A conductor assembly, a conductor spacer and an associated method for separating conductors are provided in order to secure conductors to one another and/or to an underlying platform. A conductor assembly includes a spacer body having a prismatic solid shape, first and second conductors that extend alongside the spacer body and first and second ties for securing the conductors to the spacer body. The spacer body includes a pair of end faces and a plurality of side faces extending between the end faces. The spacer body also defines an internal cavity that is accessible via openings defined by the end faces and at least two of the side faces. The spacer body is configured to provide different spacings between the conductors when the ties extend through different ones of the openings.
