Abstract

The dependence of electrical breakdown strength on rate of change of voltage between the electrodes is investigated for VHB4905, a very common polyacrylate adhesive tape produced by 3M with interesting dielectric properties. If voltage is applied according to a quasistatic loading protocol, it was found that the dielectric strength of VHB4905 can increase from 35 to 70 kV/mm, depending on the value of uniaxial deformation in the considered range, namely 0500%. In the case of a pulse voltage, the dielectric strength depends on the voltage intensity at the leading edge of the pulse. In particular, for the considered duration of the leading edge of the voltage pulse (~20 ns), a breakdown strength threshold has been found, which is 3.7 times larger than the quasistatic counterpart.
