A professional enterprise specializing in the production of various reactors, power transformers, dry-type transformers, amorphous alloy transformers, special transformers, and box-type substations. Equipped with modern production facilities and advanced manufacturing processes, we ensure high-performance products featuring low losses, low temperature rise, low noise, and strong short-circuit withstand capability.
The oil transformer offers outstanding efficiency and reliability. It provides high-efficiency power conversion, minimizing energy losses. With excellent voltage regulation, it maintains a stable output even under varying load conditions. The internal oil acts as both a coolant and an insulator, effectively dissipating heat and ensuring continuous operation without overheating. It also features high short-circuit withstand capacity, protecting the system from damage.
Our manufacturing involves advanced lamination of high-quality silicon steel sheets to reduce eddy current losses. Coils are wound tightly using precision machines and impregnated with special insulating materials. The transformer tank is leak-proof and treated for surface protection. We use high-grade copper or aluminum conductors and specially formulated mineral or synthetic oil with high dielectric properties.
Designed for ground-level installation on concrete pads, these self-contained units enclose the core, windings, and protection devices within a rugged, weather-resistant enclosure. This enhances safety and protects components from environmental factors like rain, snow, and dust.
