  • Patent number: 11435540
    Abstract: A cable management system includes a cap that cooperates with a housing to enclose a connection between a first cable and a second cable. The cap defines a first port and a second port through which cables extend into the housing. A base is to be coupled to the cap. The base includes a first clamp that protrudes from a surface of the base and maintains an alignment of a portion of the first cable with the first port. The base also includes a base interlock portion. A first cable guide, separate from the base, is to be installed on the cap to maintain an alignment of a portion of the second cable. The first cable guide includes a second clamp, and a first cable guide interlock portion that cooperates with the base interlock portion to interfere with separation of the first cable guide from the base.

  • Patent number: 11428293
    Abstract: A clamp, and cable management system including the clamp, includes a bolster with a first clamping surface, and a keeper that is to be coupled to the bolster. The keeper is adjustable relative to the bolster to establish a first separation of the keeper from the first clamping surface of the bolster, and a second separation of the keeper from the first clamping surface of the bolster. The first separation is different from the second separation. The keeper includes a second clamping surface configured to cooperate with a first object having a first exterior dimension, and a third clamping surface, different from the second clamping surface, that is configured to cooperate with a second object having a second exterior dimension.

  • Patent number: 8507799
    Abstract: An apparatus is provided that electrically insulates an elongate body from a rigid member. The apparatus includes an insulating part and a helically shaped securing part. The insulating part contacts either the elongate body or the rigid member thereby electrically insulating the elongate body from the rigid member. The helically shaped securing part prevents the insulating part from moving. The helically shaped securing part includes a multiple continuous rods, whereby the multiple rods are individual rods or sets of rods where at least two of the continuous rods are adhered together with an adhesive to form a set.

  • Publication number: 20130061466
    Abstract: A damper assembly system that can provide for multiple frequency responses to control Aeolian vibration in EHV (Extra High Voltage) applications is disclosed. The damper assembly comprises an asymmetric design that enables two disparate frequency responses at either side of the clamp that attaches the damper to a suspended member or cable. Two additional frequency responses are enabled at an inlet point of each of the damper weights. The damper weights can have a rounded or egg-shape together with an inner cavity so as to control corona discharge in EHV applications. Additionally, the tuned weights can be of disparate mass as well as asymmetric distances from the clamp.
