Mersen’s bronze SR 13-15 slip rings for GE 1.5-1.85 MW wind turbines deliver a 30-40% reduction in operating temperature, extend brush life, and provide a proven plug-and-play retrofit solution trusted in more than 4,000 installations across the United States.
Bronze Slip Ring Solutions for OEM & Retrofit
Wind turbine operators running GE 1.5MW, 1.6MW, 1.7MW, and 1.85MW platforms know the challenge well: heavier loads, boosted operating conditions, and years of continuous in-field wear push the original slip ring system to its limits.
As turbines age and output targets rise, the original stainless steel slip ring design - adequate at lower loads - becomes a liability rather than an asset. Mersen's

team has engineered a direct answer: the SR 13-15 bronze slip ring assembly, built to outperform legacy stainless steel designs across every measurable metric, from operating temperature to brush life.
The case for bronze: why stainless steel falls short above 1.5 MW
Stainless steel slip rings have a well-documented failure pattern in wind applications: at loads above 1.5 MW, especially under extreme ambient temperatures or boosted operation, they generate excess heat, accelerate brush wear, and contribute to NDE (Non-Drive End)
bearing temperature faults. The problem worsens as turbines are pushed toward higher output targets.
Bronze behaves fundamentally differently. The alloy is gentler on carbon brush contacts, dissipates heat across a wider surface area, and maintains consistent electrical conductivity under variable load conditions — precisely the demands of a modern wind generator running at boosted capacity.
