⚙️ Product Description
Single-Phase Oil-Immersed Power Transformer

Types of Single-Phase Pole-Mounted Transformers

Our product range includes standard models and advanced Completely Self-Protected (CSP) transformers, engineered for maximum efficiency and reliability in overhead power distribution systems.

Key Features of CSP Transformers:

  • Built-in surge arrester: High-voltage side protection against lightning and overvoltage.
  • Integrated circuit breaker: Low-voltage side protection to prevent overloads and short circuits.
  • Internal protective fuse: Enhanced safety and system isolation.

The all-in-one CSP design significantly reduces the need for external protection devices, simplifying installation and lowering maintenance costs.

❓ Frequently Asked Questions
What is a Completely Self-Protected (CSP) transformer?
A CSP transformer integrates internal protection components including a surge arrester, a low-voltage circuit breaker, and a protective fuse. This design eliminates the need for many external protective devices.
What are the primary applications for pole-mounted transformers?
They are primarily used in overhead power distribution systems to step down high voltage to residential or commercial usable levels (e.g., 120V/240V).
What winding materials are available?
Depending on the customer's requirements for efficiency and cost, both copper and aluminum winding materials are available.
How are the transformers protected against environmental factors?
These units are oil-immersed for effective cooling and insulation, and the tanks are sealed to withstand outdoor weather conditions in overhead installations.
What is the standard warranty period for these transformers?
The standard warranty is 2 years, ensuring long-term reliability and performance for power distribution networks.
Are custom voltage ratings available?
Yes, while standard high voltages include 13800V and 33000V, custom input and output voltage configurations can be manufactured upon request.
