TEJADA, Víctor  and  PLEE, Dominique. Study of ceramic formulations for electricalinsulators. Rev. Soc. Quím. Perú [online]. 2016, vol.82, n.1, pp.72-86. ISSN 1810-634X.

The Peruvian company Cerartec S.A has developed ceramic-based electrical insulators for medium voltage lines. These products, ANSI 53-2 type (Spool and Guy Strain Insulators), are composed mainly of peruvian raw materials. Both formulationand process have an influence on residual porosities. Relevant parameters of formulation and process have been identified. In the investigated range, a linear relationship was drawn between porosities and flexural modulus of rupture. The new ceramic electrical insulators have been tested in terms of dielectric resistance, in dry and wet conditions.

Keywords : Electrical insulators; ceramics; electrical voltage; dielectric strength.
