Creating durable, cost-effective, environmentally friendly roofing and waterproofing materials is one of the most urgent tasks of civil and road construction. In the past years, a variety of methods were used to try to solve this task, until the application of bitumen emulsions came to the fore. Their popularity in roofing, waterproofing and road worksRead More
Hydraulic oil purification is a mandatory technological operation that must be performed before pouring such oil into equipment and periodically during oil operation. In most cases, hydraulic oil is used in the equipment which is sensitive to contamination. Terefore, the defined technical requirements for these fluids are clear enough, and product manufacturers try to complyRead More
Power transformers are the most expensive part of electric networks equipment. Perhaps this is why a large amount of such equipment has already exceeded its estimated service life. Not every electric power company can afford spending lots of money on transformer replacement. Therefore, the task of improving reliability of the existing fleet of power transformersRead More
Petroleum oils are chemically aggressive substances which are able to interact with other materials under certain environmental conditions. Incineration of waste oil can lead to emission of undesired components into the atmosphere (sulfur oxides, carbon oxides, nitrogen oxides, dust, ash, soot, etc.). The substances contained in waste oil can cause serious diseases, as well asRead More
Quality of transformer oil is an unstable property which is caused by the influence of a number of negative factors. Oxidation may be considered the most significant factor. The impact of sunlight, high temperatures, as well as some other factors contributes to the development of transformer oil oxidation. As a result, acids may form inRead More
Petroleum oil is essential in many industries, performing heat dissipation, lubricating, protective and other functions. But during operation, they are affected by many negative factors, which include friction, exposure to high temperatures, atmospheric oxygen and mechanical dirt particles. As a result, the oil begins to lose its properties and can not fully carry out itsRead More
Much attention in the European Union (EU) is traditionally paid to the issue of recycling of waste of different origin. Waste petroleum oil is no exception. When released into the environment, it can cause the death of animals, contamination of ground and drinking water, as well as the violation of virtually all biological links inRead More
World reserves of oil decrease over time, which makes the issue of used oil economy quite a pressing challenge. When considering the process of diesel fuel consumption, we should note that the problem of its saving must be addressed at three levels: at state level, at major consumers’ level and ordinary consumers’ level. GovernmentRead More

The seminar will include a discussion of transformer reliability and life extension, as well as purification and regeneration of transformer oil. The event will be held at Santo Domingo del Cerro, Edificio EfraínRead More
The December 2018 issue of Windpower Engineering & Development magazine published an article titled How to maintain wind-turbine gearbox & oil health, written by GlobeCore service engineer Frank May. The article deals with typical wind turbine gearbox issues, with an analysis of the factors detrimental to gearbox operation and reliability. The main idea is thatRead More
On 16-27 December 2018, GlobeCore specialists visited Saudi Arabia. The visit was dedicated to the issues of the Saudi electricity industry and efficiently addressing such problems. Specifically, GlobeCore equipment presentations were held in the cities of Jeddah, Medina, Jizan, Abha etc. The structure of the presentations varied depending on the specialization of the company hostingRead More
Our dear customers, partners and friends! We at GlobeCore wish you a very Merry Christmas and a Happy New Year. We appreciate your trust and the work we do together. Let the coming 2019 bring us new opportunities, original ideas and exciting projects for us to work on together. We have achieved much in theRead More
Contaminant Composition Aging of mineral oil occurs due to accumulation of contaminants with adverse effects on the operation of engines and machines. When motor oils become contaminated, the wear of the piston engine parts and carbon deposition increases, oil conduits and filters become clogged, normal operation and temperature of friction parts and the engine areRead More
Rapid degradation of transformer oil quality may occur not only due to insufficient chemical stability, but also due to the influence of construction and insulation materials used in a transformer. The most active catalyst of transformer oil oxidation is copper. The opinions of researchers regarding the influence of iron, aluminum, nickel and zinc are divided.Read More
The reliability of high voltage transformers in severe operation conditions is mainly defined by the quality of insulation oil. Mineral transformer oil is widely used for cooling and electrical insulation in oil-filled electrical systems. Transformer oil is a product of crude oil refining, and its chemical composition is largely determined by the hydrocarbon composition ofRead More
Power distribution and supply systems rely on transformers, which convert voltage and amperage at the same frequency and at the same power. Reliable transformer operation depends on the condition of its insulation system, which consists of cellulose insulation and dielectric oil. Such oil is also used in other electrical equipment, such as switches, cables etc.Read More
In many countries around the world today most of the transformers in operation were commissioned in the end of the previous century. That is why the issue of equipment replacement or lifetime extension is becoming important now. Power generation and distribution facilities must make decisions on the future strategy of improving the reliability of operatingRead More
This article is about oil reconditioning and the equipment required for this process. Let us first consider the basic types of modern industrial oil, their purposes and application. Classification of oils in the industry The main application of oils is lubrication of internal combustion engines. Depending on the purpose, the oils are classified as follows: dieselRead More
