Our silica sol is used for various motor application to improve electrical insulating properties.
Breakdown time can be extended by adding nano silica.

Effect of nano silica on breakdown time
Testing method

Voltage:20kV(AC)
Frequency:200Hz
Temperature:20℃
Atmosphere:Air
Voltage eundurance test result

Resin:Bisphenol F type epoxy resin
Hardener:Acid anhydride
- Breakdown time was significantly extended
by adding Nissan's ORGANOSILICASOL to epoxy resin.
Electrical treeing properties
Testing method

Distance between electrodes:2mm
Applied voltage:25kVrms
Electrical treeing test resultThis data was provided by Murakami laboratory (Toyohashi University of Technology).

Resin:Bisphenol F type epoxy resin
Hardener:Acid anhydride
Particle size:12nm
- Propagation of electrical treeing was suppressed
by adding Nissan's ORGANOSILICASOL to epoxy resin and
increasing nano silica content.
Creepage discharge properties of epoxy/silica nano-composite in mineral oil
Testing method
Creepage discharge test resultThis data was provided by Kozako laboratory (Kyushu Institute of Technology).

Resin:Bisphenol A type epoxy resin
Hardener:Acid anhydride
SiO2 content:3wt%
- Creepage discharge was suppressed by
adding Nissan's ORGANOSILICASOL to epoxy resin.
Smaller particle size showed
a greater suppression effect.
