Abstract

A synthetic cross arm is provided for use in structural support of conductors on utility poles in an electrical grid. The synthetic cross arm consists of a flexible housing and a cable positioned within a chamber of the flexible housing. The cable is configured to prevent pieces of the synthetic cross arm from separating, falling, or pulling down or breaking utility lines or adjacent cross arms upon a break to the synthetic cross arm. A collar is provided for connecting two cross arms in a horizontal position on a vertical utility pole. A cross arm assembly is provided that includes a collar and first and second cross arms connected thereto. The cross arm assembly is configured so that the first and second cross arms may flex, deform, and rebound, thus reducing or preventing damage to the cross arm assembly.

Claims6

Dependent claims

A collar for connecting a cross arm to a utility pole, the collar comprising:

a first member having a top end, a bottom end, and first and second sides extending between the top and bottom ends defining a plane, the plane having an outer surface and an inner surface;
a first and second flange, the first flange connected to the first side of the first member and the second flange connected to the second side of the first member;
a first sleeve having a first end, a second end, a top, a bottom, and a front and back defining a chamber therein, the second end of the first sleeve connected to the outer surface of the plane of the first member, the second end of the first sleeve including an opening for receiving a portion of a cross arm into the chamber of the first sleeve;
a second member having a top end, a bottom end, and first and second sides extending between the top and bottom ends defining a plane, the plane having an outer surface and an inner surface;
a third and fourth flange, the third flange connected to the first side of the second member and the fourth flange connected to the second side of the second member, the third and fourth flange detachably connected to the first and second flange of the first member;
and
a second sleeve having a first end, a second end, a top, a bottom, and a front and back defining a chamber therein, the first end of the second sleeve connected to the outer surface of the plane of the second member, the second end of the second sleeve including an opening for receiving a portion of a cross arm into the chamber of the second sleeve.
