A cable holder (10) attaches to a cable (1) with a plurality of cores (2). The cable holder (10) has a receiving body (11) with a plurality of receiving chambers (12). The chambers (12) extend in a cable longitudinal direction (L). An insertion opening (13) is formed at least on one side of the receiving chamber for inserting an end of a core (2). A fastening portion (14) is connected to the receiving chamber (12). The fastening portion (14) fastens the cable holder (10) to the outer sheath of the cable (1) by a fastening device (3) engaging around the cable (1).

An isolator fitting for an opening in a metallic rib of an aircraft wing. The isolator fitting has first isolator mountable to the rib to position a first isolator opening in alignment with the opening of the rib. A second isolator is mountable to the rib and has a nut housing segment defining a second isolator opening to be positioned in alignment with the opening of the rib. A conduit extends between a first end and a second end, and a nut is mountable about an outer surface of the conduit to abut against the first isolator and mount the conduit thereto. The conduit is positionable to extend through the opening of the rib and through the first and second isolator openings to position the nut within the nut housing segment of the second isolator such that the nut housing segment is positioned between the nut and the rib.

An electrical distribution line cover includes a sleeve defining an elongate cavity extending along the length of the sleeve that is sized to receive an electrical distribution line when the sleeve is installed on the electrical distribution line. The sleeve defines an elongate passage extending along the length of the sleeve and configured to permit passage of the electrical distribution line into the elongate cavity. A resilient clip extends around an exterior surface of the sleeve and biases the passage of the sleeve toward a closed position for inhibiting the passage of the distribution line out of the cavity of the sleeve after the sleeve is installed on the distribution line.

High voltage insulators are disclosed, along with related methods of manufacture and use. The disclosed high voltage insulators include a core strength member joined to one or more end fittings and secured with one or more elastomeric members. A plastic body surrounds the core strength member, the elastomeric member, and at least a portion of the end fitting. In particular, the plastic body is molded over the elastomeric member(s) and, upon cooling, the plastic body exerts a radial compressive force on the underlying elastomeric member(s) to seal the joint of the high voltage insulator and protect it from moisture, even throughout temperature fluctuations in the field.

An electrical bushing having an anti-rotation mounting flange for preventing rotation of a body element of the electrical bushing is provided. The electrical bushing includes a mounting flange, at least one locking element and a body element having a circumferential protrusion. At least one first recess is formed in the circumferential protrusion, and the at least one locking element is configured to engage with the at least one first recess and with the mounting flange for restricting relative rotation of the body element relative to the mounting flange about a longitudinal axis R. A further aspect provides an electrical transformer including at least one electrical bushing according to the above. A yet further aspect provides a method for mounting the electrical bushing according to the above.

A shield system for an electric power transmission tower includes a plurality of panels configured to be secured to a cross-arm structure of the tower in adjacent, end-to-end arrangement so as to overlie insulators supported by the tower and prevent excrement from birds nesting and/or congregating on the tower from contacting and accumulating on the insulators. Each panel has opposite ends and opposite lateral edges extending between the opposite ends. A plurality of spaced-apart apertures are formed in each panel adjacent each of the lateral edges and at least one of the ends, and each aperture is configured to receive a respective fastener therethrough for securing the panel to the cross-arm structure. Each panel has a shape that generally conforms to a shape of a portion of the cross-arm structure to which the panel is secured.
