Low-smoke inflaming retarding marine cable without inner sleeve

Abstract

The invention discloses a low-smoke inflaming retarding marine cable without an inner sleeve. The low-smoke inflaming retarding marine cable without the inner sleeve is mainly composed of a crosslinked polyethylene insulation layer, a metal armored layer, a water-blocking tape braid layer, a glass fiber fire retardant layer, control illuminating line cores and conductors. The water-blocking tape braid layer is arranged in the metal armored layer in an extruding mode, and the metal armored layer is covered with the crosslinked polyethylene insulation layer. A polyvinyl chloride jacket is arranged outside the control illuminating line cores. A plurality of sensing fibers are evenly arranged between the glass fiber fire retardant layer and the water-blocking tape braid layer. The three conductors are concentrically arranged outside a filling layer. The two control illuminating line cores, the three conductors and the filling layer are arranged together through the glass fiber fire retardant layer in an extruding mode. The control illuminating line cores are symmetrically arranged on the two sides of the filling layer. The low-smoke inflaming retarding marine cable has the fire retarding and water preventing functions, has multiple functions, and solves the problems that a common cable is non-watertight, non-fireproof and single in function.

Description

technical field [0001] The invention relates to the field of cables, in particular to a low-smoke flame-retardant marine cable without inner sleeve. Background technique [0002] At present, the existing marine cables include six core conductors with insulation layers, and an outer sheath is provided outside each core conductor. However, the general six-core cable has the problem of relatively single function, poor fire resistance and water resistance, thus giving The use brings inconvenience and affects the performance of the product. In these fields, some cables with fire resistance, strong waterproof and multiple functions should be used to better guarantee the use and improve the safety of personnel and equipment. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a low-smoke flame-retardant marine cable without inner sleeve. [0004] The present invention is realized ...

[0002] At present, the existing marine cables include six core conductors with insulation layers, and an outer sheath is provided outside each core conductor. However, the general six-core cable has the problem of relatively single function, poor fire resistance and water resistance, thus giving The use brings inconvenience and affects the performance of the product. In these fields, some cables with fire resistance, strong waterproof and various functions should be used to better guarantee the use and improve the safety of personnel and equipment.
