  • Publication number: 20100155991
    Abstract: A bushing can include a shoulder, a ring, and a ground shield. The ring can be arranged circumferentially around a first outside diameter of the bushing, wherein the ring includes a channel. The ground shield can include a semiconductive rubber collar that forms part of an outer surface of the bushing and extends circumferentially under a portion of the ring. The insulative portion can be adjacent to the ring and disposed over a portion of the ground shield. A method of manufacturing the bushing can include placing the ring and the ground shield into a mold, the ground shield including holes therein, and injecting insulative material into the mold to create an insulative layer within a cavity formed by the ring and the ground shield, the holes in the ground shield allowing some of the insulating material to flow therethrough to create the insulative portion adjacent the ring.

  • Patent number: 7708576
    Abstract: A high-voltage electrical connector system comprises a bushing with a longitudinal axis, a shoulder, a first end, and a second end, wherein the shoulder is between the first end and the second end; a ring arranged circumferentially around a first outside diameter of the bushing, the ring disposed between the shoulder and the second end, the ring including a channel therein defining a circumferential extension extending axially toward the first end; a ground shield disposed on a second outside diameter of the bushing between the ring and the second end, the ground shield comprising one or more of conductive material and semiconductive material; and an insulative portion adjacent the ring and disposed circumferentially over a portion of the ground shield.

  • Publication number: 20020168887
    Abstract: Apparatus for reducing the risk of flashover during loadbreak operations of insulated separable connectors. A substantial airtight seal is prevented between the collar of the bushing insert and the cuff of the mating component. The connection is vented to break any adhesion between the bushing insert and the mating component cuff and to provide a chamfered airway for atmospheric airflow during removal of the mating component. A latch ring is reformed to include at least one raised edge about its outer diameter. Each raised edge has the shape of a sharply angled ramp and extends outward. There may be four or six raised edges.
