Abstract
The utility model discloses a marine signal cable. The marine signal cable adopts the structure that two or three insulated cores are sequentially wrapped by a polyester belt and an aluminum-plastic composite belt to form a single cable core after being pair-twisted, a plurality of single cable cores are twisted to form a cable core, a water-resisting filled layer is arranged in the clearance of the cable core, a double-sided water-resisting belt, a longitudinally wrapped aluminium belt and a halogen-free low-smoke flame-retardant polyolefin outer sheath layer are sequentially arranged outside the water-resisting filled layer and the cable core, and a copper wire is arranged on the inner layer of the aluminum-plastic composite belt. The cable provided by the utility model is very suitable for signal transmission in circuits of collective and distributive systems, control systems and the like on the occasions demanding much on explosion protection and water resistance.
Description
Technical field:
The utility model relates to a kind of cable, and specifically a kind of signal cable peculiar to vessel belongs to technical field of electric wires and cables.
Background technology:
Signal cable peculiar to vessel in use is laid in open deck, bathroom, freight house, refrigerated compartment, cabin and has places such as water accumulation steam or harmful steam.Do not have waterproof or moistureproof function for common signal cable peculiar to vessel, cable will absorb moisture in long-term use, cause decreasing insulating, thereby reduces the useful life of cable.In addition higher explosion hazard place is being arranged, also very high to the requirement of explosion proof of transmission signals cable, and the cable of ordinary construction can't satisfy the instructions for use of above-mentioned two kinds of occasions.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of signal cable peculiar to vessel, has favorable waterproof property, shielding properties, anti-external interference and line to interference little, have low electric capacity and low inductance.Be very suitable for transmission signals in the circuit such as the distributing system of requirement of explosion proof and waterproof requirement occasion and control system.
The utility model technical solution problem adopts following technical scheme:
Signal cable peculiar to vessel, adopt two or three thoroughly do away with wrapped successively polyester belt behind the edge core pair twists, aluminium-plastic tape constitutes single cable core, the many stranded formation cable conductors of cable core, be provided with the packed layer that blocks water in described cable conductor gap, described block water packed layer and cable conductor are disposed with two-sided waterstop, vertical alclad band and halogen-free and low-smoke flame-retardant polyolefin external sheath layer outward; Internal layer at described aluminium-plastic tape is provided with a copper wire as drainage thread.
Described insulated wire cores adopts solid conductor, is extruded with the flame-proof polyethylene insulating barrier at the skin of described conductor.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model adopts at cable core outside vertical bag one deck aluminium strip, can improve cable waterproof performance and shielding properties as screen again as watertight composition.
2, the utility model adopts the block water gasket for packing and the band that blocks water, and improves the water resistance of cable.
When 3, key of the present utility model is to improve the cable electrical property, should keep favorable waterproof property comprehensively, make it to have superior shield type performance again, external interference and line to interference little, have low electric capacity and a low inductance.Be very suitable for transmission signals in the circuit such as the distributing system of requirement of explosion proof and waterproof requirement occasion and control system.
Description of drawings:
Fig. 1 is the structural representation of the utility model cable.
Number in the figure: 1 conductor, 2 insulating barriers, 3 polyester belts, 4 aluminium-plastic tapes, 5 drainage threads, 6 packed layers that block water, 7 two-sided waterstops, 8 vertical alclad bands, 9 external sheath layers.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, the signal cable peculiar to vessel of present embodiment, adopt solid conductor 1, skin at described conductor 1 extrudes flame-proof polyethylene insulating barrier 2 formation insulated wire cores, two or three are thoroughly done away with wrapped successively polyester belt 3 behind the edge core pair twists, aluminium-plastic tape 4 constitutes single cable core, below aluminium-plastic tape 4, place a copper wire simultaneously as drainage thread 5, many cable cores are twisted into cable conductor, be provided with the packed layer 6 that blocks water in described cable conductor gap, described packed layer 6 and the cable conductor of blocking water is disposed with two-sided waterstop 7 outward, vertical alclad band 8 and halogen-free and low-smoke flame-retardant polyolefin external sheath layer 9.
Claims (2)
1. signal cable peculiar to vessel, it is characterized in that adopting two or three thoroughly do away with wrapped successively polyester belt (3) behind the edge core pair twists, aluminium-plastic tape (4) constitutes single cable core, the many stranded formation cable conductors of cable core, be provided with the packed layer that blocks water (6) in described cable conductor gap, described packed layer that blocks water (6) and cable conductor are disposed with two-sided waterstop (7), vertical alclad band (8) and halogen-free and low-smoke flame-retardant polyolefin external sheath layer (9) outward; Internal layer at described aluminium-plastic tape (3) is provided with a copper wire as drainage thread (5).
