SpanGUARD Rovel ABS - Installation

EASY INSTALLATION

As shown in Fig. 1 and Fig. 2, the ROVEL ABS Plastic material is flexible enough so that the installer can open the near side clam shell wise, slide the marker over the line and wrap the Preform HeliRods around the line on each side of the marker by hand.

The near side HeliBolts are already in place and an air drill or wrench is used to tighten the bolts and complete the installation in a very few minutes.

EHV INSTALLATIONS

Standard SpanGUARD line markers without EHV coating treatment have been used very successfully when mounted on the power line up to 220KV or when mounted on the static or ground wire of high voltage systems.

Tests have revealed that above 220KV, corona starts to develop at sharp edges and flanges. Therefore, the 24" and 36" EHV without flanges and with a special corona-free inside surface coating, has been developed.

The EHV coating is recommended for all installations where the marker is to be mounted on an energized power line above 200KV E7-iV models have been successfully installed directly on 500KV lines.
