ABSTRACT:
A section insulator for securing adjoining overhead contact wires for use by electric vehicles having a current collector, such section insulator including structural members to prevent destructive arcing caused by the passage of the current collector thereover. The structural members include first and second tension beams with replaceable arc shields mounted thereon, an adjustable center runner which can be lowered to compensate for wear, and arcing horns of a configuration to aid in the dissipation of electric arcs away from the structural members.
