The quality of HILUBO transformer oils have been keeping the advanced leading level both in domestic and international industry. HILUBO has always been taking the technical innovation, absorbing experiences from the domestic industry, importing advanced technology, raw materials and formulations, producing products according to the international standards, such as IEC 296-91/revised, BS148-98 and ASTMD387. The products also conformed with the specifications GB2536-91 and SH0040-91.
HILUBO company has been managing not only the products of ourselves, also selling the transformer oils from foreign companies, Kalamayi refinery of Xinjiang Autonomous Region, and other special types of synthetic transformer oils. Since different transformers have different requirements, we think it's vital to offer products with characteristics that match the design and intended operating condition of each and every one of your transformers.
HILUBO transformer oils had been used successfully in many electricity enterprises, such as Lu Neng, Hu Neng, Northeast Electric Network, Northeast Electric Network, Eastern China Electric Network andSoutheren China Electric Network. The oils are used in many large volume transformers, also in many electric locomotives of the Railway Ministry. HILUBO transformer oils had been exported to Malaysia, India, Bengai, North Korea, South Korea, Singapore, Syria, Mongolic etc.
HILUBO people hope to make efforts with cooperators of electric system together, make more contribution for the development of china and the world electric industry.

Treatment |
|
ultra-high vacuum and proper high temperature
|
| The treatment using ultra-high vacuum and proper high temperature can decrease the content of the low molecular weight hydrocarbons, organic gas (including acetylene, methane, ethane, and so on), trace of water and air, which all effect flash point. Our factory controled water content below 5 g/g before products left factory and below 10 g/g when it arrived in the working site. |
| |
| High efficient adsorption |
| The adsorbent is a kind of material with many holes, large specific surface, strong ion exchanging performance, selective adsorption ability, hydrophilic property. This adsorbent can adsorb PCA (including asphaltene and neutral colloid), and some soluble mechanical impurities, such as sulfide compounds, olefin, naphthenic acid, basic nitrogen compounds, furfural and trace of water. So, it can improve the durability and light stability and decrease the corrodibility. The adsorbent can also adsorb heavy metal ions. |
| |
Filter
|
| Filter of non-oil mechanical impurities such as ash, metal particles and adsorbent left in the oil after oil refining is done to guarantee oily cleanliness (NAS< 3 degree). |
| |
On-site oil filling |
| |
| We do on-site oil filling to satisfy our clients' requirement. The oil is loaded in van to go to the spot as soon as the oil is qualified. We have 12 vehicles, 50 containers, 4 transfer stations special for transformer oil. Transformer oil can be shipped as containers with the transformer together. Special capsules (20 tones), tins (10-16.5tons), cans (200L) protected by nitrogen can be chosen. All these methods make the oil in high quality and can be filled on-site as soon as the oil gets to the destination. we also can stock up Nynas, American ERGON or other brands transformer oil from Singapore or Hongkong companies, and fill on site in Asia or Africa. |

Consultancy |
| |
The analysis results can sometimes require a more thorough examination. If this is the case, our experts perform a more complete investigation to find out more about the condition of your transformer. As an add on service, we offer a web tool that makes it easy to manage analysis data from all your transformers. With expert advice always available online, the tool will help fulfill your asset management strategy.

|
| Lower viscosity in low temperture |
|
| HILUBO transformer oils have outstanding physical and chemical properties such as low viscosity at low temperatures and high oxidation stability. |
|
| |
|
| High flash point |
|
| The higher flash point can be more aid to guarantee the safety for the storing and operating of the transformer oils. |
|
| |
|
| Lower water content |
|
| The exciting of very small amount of water will accelerate the aging tendency of the oil, reduce the safety of operating equipment and shorten the using life. HILUBO transformer oils are guaranteed with the water content no more than 20 ppm by factory test, lowest data be less than 5 ppm. |
|
| |
|
| Lower acid number |
|
| The HILUBO transformer oils are made by carefully selected deep refined naphthenic and isomeric hydrocarbon base oils. The acid number always is less than 0.01, lower than 0.03 , required by national standard. |
|
| |
|
| Better oxidation stability |
|
| Normally the service life of transformer oils can be extended to 30-50 years, the oxidation stability of insulation oil is quite important to the transformer for the long period operation. The HILUBO transformer oils has the best oxidation stability far ahead to most oils of other brands, and no means inferior to compare with the imported foreign transformer oils, applying HILUBO transformer oils can guarantee the transformer to keep safety operation with prolong using life and minimum running cost. |
|
| |
|
| Lower dissipation factor, higher breakdown voltage |
|
HILUBO transformer oils are all made by special technical process with quite strict management system, acomplete series of special production equipment, special transportion tank vehicles and special storage containers, had been built up to ensure the transformer oils keep the features of lowest dissipation factor and highest breakdown voltage. The typical data of the dielectric dissipation factor is always as lower as 0.0012, the breakdown voltage can be highest up to 50-60KV by factory test.
|
|
| |
|
| Optimum composition and lower gassing tendency |
|
| The HILUBO transformer oils are made by deep refined naphthenic base oils and incorporated with some isomeric alkanes and aromatic hydrocarbons, According to many years experience, with reference to the foreign and domestic research conclusion, we have well known the optimum incorporating ration of the cyclic alkanes, isomeric alkanes and aromatic hydrocarbons. HILUBO can produce transformer oils with various ration of cyclic alkanes and aromatic hydrocarbons according to the demands of customers to satisfy performance they needed. |
|
| |
|
| Good cleanliness |
|
| HILUBO transformer oils had exported abroad with large quantities, in order to satisfy the requirement of IEC-1991, super precision filtering process and strict storing-transporting management are kept on anytime to guarantee the huge cleanliness of transformer oils, and it's actually more superior than the IEC296 specification requirements. |
|
| |
|
Lower gas content |
|
| The gas content in the oils is very low, because the high vacuum Deaeration process and precise filtration treatment ensured the gas content of the transformer oils kept quite lower level. |
