400KVA 3 Phase Marine Voltage Transformer
Product Introduction
Our 400KVA 3 Phase Marine Voltage Transformer is a heavy-duty, high-reliability dry-type power solution, engineered for stable voltage conversion in harsh marine and global industrial environments. Purpose-built for shipboard power systems, factory power distribution, CNC machine tools, laser cutting equipment, photovoltaic (PV) systems, power transmission infrastructure, voltage test benches, EV charging stations, generators, motors and precision industrial devices, it serves electrical engineers, industrial factories and electrical sector clients worldwide. Manufactured in Shanghai, China, this transformer supports fully customizable voltage, power and configuration to meet regional marine and industrial standards, with strict compliance with international environmental protection and safety regulations.
Key Features & Advantages
This 400KVA marine transformer delivers exceptional performance with full-capacity continuous operation, ultra-low temperature rise (<80K) and minimal energy losses. Its energy-saving design integrates a high-permeability new silicon steel core, enabling noise-free operation (<55dB), high magnetic flux and ≥90% working efficiency to cut long-term operational costs. We adopt high-purity winding material for superior electrical conductivity and low heat generation, paired with high-grade insulation materials that withstand 3500V dielectric strength tests, Class F insulation rating and a heavy-duty nylon frame for maximum insulation performance. The unit features reliable high-insulation terminals, a robust corrosion-resistant marine-grade structure, strong electrical conductivity and a user-friendly wiring design for simplified installation. Additional smart features include a digital display for real-time working status monitoring, clear data readouts, input/output indicators, a safety trip lock, optimized heat emission holes and braked universal wheels, with zero additional waveform distortion to protect sensitive marine and industrial equipment.
