Roads are reinforced with bitumen surfaces by integrating fibers or polymers into bitumen to enhance strength and flexibility. GlobeCore polymer-modified bitumen plants ensure precise additive integration, producing materials that resist cracking and deformation under heavy traffic and extreme conditions.

The optimal storage temperature for transformer oil is between 10°C and 40°C. GlobeCore tanks include temperature control systems to ensure oil quality.

Filters remove impurities from bitumen and water, ensuring a clean mixture. They protect pumps and mills from damage, maintaining the quality and longevity of equipment.

Midel oil helps prevent leaks by maintaining consistent viscosity and sealing properties over time. It does not degrade as quickly as mineral oil, which reduces the risk of gasket failure and seal deterioration. Additionally, Midel oil is compatible with most materials used in transformers, ensuring long-term stability.

Transformer fluid reconditioning refers to the process of restoring used transformer oil to its original condition by removing contaminants and replenishing its essential properties. In the case of silicone oil, reconditioning involves several steps to ensure the oil regains its insulating and cooling capabilities. The process typically begins with purification methods such as vacuum dehydration to remove moisture and degassing to eliminate dissolved gases. Filtration systems are then employed to remove particulate matter and tramp oils, ensuring the oil is free from solid contaminants. Adsorption treatments using materials like activated alumina or molecular sieves further extract acidic compounds and polar impurities that may have formed due to oxidation. After these purification steps, the oil may undergo quality testing to verify that it meets industry standards for dielectric strength, moisture content, and acidity. Reconditioning silicone oil extends its usable life, maintains transformer performance, and reduces the need for costly oil replacements, making it a cost-effective and environmentally friendly maintenance practice.

Silicone oil offers several advantages over other insulating fluids. Its high dielectric strength and thermal stability ensure effective insulation and cooling under demanding conditions. The oil’s low flammability enhances fire safety, making it suitable for installations where fire risk is a concern. Silicone oil also exhibits excellent chemical stability, resisting oxidation and degradation, which extends the service life of both the oil and the transformer. Additionally, its consistent viscosity across a broad temperature range ensures reliable performance in varying environmental conditions.

The dielectric strength of silicone oil is a measure of its ability to withstand electric stress without breaking down. High dielectric strength ensures effective insulation between the transformer’s conductive components, preventing electrical discharges and short circuits. If the dielectric strength decreases due to contamination or degradation, it can lead to insulation failure, resulting in transformer malfunctions or catastrophic failures. Maintaining high dielectric strength is essential for the safe and efficient operation of transformers.

Common causes of turbine oil leakage include:

Worn Seals and Gaskets: Over time, seals and gaskets can degrade, leading to leaks.
Improper Installation: Incorrect installation of components can result in gaps or misalignments.
Pressure Imbalances: Excessive pressure within the system can force oil past seals.
Contaminated Oil: Particles in the oil can cause abrasion of seals.
Thermal Expansion: Temperature fluctuations can cause components to expand and contract, affecting seal integrity.
Addressing leakage:

Regular Inspection: Monitor seals, gaskets, and fittings for wear or damage.
Proper Maintenance: Replace worn components promptly and ensure correct installation.
Pressure Management: Maintain system pressures within design specifications.
Oil Cleanliness: Keep oil clean to prevent abrasive wear on seals.
Temperature Control: Manage operating temperatures to minimize thermal stress.
Preventing leaks reduces oil loss, environmental impact, and potential safety hazards.
