Trusted Global Manufacturer of Toroidal Transformers
Founded in 1994, Torotrans has grown into a premier Small Scale Industrial (SSI) manufacturing unit located in Pune, India—just 180 km southeast of Mumbai's primary export ports. Spanning a specialized 3,500 sq. ft. manufacturing facility, we specialize in high-efficiency magnetic core components engineered to strict global standards.
We engineer and manufacture customized Toroidal Power Transformers (15VA to 5KVA) and Low Tension Current Transformers (LT CTs) in both tape-wound and resin-cast configurations. Global B2B buyers and OEM engineers rely on Torotrans for compact design, superior electrical regulation, minimal acoustic noise, and competitive factory-direct pricing.
Specialized Manufacturing Facilities
Our Pune facility is equipped with dedicated tools and automated winding machinery to maintain strict quality tolerance across OEM production runs.
Automated Winding Line
High-precision toroidal core & secondary winding machines capable of handling intricate wire gauges with uniform tension distribution.
Electric Annealing Furnace
Controlled electric heating furnaces for precise core stress-relieving and optimum magnetic permeability retention.
Rigorous Test Bench
100% full-parameter electrical test bench validating primary excitation, load losses, dielectric insulation, and ratio accuracy.
Key Technical & Operational Advantages
Toroidal transformers offer decisive structural and electrical performance benefits over traditional EI-laminated transformers, making them ideal for high-reliability applications.
Compact Footprint & Low Weight
Up to 50% smaller and lighter than conventional EI transformers, enabling sleek enclosure integration and reduced shipping costs for international exporters.
Zero Audible Hum & Low Stray Field
Continuous grain-oriented silicon steel cores eliminate air gaps, preventing mechanical vibration hum and reducing stray magnetic field emissions by 87%.
High Efficiency & Low Idle Losses
Optimized copper winding distribution minimizes copper and iron losses, yielding ultra-low no-load power consumption and superior electrical efficiency.
Thermal Dissipation & Regulation
Symmetrical winding around the entire core perimeter provides superior thermal radiation, lower temperature rise, and tighter voltage regulation under heavy load.
Industries We Serve Worldwide
Engineered for critical industrial, medical, and electronic applications where acoustic silence and power reliability are non-negotiable.
