Quality That Protects Your Investment
Every coil and bar we manufacture is an investment in the long-term reliability of your infrastructure. Our rigorous quality and testing programme ensures that investment delivers decades of dependable service.
Obsessed with Quality
Manufactured for Reliability
For your generator or motor, the quality of every coil and bar directly determines how long the machine will run before the next outage. Over 50 years of continuous improvement in materials, processes, and testing has made us the partner that leading energy companies trust to protect their most critical rotating assets.
ISO 9001:2015 certified with ISO 45001:2018 and ISO 14001:2015 management systems. We manufacture to BS EN 50209:1999, ESI 44-5, and customer-specific standards -- with the international experience to meet regional requirements wherever your assets operate.

Our confidence in every coil we produce is your protection. Industry-leading test results backed by a guarantee that puts your long-term reliability first.
Testing Programme
Testing That Gives You Confidence in Long-Term Performance
Our obsession with quality means every coil and bar undergoes a rigorous battery of tests before it leaves our facility — no exceptions. These tests verify that your coils and bars will deliver the reliable, long-term service your infrastructure demands.
High-Voltage (Hi-Pot) Test
AC and DC withstand tests verify ground wall insulation integrity at voltages well above normal operating levels.
Surge Comparison Test
Detects turn-to-turn insulation weaknesses by comparing reflected surge waveforms between coil phases.
Tan Delta (Dissipation Factor)
We offer the industry's lowest tan delta levels, measuring insulation loss characteristics under voltage stress.
Partial Discharge (PD)
Industry-leading lowest partial discharge levels. Detects localised electrical discharges within the insulation system.
Dimensional Inspection
3D coordinate measuring machines verify that every coil and bar meets exact slot, overhang, and connection dimensions.
Insulation Resistance
Megger testing measures insulation resistance to ground at standard and elevated temperatures for long-term reliability.
Standards & Memberships
Compliance and Accountability You Can Verify
Our certifications and industry memberships ensure accountability and give you confidence that every coil and bar meets the standards your applications demand.
