Abstract: The present disclosure provides for an electrical utility temporary crossarm for quick connection to a crossarm of a utility pole. An end cap retention member is removably connected to a proximal end of an elongated crossarm of the electrical utility temporary crossarm and has an annular wall that includes one or more locking ribs arranged longitudinally and extending radially outwardly. A horn cap and a horn base is provided where each has a concave portion which defines a longitudinal support channel configured to receive the locking ribs in lock and key style arrangement. A wire holding member disposed on the distal end of the elongated crossarm member for receiving and securing an electrical wire.

Abstract: A gain plate is made of reinforced plastic for attaching to a pole and a cross arm and includes a pole channel and a cross arm channel. The pole channel has a front plate, two side plates, and two end plates that that form a rear-facing cavity. There are a plurality of cross members disposed in the rear-facing cavity and at least some of the plurality of cross members having radiused surface. The cross arm channel is disposed perpendicularly to the pole channel, the cross arm channel configured to received therein a cross arm.

Abstract: An overhead power distribution line (10) comprises a tension resistant pole (101), two composite crossbeams (102) and tension resistant fixing members (103). A middle portion of the composite crossbeam (102) is horizontally secured on the tension resistant pole (101), and end portions of the composite crossbeam (102) are connected to the tension resistant fixing members (103). The tension resistant fixing members (103) enable the two composite crossbeams (102) to integrally connect and are for fixing conducting lines. With the above configuration, two composite crossbeams (102) are secured on the same horizontal plane of the tension resistant pole (101), thus satisfying vertical tension of a tension resistant requirement. Further, by using composited crossbeam bodies (102), a dry arc distance is significantly increased, and electrical lightning resistance performance is enhanced, preventing incidents such as line disconnection and flashover caused by lightning strike. The composite crossbeams (102) are maintenance-free and do not require periodical inspection and maintenance, significantly reducing labor costs. The use of crossbeams (102) can further eliminate the use of tension insulators and simplify the structure of lines.

Abstract: A support system for supporting power distribution or transmission lines includes a support pole having a first end and a second and a crossarm attached to the support pole, proximate the first end of the support pole. The crossarm has a first end, a second end and one or more side walls extending between the first and second ends of the crossarm. The side walls of the crossarm define an elongated interior space. The support system further includes an internal conduit formed in the interior space of the crossarm. The internal conduit extends along an axial direction of the crossarm. The internal conduit is made from insulative material.

Abstract: Provided is a cross arm with one end connected to a tower body and a free end for connecting a conducting wire. Free end comprises an end connecting piece and an extension piece. Extension piece is fixed with end connecting piece. Extension piece protrudes horizontally from end connecting piece. Conducting wire is connected to extension piece. An angle between extension piece and a cross arm center line is greater than that between conducting wire and cross arm center line. Cross arm free end includes a jumper wire device horizontally arranged on end connecting piece for hitching jumper wire. Extension piece use increases distance between conducting wire and tower body when turning angle condition is met. Gap requirement between conducting wire and tower body is met, and cross arm length increase is eliminated. Horizontally arranging jumper wire device on end connecting piece reduces distance between wire layers and tower body size.
