Energized Maintenance 

Whether using Distance Method or Potential Method, there is virtually no limit on the scope of maintenance services that can be offered to the Overhead Transmission Lines (OHTLs) on the energized mode. Counting on the proper equipment, experienced personnel and strict safety rules, heavy maintenance tasks for energized OHTLs components are safely performed, avoiding any collapse for any of these components that may lead to power failure which translates to financial losses.

Hot Washing 

Power insulators are continuously exposed to sand storms, salty fog, dense humidity and industrial pollution. Accumulation of contaminants results in water filming which eventually leads to leakage currents and flashovers. Routinely scheduled pressurized washing for energized power insulators eliminates the need for scheduled shutdowns. The overall efficiency of the network and the failure records are remarkably improved without any unneeded interruption for the power supply.

Silicone RTV Coatings

High Voltage Insulator Coatings (HVIC) are potentially the most reliable maintenance-free solution available for long term protection against pollution induced flashovers. Silicone RTV Coatings have superior field  track record in exhibiting Hydrophobicity and Long-term Weather Resistance. Hydrophobic surfaces prevent water filming by forming separate water droplets. Silicone RTV Coatings are also characterized by having strong resistance for UV degradation, water absorption and acid rain.

Thermal Imaging

Thermal Imaging is becoming one of the most important tools in Predictive Maintenance and Condition Monitoring. Thermal Imaging is the use of an infrared imaging and measurement system that can "see" heat emitted from an object. Thermal Imaging systems work because there is a direct relationship between temperature and pending failure in most plant equipment. Thermal Imaging can inspect quickly and effectively all indoor and outdoor components of the electrical systems with the system under load.
