Product Features
1. High-Efficiency Iron Core
- Premium Material: Manufactured using high-quality crystal grain-oriented silicon-steel sheets.
- Precision Engineering: Utilizes the German GEORG cross-cut shear for a precise 45° joint seam.
- Optimized Performance: The multistage roll cross-section design effectively reduces operating noise and power consumption.
2. Robust Coil Design
- Structure: High-voltage (HV) coils use a cylinder type, while low-voltage (LV) coils utilize either cylinder or foil type structures.
- Durability: Enhanced ability to resist short circuits and lighting strikes.
- Rational Path: Engineered for a more rational magnetic path distribution to ensure stable operation.
3. Advanced Corrugated Oil Tank
- Manufacturing: Produced on a GEORG corrugation oil tank production line using fine cold-rolled steel sheets.
- Environmentally Ready: Coated with antiseptic materials, making it suitable for harsh environments like petroleum and chemical industries (resistant to oil stains and chemicals).
- Smart Compensation: The corrugated fins provide excellent heat radiation and automatically compensate for oil expansion and contraction.
- Air Isolation: The fully sealed design prevents oil aging and increases life expectancy.
4. Superior Insulation Structure
- Insulation Class: Adopts A-level insulation standards.
- Concentric Design: HV and LV coils are arranged concentrically with a cardboard sleeve small oil clearance partition structure to ensure high dielectric strength.
