Product Description

300KVA 3 Phase Autotransformer Distribution Transformer

Product Introduction

Our 300KVA 3 Phase Autotransformer Distribution Transformer is a premium, energy-efficient industrial power solution, purpose-built for global industrial and commercial voltage distribution needs. This dry-type transformer is perfectly suited for factory power systems, CNC machine tools, laser cutting equipment, photovoltaic (PV) systems, power transmission infrastructure, voltage test benches, EV charging stations, generators, motors, elevators, medical equipment, AI data centers, and precision industrial devices. As a professional China-based transformer manufacturer, we deliver fully customizable configurations to meet regional and project-specific requirements, with strict adherence to international quality and environmental protection standards.

Key Features & Advantages

This 300KVA 3 phase autotransformer delivers industry-leading performance with core strengths including 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 a working efficiency of ≥90% to reduce long-term operational costs.

We use high-purity winding material for superior electrical conductivity and low heat generation, paired with high-grade insulation materials that withstand 3500V dielectric strength tests, a Class F insulation rating, and a heavy-duty nylon insulation frame for maximum safety. The transformer features reliable high-insulation terminals, a robust and durable structure, 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 for flexible mobility, with zero additional waveform distortion to protect sensitive equipment.
