Product Introduction
Our 500KVA 3 Phase Voltage Transformer (SG/SBK series) is a heavy-duty, high-performance dry-type power solution engineered for global industrial, commercial and renewable energy applications. With a standard rated capacity of 500KVA and a fully customizable range from 500VA to 2000KVA, it delivers stable, high-precision voltage conversion for 50Hz/60Hz AC circuits with operating voltage up to 1000V. Featuring a standard 220V input to 380V output ratio with fully customizable voltage configurations, it is the ideal 3 phase voltage transformer for low-voltage electrical equipment and power transmission control systems. Widely trusted by electrical engineers, factory operators and medical facility managers worldwide, it is perfectly suited for hospitals, factory power distribution, CNC machine tools, photovoltaic systems, power transmission equipment, precision instrumentation, generators, industrial motors and EV charging stations.
Key Features & Competitive Advantages
Engineered with premium raw materials and optimized design, our 500KVA 3 phase voltage transformer delivers exceptional long-term reliability and energy efficiency for continuous industrial operation. Core benefits include full-capacity non-stop operation under non-overloaded conditions, ultra-low temperature rise, minimal energy losses and an energy-saving, environmentally compliant design. It adopts a high-permeability silicon steel core for noise-free operation (<55dB) and high magnetic flux, paired with high-purity winding material for superior conductivity and reduced heat generation. High-grade insulation materials withstand 3500V dielectric strength tests, with a heavy-duty nylon frame ensuring stable insulation performance and Class H insulation grade for enhanced thermal stability. It features ±2% output precision, no additional waveform distortion, robust high-insulation terminals, safe and durable construction, and user-friendly wiring design, with SG (cabinet-enclosed) and SBK (cabinet-free) models for flexible installation.
