Corrosion Of Electrical Components

  • Left: Docklands Light Railway
  • Electrical components, wiring and stray current corrosion is a real problem in electrified rail systems and Light Rail Transit Systems. Stray-current corrosion occurs at the point where the current leaves the connector, carrying iron ions that became positively charged when they lose one or more electrons. The damage is unseen but the effect can be major. A 1-ampere current discharging continuously from a steel pipeline will remove approximately 20 pounds of steel in a year.
  • Since many LRTs are located in crowded utility corridors and in city streets with gas and oil pipelines and other underground utilities and structures, uncontrolled stray current can cause extensive damage to rail and concrete reinforcing steel, cables, and pipelines. By one estimate, stray-current corrosion damage in the U.S. may total over $500 billion annually.

Treated Control Switch

Case Study

  • LEFT 1: Badly rusted Control Switch untreated: Electrical failure after 100 hours salt spray.
  • LEFT 2: Switch treated with SuperCORR A. Electrical failure after 1400 hours salt spray.

The photographs demonstrate how SuperCORR A lubricates and protects switches in the most hostile environments.   The tests shown were carried out under controlled conditions in a hot salt spray which accelerates the results, full test details here.

It is clear that the use of SuperCORR A in regular maintenance procedures can bring financial savings in reduced maintenance and replacement costs and more importantly greater safety.

Amtrak train

Case Study

  • LEFT : SuperCORR A is used by Amtrak.
  • Amtrak tested SuperCORR A and reported an impressive improvement in the mating of 480V car jumpers with excellent protection for connector pins and lugs with no corrosion, overheating or electrical pitting over six months. Preventive maintenance from one can has all but eliminated failures of lubrication and reduced maintenance costs on demanding passenger trains.

Corrosion Protection For Railways And Transportation

Snow and rain mixed with road salt subject all electrical and close tolerance mechanical assemblies such as bearings, actuators, airline connections and high voltage mating jumpers on trains and trucks to extreme conditions. The failure of any of these components present potential dangers to equipment and passengers.

Specially Formulated Anti-Corrosive Inhibitors

  • SuperCORR A lubricates and protects switches in the most hostile environments which are likely to be experienced in the transportation industry.
  • Unexcelled in preventing deterioration and contamination on all surfaces of
    electronic and electrical equipment and mechanical close tolerance moving components.
  • Designed to protect and lubricate connectors, terminations and electrical bonds and grounds, relays, fittings, circuit boards, computers, from moisture, general and fretting corrosion, surface static electricity, corona, and other electro migration problems. Other areas of application include Passenger Master Control Panels, interior and exterior light sockets and any exposed metal surfaces.
  • Eliminate premature failure of components created by moisture, general or fretting corrosion. Reliability is increased, maintenance intervals increased, costs reduced and manufacturers can save on maintenance and repair costs .
  • SuperCORR A  prevents corrosive damage to electronics and other metal surfaces caused by exposure to fresh and salt water moisture. SuperCORR A  has gone through extensive Class III Mixed Flow Gas Testing and was found to also protect metals from the corrosive damage caused by Sulfur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia (NH3), and Chlorine based gases (CL12)
    gases. SuperCORR-A will also protect electronics against the very corrosive thermal decomposition by product of HFC-227ea fire suppression systems, Hydrogen Fluoride (HF).
  • An ultra-thin film of SuperCORR A  will not only prevent moisture from coming in to contact but will displace moisture that is there already.
  • SuperCORR A  is hydrophobic, that is it repels water and forms an airtight seal preventing damage to electronics and other metal surfaces caused by exposure to acid gases such as Sulfur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia (NH3), Chlorine based gases (CL12), and the thermal decomposition by product of HFC-227ea used in fire suppression systems, Hydrogen Fluoride (HF).
