High-Current Switch Grease

SEIVIO Swilub F738 High-Current Switch Grease is based on fully fluorinated base oil and a PTFE thickener. It is developed to protect electrical switch contacts, circuit breakers, sliding contacts and silver, silver-plated or gold-plated contacts exposed to arcing, high currents and high temperatures.

• Resists high-temperature arc degradation without leaving carbon residues that increase contact resistance.
• The uniform bond-energy distribution of the PFPE backbone provides resistance to high-energy arc-particle bombardment.
• Stabilizes contact resistance and prevents surface oxide formation and excessive heating.
• Helps shield copper and silver-plated contacts from SF6 decomposition products such as HF and SOF2, moisture and salt spray.
• Combines high dielectric strength against insulation breakdown with an ultrathin conductive film when contacts close, supporting stable long-term contact resistance.

For high-voltage SF6 circuit breakers above 60 kV, high-current disconnectors and vacuum circuit-breaker contacts. Also suitable for high-current sliding contacts in distribution cabinets, high-power relays and contactors, high-power vehicle switches, industrial power-transfer switches and precious-metal sliding contacts, including high-power electrical contacts in outdoor, humid or sulfur-corrosive environments.
