I will assume this question was asked in the context of classical
thermodynamics.
In such a context "intensive" quantities pertain to the substance, but not to
the
extent, or size, of the system. Electrical conductivity is certainly in that
category *classically*, but in reality conductivity is dependent upon nonlocal
influences, and for systems with sufficiently small dimensions electrical
conduc-
tivity could certainly fail to satisfy the condition that it does not depend
upon
the size of the system.

This in no way relegates conductivity to the "extensive" category in such
cases.
