  • Patent number: 11237026
    Abstract: Disclosed is an inspection system for a cable, pipe or wire transit having a plurality of transit elements in a sealed installation of cables, pipes or wires at a site. A portable inspection device has a controller and an RFID interface. The transit has an RFID chip with a first memory area which stores an identity of the transit, and a second memory area. The controller reads the identity of the transit via the RFID interface, records detailed operational integrity status data of the transit elements, obtains a status indication representing an assessed overall operational integrity status of the transit based on the recorded detailed operational integrity status data, transmits the obtained status indication via the RFID interface to the transit for storage in the second memory area of the RFID chip, and makes the recorded detailed operational integrity status data or the obtained status indication available to a maintenance server together with the read transit identity.

  • Patent number: 9765908
    Abstract: A seal, lead-through or transit for cables, wires or pipes which seal, lead-through or transit has one or more compressible parts surrounding the cable, etc. and a position of an opening receiving the cable, etc. is adjustable. In one example, the opening may be placed off-center on a partition line between two module parts. In other example, an inner compressible body may be placed inside an outer compressible body or between two module parts. The inner compressible body has an opening receiving the cable, etc. which opening is placed off-center. By rotating the inner compressible body the position of the opening receiving a cable, etc. is adjusted.

  • Publication number: 20120032036
    Abstract: Blocks of a cable, wire or pipe transition that may be placed together to form a structure of a number of the blocks. Each block has a generally rectangular shape and forms a part of the cable, wire or pipe transition together with at least one further block. Each block has at least one recess placed in the middle of the block. Inside the recess a number of peelable sheets are received. The sheets may be peeled off to adapt the inner diameter of the block to the outer diameter of a cable, wire or pipe to be received in the recess. Each block has elements for fastening further blocks to the block above or below the block.

  • Publication number: 20120018961
    Abstract: A seal, lead-through or transit for cables, wires or pipes comprises a base part having a groove for receiving the cable etc. and in which groove a number of peelable sheets is received. The seal etc. may be designed to automatically give low friction and enhanced sealing between a cable etc. and the sheets and between the base parts at installation.

  • Publication number: 20120018959
    Abstract: A seal, lead-through or transit for cables, wires or pipes which seal, lead-through or transit has one or more compressible parts surrounding the cable, etc. and a position of an opening receiving the cable, etc. is adjustable. In one example, the opening may be placed off-centre on a partition line between two module parts. In other example, an inner compressible body may be placed inside an outer compressible body or between two module parts The inner compressible body has an opening receiving the cable, etc. which opening is placed off-centre. By rotating the inner compressible body the position of the opening receiving a cable, etc. is adjusted.

  • Publication number: 20120018960
    Abstract: A sealing system for cable entries or pipe penetrations including a frame receiving one or more compressible modules surrounding a cable or pipe, whereby a barrier is formed of the one or more modules and at least one compression unit in the frame. The compressible module may have at least one opening provided with at least one peelable layer for adapting to the diameter of a cable or pipe, which at least one peelable layer is placed in a profile. Each compressible module may include a movement preventing device that engages the frame and/or an adjacent compressible module in an axial direction, so as to obstruct movement in an axial direction.
