A set of electrical transformers, capacitors and resistors using silicone based technology



Silicone for dielectric applications

Silicones are extremely efficient as insulation and cooling materials for electrical transformers and power distribution equipment, such as switch boxes, chokes, capacitors and resistors. They are especially reliable in sensitive environments - public places, densely-populated areas, hard-to-reach locations – where they play a critical role in protecting people and property because they offer thermal stability, higher flash and ignition points and less heat and smoke emissions in case of fire.

Elkem Silicones has developed a full range of ingredients and formulations, including Bluesil™​ oil for submerged transformers, to insulate and cool high and medium-voltage electrical equipment. These products offer:  

  • Excellent dielectric properties, as well as thermal and aging stability

  • Chemical inertia and strength

  • Efficient heat transfer properties over a wide temperature range

  • Lower flammability and ignition points

  • Less propagation, lower emissions and smoke in case of fire

  • Secure protection of critical spaces due to low heat spread

  • Environmentally friendly features and safety for people

Our experts are available worldwide to advise you and work collaboratively with you to find the solutions you need.
