Product Introduction
Transformer Showcase
Transformer Detail 1 Transformer Detail 2

1. High Efficiency and Low Loss

Utilizing high-quality silicon steel sheets (such as oriented silicon steel) and advanced winding technologies (such as foil winding or helical winding) to reduce no-load losses (iron loss) and load losses (copper loss).

2. Energy-saving Design

Complies with international energy efficiency standards. The efficiency of some models can reach over 99%, significantly reducing long-term operating costs.

Core Technology
Customization

3. Adaptability to Complex Power Grids

Equipped with wide voltage regulation (OLTC or no-excitation) and harmonic suppression (Dyn11 connection group) to ensure compatibility with new energy grids like photovoltaic and wind power.

4. Customization and Global Applicability

Flexible design capacities from 10kVA to 1000MVA, with voltage levels up to ±1100kV. Special protection options like salt spray prevention and explosion-proof designs are available.

Frequently Asked Questions
What is the typical lifespan of a transformer?
A well-maintained power or substation transformer can typically last between 30 to 50 years.
What are the benefits of using compact transformers?
Benefits include reduced space requirements, lower energy consumption, less noise, and improved efficiency. They are ideal for urban or industrial settings where space is limited.
How efficient are these power transformers?
Our transformers are highly efficient, typically ranging from 90% to over 99%, depending on the specific design and load conditions.
What is the difference between a step-up and step-down transformer?
A step-up transformer increases voltage while decreasing current for transmission, whereas a step-down transformer decreases voltage for safe local distribution.
Can dry-type transformers be used outdoors?
Yes, certain dry-type transformers specifically designed with weatherproof enclosures are rated for outdoor environments.
What materials are used in the transformer core?
The core is typically made of high-grade silicon steel, which is designed to significantly reduce energy loss due to magnetic hysteresis.
