■ Product Overview & Description

Types of Single-Phase Pole-Mounted Transformers

We provide 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 long-term reliability in power distribution networks.

Key Features of the CSP Transformer System:

Built-in surge arrester: Located on the high-voltage side for superior lightning and overvoltage protection.
Integrated circuit breaker: Positioned on the low-voltage side to prevent damage from overloads and short circuits.
Internal protective fuse: Provides an additional layer of safety for the distribution system.

This all-in-one CSP design significantly reduces the need for external protection devices, lowering installation costs and simplifying field setup. It ensures safer operation, easier maintenance, and cost-effective performance for overhead power distribution systems.

Frequently Asked Questions

1. What is a CSP (Completely Self-Protected) transformer?

A CSP transformer includes internal protective components like a surge arrester, a low-voltage circuit breaker, and an internal fuse, eliminating the need for external protective equipment and simplifying installation.

2. What are the available cooling methods for these units?

These transformers primarily use the ONAN (Oil Natural Air Natural) cooling method, which is highly effective for oil-immersed distribution transformers.

3. What winding materials are used in construction?

Depending on client requirements and efficiency standards, we utilize high-quality Copper or Aluminum for the windings.

4. What is the standard warranty period for your transformers?

We provide a 2-year warranty on our pole-mounted transformers, ensuring long-term peace of mind and performance reliability.

5. Can the input and output voltages be customized?

Yes, we support a wide range of input voltages (e.g., 13.8kV, 33kV) and various output configurations (120V to 35kV) as per specific project designs.

6. What certifications do these transformers hold?

Our products are manufactured under strict quality controls and hold certifications including ISO9001-2000, ISO9001, and CCC.
