As a specialized manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. offers robust and reliable solutions for industrial power management. Our 100kva Dry-Type Industrial Isolation Transformer for 440V to 220V Three-Phase Conversion SG-Type is engineered to provide safe, efficient, and stable voltage transformation for demanding industrial environments. Designed with a focus on durability and performance, this transformer ensures your critical operations are powered consistently, protecting sensitive equipment from voltage fluctuations and electrical noise.
This transformer delivers core value by providing a physical barrier between your primary power source and your equipment, enhancing safety and system integrity. It is an essential component for facilities requiring a specific voltage level different from the incoming supply, enabling the seamless operation of machinery, control systems, and other three-phase loads.
Key Features and Technical Specifications:
- Dry-Type Design: Utilizes air as the cooling medium, eliminating the risks and maintenance associated with liquid coolants. This makes it safer, environmentally friendly, and suitable for installation in areas where fire safety is a priority.
- Isolation Function: Provides galvanic isolation between the primary (440V) and secondary (220V) circuits. This protects downstream equipment from surges, transients, and noise on the primary side, and prevents ground loop issues.
- SG-Type Construction: Indicates a specific, robust construction style designed for industrial stability and longevity, often featuring enhanced mechanical strength and thermal management.
- High Efficiency: Designed with high-quality core and winding materials to minimize energy losses, contributing to operational cost savings over its lifespan.
- Low Noise Operation: Engineered to operate with minimal audible noise, making it suitable for installations near workspaces.
- Flexible Installation: The dry-type design allows for installation in various indoor locations without special containment requirements.

Frequently Asked Questions (FAQ):
-
What is the primary advantage of a dry-type transformer over an oil-filled one?
Dry-type transformers use air as insulation and cooling, eliminating risks of oil leakage, fire, and environmental contamination. They are safer, require less maintenance, and are suitable for indoor installations without special fire protection measures. -
Can this transformer handle different input frequencies, like both 50Hz and 60Hz?
Yes, the standard design typically accommodates both 50Hz and 60Hz operation. The core and winding design are optimized for this frequency range, ensuring proper performance. -
Is the 440V to 220V conversion ratio fixed, or can other voltage ratios be provided?
The described model is specifically designed for 440V input to 220V output. However, as a manufacturer, we can customize transformers for different voltage conversion ratios upon request to match your specific supply and load requirements. -
What does "SG-Type" construction mean for this transformer?
"SG-Type" refers to a specific, robust construction style commonly used for industrial dry-type transformers. It often denotes features like reinforced mechanical structure, improved thermal dissipation, and design elements suited for stable, long-term industrial service. -
What are the typical installation requirements for this 100kva unit?
It is designed for floor mounting in a clean, dry, and well-ventilated indoor environment. Adequate space around the unit for air circulation and access for maintenance should be provided. Specific mounting details and clearance requirements are provided in the installation manual. -
Does the transformer come with any protective devices or monitoring features?
Basic units include essential terminals and connections. Optional features like temperature sensors, protective enclosures (higher IP ratings), or terminal boxes can be incorporated based on your order specifications. -
What is the expected service life of this dry-type isolation transformer?
With proper installation and operation within its specified ratings, a well-maintained dry-type transformer can have a service life of 20 years or more. The quality of materials and construction significantly influences longevity. -
Can we get custom winding materials, like preferring copper over aluminum?
Yes. The winding material (copper or aluminum) is often customizable. Copper windings generally offer better conductivity and lower losses, while aluminum can be a cost-effective alternative. This choice can be discussed during the ordering process.
