  • Publication number: 20230063718
    Abstract: A cable includes a pair of conductors extending longitudinally and spaced apart from each other, an inner insulating layer circumferentially extending around an outside of the conductors and fixing the conductors, a conductive shielding layer circumferentially extending around an outside of the inner insulating layer, and an insulating sheath extending around an outer peripheral surface of the conductive shielding layer. The insulating sheath is at least one of an extruded layer and a heat shrinkable sleeve.

  • Patent number: 8800676
    Abstract: The present invention relates to a novel hand-held aerosol fire suppression apparatus, comprising thermal insulating layer (3), inner cylinder (4), aerosol generating agent (5), heat insulating material (6), jet nozzle (9), tapered jet orifice (10), enclosure (11), ignition head (12) and piezoelectric crystal assembly (13), wherein the thermal insulating layer (3) is arranged between the inner cylinder (4) and the aerosol generating agent (5), and the jet nozzle (9) is screwed to the enclosure (11) by means of a thread structure that comprises 3˜6 thread segments. Compared to that in the prior art, with the segment thread design for screwing the jet nozzle to the enclosure, the time required for removing the jet nozzle can be reduced significantly, and therefore the apparatus in the present invention has much better safety feature against accidents.
