildup.
• Anti-Explosion Structural Reinforcement
  Reinforced cylindrical tank design improves mechanical strength and fault pressure resistance.
• C5-M Marine Grade Anti-Corrosion Coating
  Multi-layer protective coating system for coastal and high-humidity environments.
• Improved Heat Dissipation Structure
  Enhanced radiator and airflow design ensures faster heat dissipation in tropical climates.
• Stable Operation Under Voltage Fluctuation
  Designed for unstable grid environments commonly found in temporary construction power systems.

Q1: Can this transformer operate in extremely high temperature environments?
Yes. It is specially designed with high thermal stability insulation and enhanced cooling performance for environments up to +55°C.

Q2: Is it suitable for temporary construction power supply projects?
Absolutely. It is widely used in construction sites, mining operations, and temporary infrastructure power systems.

Q3: How does it prevent corrosion in coastal areas?
The transformer uses C5-M grade anti-corrosion coating and sealed tank construction to resist salt spray and humidity.

Q4: Can it handle unstable load conditions?
Yes. It is designed for fluctuating loads with reinforced winding structure and improved voltage regulation performance.

Q5: What is the expected service life?
Under standard operating conditions, the service life is typically 25–30 years depending on maintenance and environment.

Q6: Can OEM customization be supported?
Yes. Voltage, capacity, insulation class, tank material, and protection level can all be customized.
