A utility or marine pole comprises a honeycomb core having an outer surface and a rubber coating on substantially all of the outer surface of the core. The core has a length of from about 12 feet to about 30 feet and a circumference of from about 5 inches to about 15 inches. A bracket for a pole used for supporting wires, the bracket comprising a body being circular in horizontal cross section, means for adjusting the diameter of the body, and a lateral extension having a first end portion supported by the body and an opposed second end portion, wherein the second end portion has an opening for receiving a wire. A railroad crossing section comprising a honeycomb core has a circumferential outer surface and being rectangular in vertical cross section and a rubber coating on substantially all of the outer surface of the core.

A system for fastening an elongated composite member to a column 2 extending through an opening in the elongated composite member 1. The elongated composite member 1 comprises an opening formed by a first aperture having a first peripheral edge and a second aperture having a second peripheral edge through the composite wall member. A stress distribution member 31 having a conical section 38 extends between the first and second apertures. The invention also relates to a stress distribution member 31 of a composite material having a frustum-shaped section and a pylon for power lines.

Freileitungseinrichtung mit einer Mehrzahl von Masten und mit zwischen den Masten verlaufenden und an den Masten fixierten Leiterseilen. Es ist ein zwischen den Masten verlaufendes und an den Masten fixiertes Stabilisierungsseil vorgesehen. Das Stabilisierungsseil ist oberhalb zumindest eines Teils der Leiterseile angeordnet. Zumindest ein Teil der Leiterseile ist in den Bereichen zwischen zwei Masten jeweils an zumindest einem Aufhängungspunkt an dem Stabilisierungsseil, den Durchhang der Leiterseile reduzierend, aufgehängt.

Freileitungseinrichtung, insbesondere für Hochspannungsfreileitungen, - mit einer Mehrzahl von Masten und mit zwischen den Masten verlaufenden und an den Masten fixierten Leiterseilen. Es sind zumindest zwei Drehstromsysteme mit jeweils drei Phasen vorhanden und jeder Phase ist ein Leiterseil zugeordnet. Die Leiterseile sind im Querschnitt in Form eines Polygons angeordnet. Die Leiterseile zumindest eines Drehstromsystems sind mit einer Phasenfolge im Rechtsdrehsinn angeordnet und die Leiterseile zumindest eines Drehstromsystems sind mit einer Phasenfolge im Linksdrehsinn angeordnet.
摘要:
The invention concerns a switching apparatus designed to be used with an electric power transmission line section comprising several phase lines. Each of the phase lines includes several conductors electrically insulated from one another and connected in parallel. The conductors of each phase line are mutually shorted out at two ends of the section. The apparatus comprises pairs of switches connected in parallel, for selectively opening and closing each phase line conductors, a sensing device for detecting the section current operating conditions, and a control device for controlling the switch pairs based on the section current operating conditions. The invention also concerns a switching method.

A tripping device for opening the contacts of a circuit breaker associated therewith following the detection of a residual current exceeding a preset limit by a detecting device, comprising an enclosure for containing and supporting a kinematic mechanism which has:
-- an actuation lever and a tripping lever, which are geometrically coupled to each other and are both pivoted on a first pivot of the enclosure, the actuation lever being operatively connected to an actuator which is actuated by the detecting device; -- an indicator lever, with which an actuation spring is associated, and a transmission lever, said indicator and transmission levers being mutually operatively coupled and being both pivoted on a second pivot of the enclosure, said transmission lever having a coupling pivot for coupling to the kinematic system of the associated circuit breaker; -- an engagement lever, which is geometrically coupled to the indicator lever and is detachably connected to the tripping lever.
