Single Insulator Disconnect Covers

Avian and Wildlife Outage Mitigation

2 Models for
Aluma-Form & Hubbell Disconnects




Single Insulator Disconnect Covers are Outage Protection devices that are designed and tested to minimize animal related outages without compromising equipment performance. All of Rauckman’s animal mitigation devices increase reliability while decreasing unplanned interruptions of service.

Rauckman Covers for Single Insulator Disconnects help electric utilities minimize outages caused by animal interaction. The benefits are not simply the minimizing of outages, but also the mitigation of Avian interactions.

Single Insulator Disconnect Covers have increased in popularity due to convenience and economics. These devices are sometimes referred to as vertical or cutout disconnects. The Rauckman cover is easily installed and covers the energized components on the top of new or in-place switches.

Single Insulator Disconnect Covers incorporate load-break hooks to allow the use of a portable load-break tool. These tools are typically landed on these hooks from an appreciable distance so it is critical that a cover does not hinder this process.

Rauckman’s covers are field tested to ensure that the cover does not interfere with the use of these portable load-break tools.

There are two models available for Aluma-Form & Hubbell Power Systems disconnect switches.
