Key Advantages

Reduced Line Losses and Improved Power Supply Efficiency

Installed close to the load, these transformers shorten the low-voltage supply radius, significantly reducing the length of low-voltage lines. Low-voltage line losses are reduced by over 99%, greatly enhancing energy utilization efficiency.

Efficient and Energy-Saving Structural Design

Features a high-efficiency, energy-saving wound core design, improving electrical performance and energy efficiency. Compact and lightweight, making installation and transportation easier and more adaptable to various environments.

Flexible Installation

Utilizes a pole-mounted suspension installation, allowing direct mounting on utility poles without occupying ground space -- ideal for rural and suburban areas.

Cost-Effective

Requires low capital investment compared to traditional transformer systems, making it well-suited for large-scale deployment.

High Reliability and Easy Maintenance

Built with a fully enclosed structure, offering excellent protection against dust and moisture. Strong overload capacity ensures stable operation during temporary load surges. Highly reliable for continuous operation and easy to maintain, reducing operational and maintenance costs.

5kVA Model Features

Compact design: Small size, suitable for installation in various places.
Flexible application: Suitable for small shops, household equipment and other scenarios.
High cost performance: The perfect combination of high-quality performance and reasonable price.

This 5kVA single-phase pole transformer is designed for users with limited space. Despite its small size, it has powerful performance and can meet daily electricity needs. It is an ideal choice for both home and small commercial places.
