Product catalog summary

Introduction
Mersen supports modern power generating equipment with high-speed carbon brushes, specifically the LFC554 grade, designed for strength, flexibility, and reliability.

Specifications

Density: 1.26
Resistivity: 2,000 µΩ.cm (787 µΩ.in)
Flexural strength: 11 MPa

Advantages of LFC554 Carbon Brushes

Lightweight with high strength and performance for energy efficiency.
Excellent damping and lubricating capabilities, leading to extended brush life and low wear.
Very low and stable friction coefficient, ensuring mechanical stability up to 100 m/s (328 ft/s).
Low electrical resistance for cooler operation and homogeneous current distribution.
Current density range: 7 to 13 A/cm² (45 to 84 A/in²).

OEM Approvals
The LFC554 carbon grade is approved by major OEMs such as GE, Siemens, Alstom, BHEL, Melco, Toshiba, and others.

Applications
Used in turbo generators, the LFC554 carbon brushes ensure full safety when replacing under load, reducing maintenance and downtime.
