Description
10MVA Industrial cast-resin pad-mounted transformers are large-capacity, fully enclosed dry-type power distribution devices specifically designed for harsh industrial environments. Their core features include:
Cast-Resin Insulation: High-voltage windings use epoxy resin vacuum casting technology, offering full insulation and maintenance-free performance, in compliance with IEC 60076-11 standards.
Pad-Mounted Structure: Suitable for outdoor installation, with an IP65 protection rating (dustproof and waterproof), and can be directly placed on concrete foundations.
Industrial-Grade Design: Capable of withstanding high-load impacts, harmonic pollution, and extreme climates (operating temperature range: -40°C to +70°C).
Power Conversion: Steps down medium voltage (e.g., 35kV) to industrial power voltage (6.6kV/690V) to meet the power supply requirements of large equipment.
Safety Isolation: Adopts an oil-free design (fire rating F1), suitable for inflammable and explosive areas, effectively reducing factory fire risks.
Harmonic Suppression: Equipped with an internal aluminum shielding layer, capable of withstanding total harmonic distortion (THD) ≤8% to protect precision industrial equipment from harmonic interference.
Overload Capacity: Supports 120% load for 4 consecutive hours and 150% load for 1 hour (in line with IEC 60076-12 standards), addressing peak production loads.
Iron and Steel Metallurgy: Powers arc furnaces, rolling mills, etc., with the ability to withstand frequent short-circuit impacts.
Chemical Parks: Adopts anti-corrosion design (316 stainless steel casing) to adapt to corrosive environments with hydrogen sulfide (H₂S), chlorine (Cl₂), etc.
Automotive Manufacturing: Used with frequency converter loads, suppressing harmonic interference by configuring 12% reactance rate.
PV/Wind Power Step-Up: Integrates DC component blocking function on the 35kV side, suitable for new energy power generation scenarios.
Data Centers: Pursues 99.99% power availability with dual-winding redundancy design.
Mining: Features seismic design compliant with EN 60068-3-3 Class 2 standards, adapting to underground vibration environments.
Ports: Adopts salt spray protection design, reaching ISO 9227 C5-M grade to resist marine climate erosion.
