An apparatus includes a strain relief formed in helical shape and formed with a U-shaped channel. The strain relief can be used around a cable of a component or a spool extension of a fiber tray.

A submarine power cable having: a power core including a conductor, wherein the conductor has a conductor joint in a joint region of the power core, a main armor layer including a plurality of main armor wires arranged around the power core and extending in the axial direction of the power core, and a joint reinforcement armor layer including a plurality of joint reinforcement armor wires axially locked relative to the main armor wires, wherein the joint reinforcement armor layer is provided only in the joint region and arranged layered with the main armor layer, the joint reinforcement armor layer and the main armor layer thereby forming a dual-layer armor only in the joint region.

The present disclosure relates to a submersible apparatus (1) for testing a submarine high voltage (HV) cable system. The apparatus (1) includes a cable termination (100) including an electrical insulator (101) and a shielding electrode (102) for the electrical connection with a cable end (201). The apparatus (1) additionally includes a cable bend restrictor (300) having a through channel (301), and a termination locking (400) in through communication with the cable bend restrictor (300) and the cable termination (100). According to another aspect, a method for testing a submarine high voltage (HV) cable apparatus using the above to testing apparatus (1) is additionally disclosed.

Embodiments of a tensile strength limiting system are provided. The tensile strength limiting system is configured to cause breakage of an optical fiber cable at a predetermined tensile loading below a tensile strength of the optical fiber cable. The tensile strength limiting system includes a force limiter configured for attachment to the optical fiber cable strung on an aerial pole and a restriction clip through which the optical fiber cable is configured to be looped. At the predetermined tensile loading, the force limiter is configured to allow the optical fiber cable to pull through the restriction clip; and the restriction clip is configured to force the optical fiber cable to bend below a minimum bend radius of a strength member within the optical fiber cable such that the strength member breaks.

A tension relief for supply lines and a block-like clamping part therefor, which has a lateral surface designed as a clamping surface. The clamping surface of the clamping part is formed at least in one clamping portion by an elastic wall, which is delimited on the side facing away from the clamping surface by a cavity structure, which is formed by additional walls. The clamping part can be variedly used without modification on certain line diameters, in particular in a tension relief of a cable carrier or also in a connector housing.

In some examples, a feedthrough assembly for a medical device may include a ferrule. The ferrule defines an aperture extending through the ferrule from an outer end surface defined by the ferrule to an end inner end surface defined by the ferrule. The aperture includes a first portion having a first diameter and a second portion having a second diameter less than the first diameter. The aperture defines a longitudinal axis extending therethrough and the ferrule defines a ledge between the first and second portions of the aperture that extends radially inward toward the longitudinal axis. The feedthrough assembly further may include a conductive pin within the aperture and an insulating member surrounding at least a portion of the pin. The insulating member may electrically insulate the conductive pin from the ferrule, and the ledge and a surface of the insulating member adjacent the ledge may define a space therebetween.

A tracking device for use in a surgical navigation system. The device includes an electromagnetic sensor configured to generate a sensor signal that depends on an external electromagnetic field. The device also includes at least one line element electrically connected to the sensor. The line element includes a first line section, a second line section, and a third line section arranged between the first and second line sections. A strain relieve unit includes a core, an outer surface, and at least one recess which extends in the outer surface circumferentially around a longitudinal axis of the core. The first line section extends into the strain relieve unit on a first side of the strain relieve unit, the second line section extends into the strain relieve unit on a second side of the strain relieve unit opposite the first side, and the third line section extends within the recess.

The present disclosure relates to a re-enterable enclosure for a fiber optic network. The enclosure can include features such as a low compression-force perimeter gasket, cable seals constructed to seal effectively seal triple points, multi-function port size reducer plugs and multi-function blind plugs.
