Fluorosilicon Bearing Grease Improves Circuit Breaker Reliability

MOLYKOTE® Brand Smart Lubrication DuPont’s technology is enhancing the performance and reliability of electric utility high-voltage circuit breakers. Extensive field experience shows that lubricating breaker bearings with MOLYKOTE® 3451 chemical resistant bearing grease – a synthetic fluorosilicon oil thickened with PTFE – reduces failure rates and helps to avoid equipment damage and power disruptions There can be significant customer service and financial implications.

In utility circuit-breaker maintenance strategies, MOLYKOTE® 3451 Chemical Resistant Bearing Grease provides:

  • Longer lubricant life in harsh environments
  • Better wear and corrosion protection
  • Reliability under heavy loads, in extreme heat and cold, and with intermittent operation
  • High resistance to oxidation and drying
  • Prevention of sludge or varnish buildup

Poor or insufficient lubrication is a common cause of circuit breaker failures. Electric utilities that lubricate breaker bearings with synthetic fluorosilicon grease can help reduce failures and improve overall reliability. MOLYKOTE® 3451 chemical resistant bearing grease lasts longer in harsh environments than other oils and greases. It has been shown to be effective in preventing equipment damage, prolonging maintenance intervals and reducing power outages.

This fluorosilicon grease can help extend circuit breaker maintenance intervals to 20 years or more and reduce problems and costs associated with slow travel times or trip failure.
