BIODEGRADABLE DIELECTRIC FLUID

Nycodiel 1244 is a dielectric fluid ISO VG 22 based on formulated high performance synthetic ester.

Nycodiel 1244 has been developed to fulfil the demand of the electrical industry willing to find a technical alternative to naphtenic based products

Nyco’s expertise in specialty ester synthesis associated with its knowledge in additive formulation allow us to offer a dielectric fluid matching the IEC 61099 standard.

Nycodiel1244 is used in transformer oil as coolant and for its dielectric properties. Nycolube1244 is also used as quencher for the sparks generated by the open electrical contacts.

  • Match IEC 61099 standard
  • Excellent oxidation stability(IEC 61125)
  • Very low water content
  • Biodegradability (OECD 301B)
  • NWG (UBA) (Not Hazardous to water)
  • Based on renewable raw materials

Biodegradable synthetic and natural esters are the good alternative for mineral oil,

especially in the situations when the power transformer has to be installed in the places for which the restricted environmental regulations are specified. Next to the many positive aspects like the higher biodegradability, high flash point and good properties concerning the AC electrical strength, esters have also negative features, which should be taken into account in the design phase and during the exploitation of the transformer with esters. The parameters of the designed transformer must be based on the knowledge about these negative features.

Designer should know that the esters are susceptible to the action of a concentrated heat flux, have the worse cooling properties than mineral oil, and lower lightning strength. The final product – power transformer filled by ester – will be in effect the more expensive device, but taking into consideration the pro-ecological tendencies reigned on the transformer market and still increasing demand for new environmentally friendly products, in the feature the cost will be certainly lower.
