Sightglasses get approval for marine applications

A Hawk IR International product story
Edited by the Engineeringtalk editorial team Apr 11, 2006

Sightglasses classified by Lloyds for use in marine switchgear running at up to 11kV can be permanently installed into electrical equipment to assess and monitor live components within switchrooms.

The latest C-Range Hawk IR Sightglasses are the first of their kind to be classified by Lloyds of London for use in marine switchgear running at up to 11kV.

Permanently installed into electrical equipment, the sightglass enables thermographers to assess and monitor live components within switchrooms on board.

Lloyds of London has granted approval to Hawk IR International for use on extreme voltages due to the extensive arc-fault testing that has been performed on this product.

Having been tested to a current maximum of 40kA at 7.2kV to Ansi C37 and tested to IEC62271-100/200 the latest sightglass is precision manufactured from aircraft grade aluminium, using low smoke and fume components required for offshore environments and incorporating the Clirvu broadband crystal optic - suitable for use with any infra-red camera - for increased strength and endurance.

The sightglasses are guaranteed for the life of their installation.

Third party testing includes prolonged cyclic humidity and vibration simulating severe on-board conditions throughout the ship, including engine room environments, allowing the sightglasses to be installed into switchgear and electrical equipment in virtually any location.

Extras include stainless-steel mountings, lexan and aluminium quick release covers.
