Midsun IKM’s CEO, Imad Kanouni, made a video to go over the basic steps of every application process of high voltage insulator coating. He resumes that the RTV Silicone High Voltage Insulator Coating can be applied in 5 steps: surface preparation, mixing, application and drying.

1. Understanding the Importance of High Voltage Insulator Cleaning

Before delving into the practical steps, it’s essential to grasp the significance of high voltage insulator cleaning. These insulators act as the first line of defense against flashovers and electrical disruptions. Failure to maintain them can lead to reduced efficiency and, in extreme cases, catastrophic failures. Regular cleaning is the key to preventing the buildup of contaminants that compromise the insulator’s performance.

For insulators covered with silicone compounds or other types of greases, bulk of the silicone compounds or greases shall be removed with a dry abrasive cleaner or by hand wiping using solvent-dipped rags. Once the bulk of the grease has been removed, the surface should be wiped clean using an oil-free solvent.

2. Step-by-Step Guide to High Voltage Insulator Cleaning

Step 1: Safety First

Begin by ensuring that all safety protocols are in place. High voltage environments pose inherent risks, so it’s crucial to wear the appropriate protective gear, including insulating gloves and safety glasses. De-energize the system if possible and post warning signs to alert others.

Step 2: Visual Inspection

Conduct a thorough visual inspection of the insulators. Look for signs of contamination, corrosion, or physical damage. Identifying these issues early on can prevent more significant problems down the line.

Step 3: Dusting and Gentle Brushing

Use a soft brush or compressed air to remove loose dirt and dust from the insulator surface. Be gentle to avoid causing any damage. This initial cleaning step sets the stage for more intensive cleaning processes.
