NYCODIEL
NYCODIEL 1233
Biodegradable ISO VG 15 Dielectric Fluid. Delivers excellent low-temperature performance for all transformer types. Meets IEC 61039 O3 standards.
Discover
Particularly recommended for use in environmentally sensitive applications or where a high level of fire safety is required, NYCODIEL 1258 combines improved heat resistance, fire safety, and low temperature capability. Its excellent environmental profile makes it an ideal the replacement to mineral and silicone oils.
- 01 Excellent oxidation stability (IEC 61125 method C)
- 02 Meets IEC 61039 K3 fire safety class requirements
- 03 Biodegradability 84% (OECD 301B)
- 04 Not hazardous for the environment
- 05 MR VCUTAP®, DEETAP®, and COMTAP® tap-chargers approved
More information
Low temperature capability
With extra low pour point and low viscosity at low temperature, NYCODIEL® 1258 might be used at temperatures as low as -40°C.
High moisture tolerance
With high saturation limits, NYCODIEL® 1258 can absorb large quantities of moisture without impacting breakdown voltage. It enables slower ageing of transformers, extension of cellulose insulation life, reduction of bubble evolution during overloads and of condensation during cool down.
Retro filling and compatibility
NYCODIEL 1258 are fully compatible and miscible in all proportions with mineral oil, natural ester oils and other synthetic esters meeting the same specification but are not miscible with silicone oils.
