Transformer oils play a major role in increasing the efficiency of power and distribution systems and reducing potential hazards. Synthetic esters offer many advantages in terms of fire safety, insulation life, environmental sensitivity and usage cycle.
Transformers are everywhere. In today’s city structures, we need electricity for almost every kind of operation, even the smallest ones. To have electrical energy, we need electrical power transformers in every part of our lives.
For electricity generation, there are coal plants, nuclear plants, hydro plants, wind power plants and solar panels. The electricity generated at these plants is transmitted to consumers, which include heavy industry, but also railways, large factories, large buildings, commercial buildings and residential areas. There are many types of big and small transformers, changing the voltage of the electrical power and allowing access of electricity between the generation and consumer spheres.
Transformer stations are built in various areas from country sides to urban areas. Transformer failure is one of the main cause of power outages, but when they are located in city centers, in public buildings and sensitive areas, the other aspects of safety (voltage breakdown hazards, fire hazards and environmental impact) are becoming of paramount importance. Therefore, electrical power transformers need to be protected and isolated to prevent any threat.
Electrical power transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. These windings must be insulated for protection. Dielectric fluids are designed to protect the system from various hazards, and prevent any overheating.
In this area, mineral oils (such as naphthenics) have been used for decades but are displaying high risks of fire and environmental issues if spilled. Every day around the world, there is a dramatic fire event related to mineral oil filled transformer. Among the alternative fluids available on the market, Synthetic ester transformer oils remain the best choice in terms of fire safety and high performance in transformers and electro-technic systems, displaying a broad range of benefits.
Nyco produces synthetic ester-based dielectric fluids for transformers. Within the product range, the Nycodiel 1200 series offers excellent dielectric properties, high oxidation/thermal stability, fire safety, low temperature capability and high moisture tolerance. They are also environmentally friendly as these products are readily biodegradable with non-hazardous classification. This series is particularly suitable for installations located in sensitive areas such as rivers and lakesides, suburban, confined and restricted areas.
Nycodiel 1200 series has been successfully operated in traction transformers (EMU, VHST, tram-trains, locomotives, railway operators, etc.), windmill transformers, off-shore transformers, distribution transformers and many other areas. Nycodiel 1200 series has been qualified by several transformer manufacturers and accepted for use without restriction, providing excellent performances in service.
