Switchgear is an electrical equipment unit capable of disconnecting or connecting electrical circuits under both normal and abnormal conditions to ensure the reliability of the power service system. Issues with switchgear can include:

• Fingers rubbing against each other can turn black and burn
• Formation of crust
• Short switchgear lifetime, only 2 to 3 months
• Unexpected downtime due to sudden switchgear failure

Solution

To prevent the formation of crust or blackening that can result in unstable current and short circuits, a conductive lubricant is necessary. The lubricant must meet the following requirements:

• Can reduce electrical resistance and has good conductivity
• Can dissipate heat effectively, thereby reducing the risk of hot spots
• Does not melt, providing maximum protection to the contact finger
• Can function well as an electrical grease conductor, not causing shorts when switching on/off
• Can extend the lifetime of the switchgear

For this, Eonchemicals introduces the solution product Molykote HSC Plus lubricant. This lubricant not only meets the above requirements but also offers additional benefits:

• Can be applied at temperatures ranging from -30°C to 1100°C
• Remains stable and unchanged even at high temperatures
• Has excellent conductivity and rust protection

Success Story

Steps for applying the lubricant to switchgear:

• Clean the fingers on the switchgear using a solvent cleaner
• Apply Molykote HSC Plus to the cleaned switchgear fingers

Application Results

Results after approximately 3 months of running with Molykote HSC Plus applied to the contact fingers:

• The grease withstands high temperatures without melting, thus providing protection to the contact fingers
• Functions well as an electrical grease conductor, not causing shorts when switching on/off
• Extends the lifetime of the switchgear
