Abstract
The utility model discloses a twist-resistance heat radiation cable used for a marine engine. The cable comprises three copper-core flexible conductors. A steel strand braided layer is arranged outside each copper-core flexible conductor. A high density polyethylene insulating layer coats each steel strand braided layer to form an insulated wire core. Each high density polyethylene insulating layer and each steel strand braided layer form an integrated body after an extrusion molding of each high density polyethylene insulating layer. Three insulated wire cores are mutually twisted into a bundle to form a cable core. The cable core is subjected an extrusion molding in an anti-tear silicone rubber buffer layer. Orthohexagonal honeycomb holes are arranged in the anti-tear silicone rubber buffer layer. An aluminium wire woven shield and an anti-tear silicone rubber oversheath layer coat the anti-tear silicone rubber buffer layer in order. The twist-resistance heat radiation cable of the utility model has a novel design structure, by designing the steel strand braided layers, the anti-tear silicone rubber buffer layer, heat radiation wind grooves and the like, the twist resistance performance and the heat radiation performance of the marine engine are improved. When the twist-resistance heat radiation cable is used in a complex environment with high temperature, vibration and oil plants, the performance is stable, and the transmission performance is not affected.
Description
technical field:
The utility model relates to electric wire, relates in particular to a kind of marine engine warp resistance cable that dispels the heat.
background technology:
At marine engines, when various metered quantities increase, the number of cables of its use also has the trend of increase, and simultaneously in order to improve commercial transport weight, hull also requires lightweight, densification, therefore cable has been proposed the requirement in light weight and thin footpath.
Warp resistance performance and the heat dispersion of marine engines are poor all the time, and the complex environment of near high temperature engine, vibration, oil plant, makes the local fault that easily produces of system, often can not meet expection instructions for use the useful life of relevant cables.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of marine engine warp resistance cable that dispels the heat, reasonable in design, can improve warp resistance performance and the heat dispersion of marine engines, while use in the complex environment of high temperature, vibration, oil plant, stable performance, transmission performance is unaffected.
The technical solution of the utility model is as follows:
The warp resistance cable that dispels the heat for marine engine, comprise three copper core flexible conductors, it is characterized in that: every copper core flexible conductor in three described copper core flexible conductors is provided with steel strands-woven outward and knits layer, steel strand wire braiding layer is coated with high density polyethylene (HDPE) insulating barrier and forms insulated wire cores, high density polyethylene (HDPE) insulating barrier becomes one with steel strand wire braiding layer after extrusion moulding, three mutual stranded bunchys of insulated wire cores form cable core, cable core through extrusion moulding in tear-proof silastic cord breaker, in tear-proof silastic cord breaker, be provided with the honeycomb hole of orthohexagonal, tear-proof silastic cord breaker is coated with aluminium wire woven shield outward successively, tear-proof silicon rubber external sheath layer.
The warp resistance cable that dispels the heat for described marine engine, is characterized in that: the outer wall of described tear-proof silicon rubber external sheath layer is provided with spaced apart, spiral radiation air groove.
The utility model has the advantages that:
The utility model structural design novelty, weave the designs such as layer, tear-proof silastic cord breaker and radiation air groove by steel strand wire, can improve warp resistance performance and the heat dispersion of marine engines, while use in the complex environment of high temperature, vibration, oil plant, stable performance, transmission performance is unaffected.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
The warp resistance cable that dispels the heat for marine engine, comprise three copper core flexible conductors 1, every copper core flexible conductor in three copper core flexible conductors 1 is provided with steel strands-woven outward and knits layer 2, steel strand wire braiding layer 2 is coated with high density polyethylene (HDPE) insulating barrier 3 and forms insulated wire cores, high density polyethylene (HDPE) insulating barrier 3 becomes one with steel strand wire braiding layer 2 after extrusion moulding, three mutual stranded bunchys of insulated wire cores form cable core, cable core through extrusion moulding in tear-proof silastic cord breaker 4, in tear-proof silastic cord breaker 4, be provided with the honeycomb hole 5 of orthohexagonal, the outer aluminium wire woven shield 6 that is coated with successively of tear-proof silastic cord breaker 4, tear-proof silicon rubber external sheath layer 7.
The outer wall of tear-proof silicon rubber external sheath layer 7 is provided with spaced apart, spiral radiation air groove 8.
The utility model can improve warp resistance performance and the heat dispersion of marine engines, while use in the complex environment of high temperature, vibration, oil plant, and stable performance, transmission performance is unaffected.
