An electrical fitting for securing PVC jacketed metal clad (PVC-MC) or Teck 90 electrical cable to an electrical box or panel in a liquid-tight and concrete-tight fit. The electrical fitting includes a tubular fitting body having a threaded inbound and outbound end, a gripper ring, one or more grommets, a bushing, a sealing ring, a locknut, and a gland nut. The grommet includes an outbound end with a tubular wall portion and an inbound end with a flange and an inner lip. The gripper ring includes a tubular base, one or more fingers extending from the base, and arcuate ends on the fingers. The fingers include a curvature which matches the curvature of the base. The fitting will accommodate a range of cable sizes and while providing a liquid-tight and concrete-tight connection and proper electrical grounding of the cables to an electrical box or panel.

The present disclosure is directed to examples of universal cable attachments for securing a cable in a secured position. The universal cable attachments utilize a pair of counter-rotating lobes or one lobe and a counter surface to clamp against the cable. The lobes are configured such that they can accept a variety of cable diameters, thus eliminating the need for the provision of multiple sizes of unique cable attachments in certain applications. The lobes are configured such that they provide little or no resistance to a cable being inserted in an insertion direction and such that they lock against the cable when the cable is pulled in the opposite direction. In one example, the lobes have eccentrically oriented tapered channels to accomplish the clamping function. In another example, the lobes include a plurality of differently sized plates to accomplish the clamping function.

A high pressure cable reinforcement sleeve is provided having two or more bracket elements that are capable of forming a sleeve for surrounding a cable joint, wherein each bracket element has an outer wall and at least one inner protruding wall element.

A cable clamp for holding a cable, preferably for an LED driver, including a clamp cover and a clamp gear which can be joined together, thereby defining an inner space for accommodating a portion of the cable, and a bracket placed inside the inner space and configured to apply a clamping force on the cable, wherein the bracket is adjustable in a direction perpendicular to the axial direction of the cable such that the bracket can take different positions in the joined state.

A process for producing a flexible vulcanized joint between two electric power cables includes the steps of: producing an exposed conductor joint between each end of the two cable ends to be joined; producing an inner semi-conducting layer thereby radially surrounding and covering the exposed conductor joint; winding an insulation tape including an organic peroxide around the inner semi-conducting layer thereby radially surrounding and covering the inner semi-conducting layer; curing the insulation tape to produce an insulation layer; and producing an outer semi-conducting layer thereby radially surrounding and covering the insulation layer. The step of winding the insulation tape around the inner semi-conductor layer is performed under an oxygen-free atmosphere. The present invention also provides a flexible vulcanized joint produced by this process, and an electric power cable including such a joint.

A dispenser apparatus (10) for dispensing curable liquid material into a space in a cable gland is disclosed. The apparatus comprises a housing (12) for separately storing of components of a curable liquid material and provided with a respective first outlet (14) for each component. A mixing chamber (16) mixes the components to cause curing of the curable liquid material and has an inlet (18) for receiving the components from the first outlets, and a second outlet (20) for the mixed components. A plunger (22) urges the components out of storage chambers of the housing via the first outlets and into the mixing chamber via the inlet. The dispenser apparatus is adapted to be located in a body of a cable gland such that the mixed components are dispensable from, the second outlet into a space defined by the body and a cable extending through the body.

A duplex electrical cable fitting includes a connector body having a mounting member and a base member, a cover having a cover hook, and a locknut configured to engage with the mounting member. The mounting member has a mounting member sidewall extending between first and second open ends with the first and second open ends defining a cable passage therebetween. The base member has a cover engaging member, which defines a cover engaging hole. The base member is connected to the mounting member at the second open end and extends downwardly therefrom. The cover hook is movably connected to the base member via the cover engaging hole so as to allow the cover to be movable relative thereto between open and closed positions.

A connection seat includes a base including a top plate and a pedestal connected to each other, a metal member including a body and at least one grounding end, a press cover including a protruding portion, and a flexible concatenation portion connecting the base and the press cover. The base further includes a first trench located on the top plate, a second trench located between the top plate and the pedestal, and a through-hole running through the top plate and the pedestal. A coaxial cable can extend into the base along the first trench, to be detachably mounted to the base. The body extends into the second trench to engage the metal member with the base, and the grounding end extends out of the pedestal. When the concatenation portion is bent such that the press cover covers the top plate, the protruding portion correspondingly protrudes toward the through-hole.

A cover assembly for covering an elongate substrate includes a resilient, elastically expandable sleeve member and a holdout device. The sleeve member defines an axially extending inner sleeve passage. The holdout device includes a generally tubular, flexible bladder sleeve mounted in the inner sleeve passage. The bladder sleeve defines a cavity and a holdout passage to receive the elongate substrate. The cavity is inflated or inflatable with an inflation gas.
