The operation and maintenance of disconnectors in power substations, require advanced lubrication solutions to ensure continuous and uninterrupted operation. In this article, we will explore the use of Krytox™ GPL205 lubricant in the power sector focusing on the customer benefits and operational challenges that can be solved by this product.
Introduction to electrical disconnect switches
Electrical substations often use high-voltage disconnect switches to regulate power flow and protect critical equipment. The disconnectors are filled with oil and the contacts are immersed in a liquid that acts as an insulator and prevents arcing. This oil is contained inside a metal casing.
Older models of disconnectors have an operating life of about 40 years, while modern versions last 30 years and are designed for easy maintenance and replacement.
Another type of disconnector is the SF6 disconnector, which uses sulfur hexafluoride (SF6) gas to interrupt the arc. SF6 is an inert, safe, nonflammable gas known for its excellent electrical insulation and arc extinguishing capabilities. SF6 switches are widely used in power grids, substations and industrial applications. However, both types of switches require effective lubrication to maintain optimal performance and reduce wear and tear.
Krytox™ GPL205: product presentation
Krytox™ GPL205 is a product used in the power industry for applications such as lubrication of seals, internal shafts and levers, as well as internal connections and couplings.
Its expected lubrication cycle is annual.
Key benefits include a significant reduction in downtime, long lubricant life, and the product’s ability to meet the contact resistivity requirements of the application.
Disconnectors: problems encountered with existing lubricants and requirements to be met
The use of Krytox™ GPL205 is very useful especially when these issues are encountered in the processing stages:
- General problems with the existing lubricant
- Frequent interruptions due to downtime
- Presence of an application process, requiring a lubricant that can demonstrate a high level of efficiency and chemical inertness in a small volume application.
Application and lubrication information and requirements
For the application of Krytox™ GPL205, the main lubrication points include rolling bearings and sliding surfaces. Krytox™ GPL205 meets all necessary requirements, such as chemical resistance, viscosity performance superiority, and corrosion protection. Its reliability makes it an excellent choice for applications requiring high performance in harsh environments.
Reliable performance and better benefits
The adoption of Krytox™ GPL205 leads to several benefits:
- Reduced downtime: With increased efficiency and long lubricant life, downtime due to unexpected maintenance work is dramatically reduced.
- Longer equipment life: Krytox™ GPL205 not only reduces friction and wear and tear, but also prevents corrosion and rust, thus ensuring an extended service life for critical equipment.
- Optimal performance: The lubricant meets the specifications required by different applications, offering excellent resistance to oxidation and stable viscosity over a wide range of temperatures.
This product ensures quality due to its versatility and, as mentioned earlier, meets all customer needs and eliminates costly unscheduled downtime.
Finally, no OEM qualifications or performance are required for this application.
Conclusion
Krytox™ GPL205 is an ideal solution for applications in the energy sector, thanks to its high performance and ability to reduce downtime and extend the life of equipment, particularly disconnectors.
Mascherpa is committed to offering quality solutions designed to meet the most complex needs in the operation and maintenance of disconnectors in electrical substations and, in general, in lubrication in the electrical field.
