Strict fire safety regulations apply to the interior of business and control areas. In 1974, the Convention for the Safety of Life at Sea was ratified by member countries and entered into force, and major revisions were made to fire protection structures.As a result, regulations regarding disaster prevention for marine electrical cable penetrations that are inseparable from fire protection structures have been significantly strengthened. Ta.

裏面に漏水しない水準にあることも要求される。 Conventionally, only waterproofing measures were taken as a main target, and a flame-resistant sealing material that does not harden at room temperature, such as Danseal P (manufactured by Furukawa Electric Co., Ltd., trade name), was used as a fireproof sealing material between electric wires and combing them. It is filled in between to form a fire spread prevention layer. However, particularly in the case of multi-stranded electric wires, filling with such flame-resistant sealing material requires a great deal of time and effort, which poses problems in workability. On the other hand, if the flame-resistant sealing material is insufficiently filled, it is extremely difficult to guarantee the A-60 grade, for example. Furthermore, depending on the ship class, in addition to such airtightness, a so-called hose test that takes watertightness into consideration is also required, that is, a level that does not leak water to the back surface when water is discharged at a hose nozzle pressure of 2.11 kg/cm 2 .

る。(i) The sealing work for fire prevention and waterproofing described above is difficult to perform; (ii) the sealing material has problems with mechanical strength; (iii) the electrical wire penetrations have a high standard. Fireproofing and waterproofing, specifically fireproofing performance, is in accordance with the A-60 class regulations.
It is difficult to obtain a waterproof performance that can withstand each of the provisions of the hose test mentioned above, so the inventors have made extensive studies to solve this problem, and as a result, they have created a pair of hoses divided in half along the axial direction, which will be described later. The present invention was achieved by discovering that it is possible to provide a fire protection and waterproofing device for a compartment penetration part of a marine electric wire that can solve the above problem by including a structure using a shielding layer cover having a cover member of the above.
