SG (B) 10 Series Non-encapsulated Dry-type Power Transformers
Dry-type Power Transformers Our transformers employ cutting-edge European dry-type transformer technology, ensuring superior fire resistance, waterproofing, and environmental protection.
Through innovative structural optimization of the high-voltage coil,we enhance the voltage and capacitance distribution between layers, significantly boosting the transformer's resilience against atmospheric overvoltages.This also improves the performance against operating overvoltages and the distribution of electric fields. Ideal for diverse distribution systems, our transformers are paramount in subways, shipbuilding, mining, chemical industries, power companies, and high-occupancy buildings, fulfilling specialized safety requirements.

2. SafetyThe SG10 series power transformers prioritize safety, employing insulated materials that are both flame retardant and moisture-proof. Remarkably, the combustible content is limited to just 10% compared to epoxy resin transformers. Furthermore, even under prolonged exposure to 800ºC, these materials emit no toxic fumes.
3. ReliabilityReliability is a cornerstone of the SG10 series power transformers. They feature a special coil design and advanced technology that ensures protection against moisture, mold, and flame. This robust construction allows them to withstand high thermal shocks without any partial discharge, guaranteeing consistent performance.
4. Strong Overload CapabilityThe SG10 series power transformers boast formidable overload capability. They can endure 120% of their rated capacity and maintain prolonged operation under IP23 conditions without the need for forced air cooling.
