FAQ
1. How to Calculate Required Transformer Capacity
Formula: kVA = Load Power (kW) ÷ Power Factor (typically 0.8)
Example: 50kW equipment → 50 ÷ 0.8 = 62.5kVA (select 63kVA model)
2. Why is electrical isolation important?
Electrical isolation prevents a direct electrical path between source and load circuits, protecting personnel and equipment from electrical shock and transient disturbances. It minimizes the effects of ground loops, harmonics, and high-frequency noise that can interfere with sensitive equipment. In automation and control systems, isolation enhances signal integrity and system reliability. Rex Power Magnetics designs its transformers with high dielectric insulation and low interwinding capacitance to maximize electrical separation while maintaining energy efficiency and quiet performance.
3. Are custom dry type industrial isolation transformers available?
Yes. GE Transformer offers fully customized general purpose isolation transformers tailored to customer requirements. Options include non-standard voltage ratios, kVA ratings, special impedance levels, and custom enclosures. Our engineering team can design transformers with enhanced shielding, harmonic mitigation, or specific thermal performance targets. Each custom-built unit is produced and tested to the same rigorous standards, ensuring full compliance with applicable codes and reliable integration into specialized systems.
4. What is your minimum order quantity (MOQ)?
We support flexible MOQs. For most export orders, MOQ starts from 1 unit, especially for project-based procurement.
5. What is the typical delivery time?
Standard models typically require 15-20 days, depending on capacity, quantity, and customization requirements.
6. What maintenance is recommended for dry type industrial isolation transformers?
These transformers are low-maintenance devices. Periodic inspections should include verifying terminal tightness, ensuring unobstructed ventilation, and checking for dirt, corrosion, or insulation discoloration. The polyester resin coating minimizes moisture absorption and mechanical movement, reducing long-term maintenance needs. In dusty or high-humidity environments, more frequent cleaning and visual checks are advisable. With routine inspections and proper loading, GE Transformer isolation transformers provide decades of dependable service.
7. Do you offer customization and OEM services?
Yes, we provide full customization and OEM/ODM services based on your project requirements.
8. What information is required for a quotation?
