In trelica bar for power machines

摘要

The insulation requirements of a lattice bar for inhibiting glow discharges can be reduced by providing longitudinal notches in the bending portions of the flat spacing conductors in the lattice bar. The notches can be provided on one or both sides of the spacing conductors in dependence upon the degree of twist of the conductors in the lattice bar. The extent to which the notches extend across the spacing conductors can also be a function of the degree of twist.
