Oil filtration in on-load tap changers (OLTC) is crucial for several reasons: it maintains the dielectric strength of the oil, preventing electrical breakdown; it removes particulate contaminants that can cause wear and damage to contacts; it reduces moisture levels, which can lead to corrosion and insulation failure; and it enhances the overall reliability and lifespan of the OLTC. Regular oil filtration helps ensure optimal performance, minimizes maintenance costs, and prevents unexpected failures in transformer operation.

It is a fluid designed to withstand extreme heat while providing effective insulation and cooling in transformers.

FR3 oil is used for insulation and cooling in transformers, offering fire resistance and environmental advantages.

Antistripping agents are additives that enhance the adhesion between bitumen and aggregates, reducing moisture-induced damage (stripping). By improving the bond, they prevent water from weakening the pavement structure, thereby increasing durability and extending the asphalt’s service life.

Cationic bitumen emulsions contain positively charged bitumen droplets stabilized by cationic emulsifiers. They are known for their rapid setting and strong adhesion to a wide range of aggregates. Characteristics include good coating ability, even at lower temperatures, and compatibility with moist aggregates. Cationic emulsions break upon contact with the aggregate surface, facilitating quick curing. They are widely used in surface dressing, tack coats, and cold mix applications where fast setting and strong bonding are required. Their versatility makes them popular in various climatic conditions.

Midel oil is used in substation transformers to provide enhanced insulation and cooling while improving fire safety and environmental sustainability. Substations located in urban areas, near sensitive environments, or in fire-prone zones benefit from the non-toxic and fire-resistant properties of Midel oil.

Hydraulic Oil Environmental Impact plays a crucial role in the selection of hydraulic fluids for sustainable operations by prioritizing oils that minimize ecological harm and support environmental stewardship. Organizations increasingly choose bio-based hydraulic oils or biodegradable fluids to reduce the environmental footprint, as these oils break down more easily in the environment and pose less risk to ecosystems in case of leaks or spills. Low-toxicity formulations are preferred to protect both the environment and human health, ensuring safer handling and disposal. Additionally, oils with longer service lives reduce the frequency of oil changes and waste generation, enhancing operational sustainability. Eco-friendly additives that enhance oil performance without introducing harmful substances are also favored. Regulatory compliance is another factor, as environmental regulations may mandate the use of certain types of hydraulic fluids to limit pollution and promote greener practices. By considering the environmental impact, organizations can select hydraulic oils that not only meet performance requirements but also align with sustainability goals, thereby contributing to more responsible and eco-friendly hydraulic system operations.

Gas removal from silicone oil is typically achieved through vacuum degassing, where the oil is subjected to low-pressure conditions that cause dissolved gases to vaporize and be extracted. This process is important because dissolved gases, especially oxygen and combustible gases, can decrease the oil’s dielectric strength and increase the likelihood of electrical discharges. Removing these gases enhances the insulating properties of the oil, improves transformer safety, and prevents potential operational issues related to gas accumulation.
