Transformer oil VG
Composition and Properties
The composition of the components, determined by the operational requirements (given in GOST 982-80), includes:
- Base mineral oil, which first undergoes basic sulfuric acid and then selective purification.
- Antioxidant additive.
- Corrosion inhibitor.
The main physical and chemical characteristics of the oil:
- Density at room temperature, kg/m3 - 840 ± 5.
- Kinematic viscosity, mm2/ s, at a base temperature of 50 °C - 6… 7.
- Temperature range of application, °C - from -30 to +60.
- Boundary viscosity at pour point, mm2/s - 340.
- Acid number in terms of KOH, not higher - 0,02.
- Flash point °C, not less than 140.
These indicators fully comply with the global recommendations, which are specified in the ASTM D 4052 standard. Deciphering the brand abbreviation: C - high quality product, G - hydraulic cracking technology is used to produce oil (other brands of modern transformer oils, for example, GK oil are obtained in a similar way) .
Practical application
Due to the extremely low content of acid residue, VG transformer oil from Lukoil can be safely used in especially difficult operating conditions of transformers and other electrical devices for continuous operation. The composition of the components maintains a constant dielectric performance up to voltage values of 1,35 kV, which is typical for various start-control equipment of powerful engines, pumps, generators and ventilation systems. The product provides a stable temperature regime for devices such as large capacitors, industrial induction installations, current converters.
Characteristics:
- Prevention of electrical glow and arc discharges, which usually occur in the event of an uncontrolled increase in temperature in internal volumes.
- Thermal stability of the composition.
- Constancy of dielectric properties associated with the absence of free ions.
- High cooling capacity.
The modern technology for the production of transformer oil grade VG from Lukoil excludes the presence of any mechanical impurities and sediment during operation. Therefore, the labor intensity of maintenance of electrical installations using this product is significantly reduced.
Price per liter
The cost of transformer oil VG depends on the volume of purchase. Wholesale dealers ask for packing in 180 kg barrels - from 13000 ... .14000 rubles. Offers for the sale of this product at retail (in cans of 20 liters) are very rare. Usually the price per liter in such cases is 60 ... 80 rubles.
Judging by user reviews, the described transformer oil meets the expectations of consumers. Especially at elevated external ambient temperatures. When ordering, you should pay attention to the information on the manufacturer's specifications. The correct designation is TU 38.401-58-177-96, in other cases, poor-quality counterfeit goods are possible.
