Abstract
A cable spacer of the type used in overhead power transmission systems includes a body provided with cable engaging hooks, each hook having a seat in the form of a cylindrical segment. A cable retainer is provided for each seat and consists of a cylindrical body having at least one semicylindrical groove and a handle projecting radially outwardly. The retainer is slidably receivable in the seat from either end thereof and rotatable between a first position in which the cable may be inserted into the groove and a second, cable retaining position in which the groove is within the confines of the seat.
Claims13
A device for holding power transmission cables in spaced relation to one another and to a messenger wire comprising:
- a spacer body having a first, messenger wire engaging hook at the upper end thereof and a plurality of second, cable engaging hooks spaced from said first hook and from one another, each of said first and second hooks having a seat in the form of a cylindrical sector extending through an arc greater than 180.degree.;
- a first retainer having a cylindrical body with a messenger wire receiving groove extending the length thereof and a handle projecting radially outwardly from said body, said first retainer being axially slidable into said first hook and rotatable therein between a first position in which said groove is aligned with the opening of said first hook and a second position in which said groove is within the confines of said seat of said first hook;
- and
- for each of said second hooks, a second retainer, each of said second retainers having a cylindrical body with at least one cable receiving groove extending the length thereof and a lever arm projecting radially outwardly from said body, each said second retainer being axially slidable into a said second hook and rotatable therein between a first position in which said groove of said second retainer is aligned with the opening of said second hook and a second position in which said groove of said second retainer is within the confines of said seat of said second hook, said groove of said second retainer being of such width as to permit lateral insertion of a cable therein when said second retainer is in said first position.
In a cable spacer for holding power transmission cables in spaced relation to one another and having a spacer body including a plurality of cable engaging hooks, the improvement in means for retaining the cables in said hooks characterized in that:
- each cable engaging hook includes a seat in the form of a cylindrical sector extending through an arc of greater than 180.degree.;
- and
- each said retainer means comprises a cylindrical body axially slidable into a said seat and rotatable therein, said body having at least one cable receiving groove extending the length thereof, and a lever arm projecting radially outwardly from said cylindrical body for rotating said retainer between a first position in which said groove is aligned with the opening of a said hook and a second position in which said groove is within the confines of said seat, said lever arm in said second position cooperating with said hook to hold said retainer in place in said seat, said groove being of such width as to permit lateral insertion of a cable therein when said retainer is in said first position.
