<br />Allis-Chalmers IEads the indust�y in
<br />the development of hydraufic opera-
<br />tors `or disconnect s�itches. These
<br />easy to �nstail systems use flex cop-
<br />per tubing that is far simpler to put in
<br />tha� the usuai array of inechanical
<br />connections.
<br />Sdvings can also be realized with
<br />hyd��ul�c systems in cases of multi-
<br />p�e switch operation. For example,
<br />one motur-driven hydraulic operator
<br />can read�ly control up to six separate
<br />swi!�he5. You eliminate the problems
<br />�r��ith mechanical linkages . . . get bet-
<br />ter power ratins at the switch ... and
<br />minimi,ze any strain on the operating
<br />mechanism.
<br />In adclition to truly ePficient dis-
<br />connect sr.*it�hes and operators,
<br />Allis-Chalmers supplies . . .
<br />HIGH-SPEED GR,OUNDING
<br />SWITCHES
<br />For use wherever fast grounding is
<br />essential to protect against problems
<br />such as a transformer developing a
<br />low capacity fauit and damaging the
<br />system. Available spring loaded or
<br />propellant driven—from 15 to 500 kv.
<br />STRUCTURAL SUBSTATIONS
<br />We also provide complete structural
<br />substations, including switches, steel
<br />or aluminum structures, grounding
<br />mat�rial, bus, bus insulators, opera-
<br />tors, potential devices and other re-
<br />lated equipment ... all according to
<br />your exact specifications.
