Cable Spacer System
The key element of the Hendrix system is the spacer. The spacer is made of HDPE, which provides sufficient insulation for the phase separation of the conductors. The spacers hang on and are clamped onto the messenger wire.
The phase conductors are also held in place by clamps which are secured by simply closing the clamps onto the conductor. Previous experience has however shown that the spacers do move position over time and are affected by strong winds. For this reason, an anti-sway bar must be installed on every intermediate structure.
The positioning of the spacers is very important in correctly constructing a Hendrix system. The spacers maintain sufficient clearance between the phases and are designed to maintain the tensionless system. The spacers are used at intermediate structures and spaced evenly between spans.
