Quality Control: Our quality control system is comprehensive and multi-faceted. From the initial selection of high-grade raw materials sourced from reliable suppliers, we ensure that every component used in our products meets the highest quality standards.
Routine Tests:
Measurement of winding resistance
Measurement of voltage ratio
Check of vector group
Mesurement of impendance voltage and load loss
Measurement of no load oss and current
Separate-source voltage withstand test
Induced overvoltage withstand test
Dimension checking
Type Tests
Lighting impulse test
Temperature rise test
FAQs
Q: Why choose cast-resin over oil-filled for indoor sites?
A: Cast-resin units are oil-free and therefore eliminate oil-spill and fire-containment risks, making them safer and more acceptable for densely occupied or environmentally sensitive locations.
Q: How much extra capacity do fans provide?
A: Forced-air (AF) versions raise allowable continuous and short-term overload performance versus natural cooling; industry references show typical design uplifts in the 20–40% range depending on design and ambient conditions.
Q: Are these transformers suitable for outdoor installation?
A: Yes — with weatherproof enclosures and appropriate IP rating; however, envelope and ventilation design must follow the selected model’s installation guide.
