A hydrofoil system is disclosed, having a fuselage with a propeller mounted to one end of the fuselage and a wing extending laterally from the fuselage. The fuselage is configured for removable attachment to a mast, so that the mast when attached extends from the fuselage in a direction substantially orthogonal to the longitudinal axis and also substantially orthogonal to the wing. A tail wing is connected to the fuselage by a tail strut, so that the tail wing is positioned beyond the end of the fuselage to which the propeller is attached. A motor is housed in the fuselage and has a cable connected thereto, the cable extending outside the fuselage, wherein a removable sealing system inhibits water ingress to the motor at the location where the cable is connected when the sealing system is installed in the fuselage.

A seal for securing a cable to a fuse box includes a plastic body and a rubber insert. The plastic body has a receiving cavity along an inner surface. The rubber insert features an outside structure to join with the inner surface of the plastic body, an inside structure to surround the cable, and a fitting rib along an outside surface of the outside structure, the fitting rib to occupy the receiving cavity. The inside structure of the rubber insert moves in response to movement of the cable while the outside structure does not move.

A wire harness is provided with a cable including wires coated with a sheath, a rubber stopper that covers an end of the sheath together with a portion in a longitudinal direction of the wires, and a cover made of a harder material than the rubber stopper and accommodating the rubber stopper. The rubber stopper integrally has a sheath sealing portion having an inner peripheral surface that comes into contact with an outer peripheral surface of the sheath, and a wire sealing portion including plural insertion holes to which the wires are inserted. The cover integrally has a sheath holding portion that crimps and holds an uncovered portion of the sheath that is not covered by the rubber stopper, and a rubber stopper holding portion that crimps and holds the rubber stopper.

The invention relates to an electrical conductor for the conduction of electrical current through an opening of a housing wall, wherein the electrical conductor is enclosed, at least in a first sealing segment by a sealing body made from an elastic material. The electrical conductor can be inserted with the sealing body into an opening of a housing wall for sealing between sealing body and housing wall. The electrical conductor has a materially bonded connection to the sealing body, and a fastening part is provided on the conductor and has an axial through-opening through which the electrical conductor is inserted, wherein the fastening part extends radially, starting from the axial through-opening, in a first axial segment which has the maximum radial extension of the fastening part perpendicular to the axial through-opening. The fastening part has, on one side or two sides of the first axial segment, a second axial segment and/or a third axial segment respectively forming a radially circumferential separation region for a casting tool. The invention furthermore relates to a corresponding method for production.

Provided is an interface for connecting a cable arranged in a shell to a receiving structure, the interface including: a connector including a connection area for fixing the connector to a cable support of the receiving structure and a transmission area for receiving the cable and the shell, a lower seal, an upper seal, a chamber element configured to coat the cable between the lower seal and the upper seal. Also provided is a hang-off system and a method for connecting a cable arranged in a shell to a receiving structure.

A cable gland and methods for earthing, grounding, bonding, and electromagnetic capability with armored, metal-clad, and metallic-sheathed cable types. The cable gland comprises a gland body, a plurality of extensions, an elastomer seal, a compression member configured to rotate the plurality of extensions towards to the elastomer seal, and an earthing insert mounted in the gland body configured to electrically connect a cable to a neutral and/or grounded conductor. The cable gland is configured to provide an air-tight seal between the exterior of the cable and the elastomer seal through rotation of the plurality of extension upon the elastomer seal. The cable gland may include an o-ring and nut to secure the cable gland to a planar body. The earthing insert comprises a grounding spring in electrical communication with a metallic portion of the cable and a neutral and/or grounded conductor.
