Abstract: The present disclosure is directed to a method of producing a surge arrestor module, comprising the acts of (i) providing a plurality of MOV blocks arranged in a stack, (ii) applying an epoxy-reinforced structural layer to an outer surface of the stack, (iii) after the applying, inserting the stack into a flexible bladder, and (iv) curing the epoxy-reinforced structural layer with elevated temperatures while the flexible bladder applies radially aligned pressure to the stack and a tool applies axially aligned pressure to the stack. The present disclosure also includes an apparatus for performing the methods described herein. The apparatus includes an outer case structure and a flexible bladder that fits within the outer case structure. A hollow inner region of the outer case structure is pressurized to force the flexible bladder against the surge arrestor module as the surge arrestor module is curing.

Abstract: An elbow connector receives a cable assembly having a lug with a lug aperture. The elbow connector comprises a receiving cavity for the lug of the cable assembly and a fastener assembly. The fastener assembly has a connecting rod, a fastener tube, and a fastener. The fastener is configured for movement within the fastener tube. The connecting rod has a bumper for engaging the lug and an obstruction element for engaging the fastener. The connecting rod is moveable between (i) a blocking position in which the obstruction element indicates the fastener is unaligned with the lug aperture, and (ii) a non-blocking position in which the fastener is free of the obstruction element and aligned with the lug aperture. The connecting rod transitions to the non-blocking position in response to the lug moving the bumper to a point where the fastener and the lug aperture are aligned.

Abstract: An elbow connector receives a cable assembly having a lug with a lug aperture. The elbow connector includes a receiving cavity for the lug and a fastener assembly. The fastener assembly has a latch, a spring, and a fastener. The fastener moves toward the lug. The latch has a bumper for engaging the lug and an obstruction element for engaging the fastener. The latch pivots between (i) a blocking position in which the obstruction element inhibits a certain movement of the fastener, and (ii) a non-blocking position in which the obstruction element is free of the fastener allowing the fastener to be fastened to the lug via the lug aperture. The latch is biased toward the blocking position by the spring and transitions to the non-blocking position in response to the lug moving the bumper to a position at which the lug aperture is aligned with the fastener.

Abstract: A fitting for injecting a first fluid into an injection port of a cable accessory. The fitting includes at least one seal positioned on an injection nozzle. The nozzle is configured to be inserted into the port and has an internal fluid passageway through which the first fluid is injected into the accessory. The seal forms at least one fluid tight seal between the nozzle and the port. The fluid tight seal prevents the first fluid from exiting the accessory and flowing into an outer portion of the port and prevents a second fluid from flowing into an inner portion of the port. The first and second fluids have first and second voltage potentials, respectively. The second voltage potential is different from the first voltage potential. The seal isolates the first and second voltage potentials by isolating the first fluid from the second fluid.

Abstract: An insert for constructing a cable accessory used to inject a fluid into a cable. The cable accessory has an outer body defining an interior configured to house a conductor of the cable. The outer body includes an injection port with an internal channel configured to receive the fluid. The insert has first and second portions. The first portion is configured to line a portion of the interior of the cable accessory. The first portion has a first through-channel configured to allow the conductor of the cable to pass at least partway therethrough. The second portion is configured to line the internal channel of the injection port. The second portion has a second through-channel in fluid communication with the first through-channel. The insert is less permeable to the fluid than the outer body of the cable accessory. The insert may be molded into the outer body.

Abstract: An elbow arrester with a T-body is disclosed capable of coupling with an apparatus for protection from transient over voltage, and coupling with additional cable accessories, without having to loosen the initial connection with the coupled apparatus. The elbow body of the T-body arrester has a first portion, and a second portion protruding from an intermediate section of the first portion to define a T-body. A receiving feature is located within the first portion extending towards a first end, while a male feature is coupled to a second end of the first portion, opposite from the receiving feature. A coupling fastener is integrally molded into the first portion, providing for an apparatus coupled to the coupling fastener to be decoupled without loosening the connection of another apparatus connected to the T-Body elbow. Further, decoupling the other apparatus does not loosen the apparatus coupled to the coupling fastener.

Abstract: A self-supported jacket seal designed for a cable connector so that after a cable is inserted into the cable connector, the integrated jacket seal protects any exposed portion of the cable without requiring any additional installation steps. The self-supported feature is provided by a plurality of rigid ridges positioned on the outer surface of the jacket seal. The ridges strengthen the construction of the component so that the jacket seal substantially maintains its shape when a cable is slidably inserted therewithin. Because the seal does not buckle when installed, it does not require any additional installation steps as found in other similar inventions known in the art.
