Dry-type isolation transformer parameter table

Understanding Dry-Type Isolation Transformer Parameters

When selecting a dry-type isolation transformer,inverter custom the parameter table serves as your technical roadmap. Unlike traditional oil-filled transformers, these units use air or resin for cooling, making them ideal for sensitive environments like hospitals or laboratories where safety is paramount.

Key Parameters to Consider

Every reliable manufacturer, including China Hongye Electric, provides detailed specifications covering these essential aspects:

• Input/Output Voltage: Standard ranges from 110V to 480V, with custom voltages available
• Frequency: Typically 50Hz or 60Hz, selectable per application
• kVA Rating: Capacity from 0.5kVA to 2500kVA for different load requirements
• Insulation Class: Usually Class F (155°C) or Class H (180°C)
• Winding Material: 100% copper or aluminum options

How to Read Manufacturer's Parameter Tables

Most dry-type isolation transformer datasheets follow industry-standard formatting. China Hongye Electric's documentation, for instance, clearly separates electrical characteristics from physical dimensions and environmental ratings.

What's Often Overlooked in Parameter Sheets?

While most buyers focus on voltage and capacity, these critical specs deserve equal attention:

• Temperature Rise: Typically 80K, 100K, or 115K ratings
• Sound Level: Measured in dB at 1m distance
• Overload Capacity: Short-term handling capability
• Cooling Method: AN (air natural) or AF (air forced)

As a transformer manufacturer with 20 years' experience, we at China Hongye Electric recommend verifying all claimed parameters through third-party test reports when available.

Customization Options Beyond Standard Parameters

Standard dry-type isolation transformers might not fit specialized applications. That's where China Hongye Electric's non-standard customization capabilities become valuable:

• Special voltage ratios (e.g., 415V to 380V)
• Uncommon frequency requirements
• Enhanced protection (IP54 or higher)
• Custom terminal arrangements

Our engineering team at China Hongye Electric routinely handles such requests, having served over 10,000 industrial clients across diverse sectors.

FAQ: How Long Do Dry-Type Isolation Transformers Last?

With proper installation and maintenance, quality units typically operate for 20+ years. Key factors affecting lifespan include:

• Operating temperature (stay within rated limits)
• Load profile (avoid continuous overload)
• Environmental conditions (humidity, dust, etc.)

All our transformers undergo full factory testing including load, temperature rise, and insulation resistance checks before shipment.
