Product Introduction

Products Description

Eco-Friendly Insulation Design
Features an anti-oxidation coated tank compatible with both mineral and eco-friendly insulating oils. Achieves a dielectric dissipation factor of ≤0.005 at 90°C, meeting essential environmental standards.

Full-Condition Stability
Designed for ambient temperatures from -25℃ to +45℃ (IEC 60076-12 thermal cycling verified), with humidity tolerance up to ≤95% RH (non-condensing). Certified to IP54 for dust and water splash protection and supports operation up to 2000 m altitude with derating (IEC 60076-15). Withstands 100 kA for 1 second short-circuit current (certified per GB 1094.5-2008).

Enhanced Dust & Moisture Protection
IP54 certified for dust and water splash resistance, with weld seam leakage ≤0.05 mbar·L/s. Operates reliably in environments with humidity up to ≤95% RH.

High-Efficiency Assurance
No-load loss ≤12 kW (compliant with GB 20052 Tier 1), and load loss ≤95 kW at 100% rated capacity. Supplied with factory-issued energy efficiency test reports.
