Actom Outdoor AIS Disconnectors

Features

Our simple yet robust design enables easy inexpensive installation, maintenance and operation.

All pivots are bushed with self lubricating or graphite nylon bearings.

The main swivel bearing incorporates twin taper roller bearings, grease filled and sealed for life.

Only switch contacts require the usual lubrication, therefore maintenance is re- duced to a minimum.

The single side break disconnector and operating mechanism drives are fully universal and thus they are suitable for horizontal, vertical or inverted mounting on concrete or steel support structure.

The single side break disconReverse loop design fixed contact fin- gers of HD HC copper with silver plated contact area. Each finger is backed by a stainless steel compression spring to ensure positive contact pressure, the springs being insulated from the current path.nector and operating mechanism drives are fully universal and thus they are suitable for horizontal, vertical or inverted mounting on concrete or steel support structure.

Interchangeable moving contacts of HC extruded copper section, the profile designed for high density current and multi-point contact. A wiping cleaning action is produced by the opening and closing operations.

Terminal pads of aluminium alloy with standard 44-50mm slotted holes (NEMA or IEC standard ) four-hole fixings as required. Terminal connectors can be provided if required.

Aluminium main blade tube wall thick- ness to suit current rating clamped into hinge contact assembly.

The Single side break has one fixed contact and one moving hinge. The hinge has a pivot pad assembled with sintered bronze bushes for self lubrication.

Alternatively, an enclosed hinge contact assembly incorporating a copper alloy terminal stem as opposed to a terminal pad, point contact.

Rotating post main bearing assembly in-corporating well spaced double taper roller bearings, preloaded to compen-sate for heavy high voltage insulators . The housing is packed with grease on assembly and sealed for life, thus eliminating further maintenance.

All Disconnectors and Earthing Switches are made by ACTOM High Voltage Equipment under licence to Lucy Electric, Banbury, United Kingdom.

History

Our range of Double Break Disconnectors are designed to ensure the highest performance.

With reliability resulting from over 30 years experience.

Over 35,000 disconnecting switches have been installed in South Africa, countries in Africa and some abroad.

We guarantee our product for long term, easy installation, low maintenance.

Basic Design

The DSB Disconnector is installed for sectionalising and isolating various circuits and equipment in substation systems.

The double side break operation is electrically superior to the single side break in so far as phase spacing is concerned, because two breaks in the series per phase are achieved.

This produces a neutral potential switch blade and permits minimum phase centre mounting.

The Double break Disconnector and manual operating mechanism drives are fully universal and therefore suitable for horizontal or vertical or inverted mount.
