BLUESIL Fluid 604V50
High-purity dielectric PDMS specifically for transformer insulation and medium-voltage systems.
BLUESIL Fluid 604V50 is a dielectric fluid made of polydimethylsiloxane, whose purity has been specifically tested for electrotechnical applications. It serves as an insulating and cooling medium for transformers and, more generally, for medium-voltage equipment such as switchgear, chokes, capacitors, and resistors, particularly where environmental or fire protection requirements exist, for example, in public areas, basements, or near bodies of water. The fluid offers excellent dielectric properties, high thermal stability, chemical inertness, good heat transfer, and is non-flammable.

Frequently asked questions about Fluid 604V50
Practical application and design questions — answered by SILITECH.
Bluesil Fluid 604V50: High-purity dielectric PDMS (50 mm²/s) specifically for transformer insulation and medium-voltage installations — non-flammable, chemically inert, and environmentally friendly. Main applications: transformer insulation, medium-voltage installations, public utilities.
PDMS (Polydimethylsiloxane) is a linear silicone fluid with high thermal stability, low surface tension, very good dielectric properties, and broad temperature resistance. The viscosity (in mm²/s = cSt) determines the field of application — low viscosities for volatile lubrication and hydraulics, high viscosities for antifoam, damping, and care conditioning.
Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
