1. Product Description
The 15KVA 50KVA 100KVA Three Phase Transformer is a compact, high-reliability power transformation series designed for three-phase AC power distribution systems. Covering three common small and medium capacity grades—15KVA, 50KVA and 100KVA—this three phase transformer lineup provides standardized voltage conversion and power adjustment for residential, commercial, light industrial and auxiliary power systems. Engineered according to IEC international electrical standards, the series features consistent structural design, stable output performance and low operational loss, making it a cost-effective universal power transformation solution for global low-voltage grid projects.
Each model in the 15KVA / 50KVA / 100KVA three phase transformer range adopts high-purity copper windings and high-quality grain-oriented silicon steel core materials. The optimized magnetic circuit structure effectively reduces no-load current, no-load loss and operating noise. With precise turn ratio calibration, the transformer delivers accurate and steady voltage step-up or step-down performance under rated working conditions. The whole series supports customized voltage grades and is available in both oil-immersed and dry-type structures to adapt to different installation environments, ensuring long-term continuous and trouble-free operation.
2. Core Purpose
The primary purpose of the 15KVA 50KVA 100KVA Three Phase Transformer is to implement safe, efficient and stable three-phase voltage conversion, power distribution and electrical isolation in low and medium voltage power systems. It converts grid voltage to standard usable voltage for terminal equipment, solves voltage mismatch problems in power supply lines, and suppresses grid voltage fluctuation and interference. This series balances line load distribution and improves the overall power supply quality of regional power grids.
As multi-specification basic power transformation equipment, the small-capacity 15KVA three phase transformer is mainly used for fine power distribution and auxiliary power supply, while the 50KVA and 100KVA medium-small capacity models undertake conventional load power supply and regional centralized power distribution tasks. All specifications provide reliable high-low voltage isolation, effectively prevent leakage current and short-circuit risks, protect downstream electrical equipment, and improve the safety, stability and economy of the entire power distribution system.
