SLD Series double insulator disconnector (isolator) is designed to be used on overhead distribution systems in a totally exposed environment and can be used as mechanical switching device which provides an isolating distance in open position. The SLD Series design provides strength and stability of double insulator design, positive latching to prevent accidental opening due to faults, line vibration, wind or other environmental influences. The straight fixed contact blades ensure smooth low effort operation and reduce wear on contact plating. The hinge end moving blade ensures the moving contacts alignment and proper engagement.

Construction

The standard porcelain insulators are light grey in colour and constructed from a single piece of glazed porcelain.

Porcelain insulators provide high creepage with 150 kV and 170 kV BIL insulation level.

Current carrying parts are manufactured from HD HC copper with 630 amp continuous rating. Moving contacts have ‘lead in’ feature and straight parallel sides to ensure low effort operation, reduce plating wear and ensure contact alignment during closing operation.

The hinge end is designed with separate contacts so that the current path is not through the joint and to provide blade alignment during the closing operation.

Terminal palms are bright tin plated to AS2395-1980 and are suitable for use with connectors, copper and aluminum compression lugs.

Mounting

The SLD series disconnector is designed for Underslung and Vertical mounting.
