Our company provides a wide range of single-phase pole-mounted transformers, also referred to as overhead transformers. The product lineup includes both standard models and advanced Completely Self-Protected (CSP) transformers, designed for maximum efficiency and reliability.
Key Features of the CSP Transformer:
• Built-in surge arrester: Located on the high-voltage side for lightning and overvoltage protection.
• Integrated circuit breaker: Located on the low-voltage side to prevent overloads and short circuits.
• Internal protective fuse: Provided for enhanced safety.
This all-in-one CSP design reduces the need for external protection devices, lowering installation costs and simplifying setup. This innovative solution ensures safer operation, easier maintenance, and cost-effective performance, making it an ideal choice for overhead power distribution systems.
