Nanocomposites are new generation electrical insulation made up of nano-fillers mixed in a host insulation matrix. Such insulation technology has a potential for tailor engineering the properties to desired specifications. This paper presents a review of the nanocomposites insulation technology followed by an account of the experimental method and results of a methodology used in synthesising mesoporous hollow carbon nano-sphere (MHCNs) fillers. The obtained nanoparticles are characterised using SEM, TEM, Raman spectra, Banauer Emmett-Teller (BET), and thermogravimetric analysis techniques. The MHCNs have a diameter of $383 \pm 14\ \text{nm}$ and BET surface area of 341.5 m2/g. In the ongoing research, the synthesized MHCNs are then used as fillers to fabricate a C\Epoxy nanocomposite.
