Technical Field

The utility model relates to a field of cable especially relates to the structure of connecting communication, instrument and electronic equipment's cable on naval vessel.

Background

With the development of economic globalization, the importance of oceans is increasingly prominent, and the importance of various countries on ocean safety is continuously increased, which leads to the increase of the market demand of ships. In order to ensure the ocean benefits and the national safety of China, the country also increases the investment on the construction of naval teams, the manufacturing of ships on water and under water is gradually increased, particularly, the integral weight reduction of a ship body is implemented for the requirement of the navigation speed of some novel ships, so that the rapid development of various light-weight instruments and equipment is driven, the demand is also rapidly increased at the same time, a high-performance light communication cable and an instrument cable are required to be matched with a motor for use, the field work requirement is met, and the cable is an important task of cable scientific research and production enterprises. The common cable has low temperature resistance level, small carrying capacity, low temperature and humidity resistance and poor flame retardance, and can release a large amount of toxic gas and dense smoke during combustion to harm the health of people; the existing local area network cable solves the problems of large digital signal attenuation, unstable transmission quality and weak electromagnetic interference resistance of a common communication cable, but has large volume, heavy weight, poor mechanical strength and tensile strength and can not meet the requirements of ships.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming prior art's not enough, provide a naval vessel with there being not steamed low fire-retardant light-duty communication of toxicity, instrument and electronic equipment cable of cigarette lowly, under the no halogen nature and the mechanical characteristic that keep the cable, reduced the whole volume of cable and reduceed cable weight, more be suitable for and use on the naval vessel.

The purpose of the utility model is realized like this: the cable comprises a wire core consisting of a tinned copper conductor, an irradiation crosslinking halogen-free polyolefin insulating layer and a tinned copper wire braided split-phase shielding layer, wherein the irradiation crosslinking halogen-free polyolefin insulating layer is arranged outside the tinned copper conductor, and the tinned copper wire braided split-phase shielding layer is arranged outside the irradiation crosslinking halogen-free polyolefin insulating layer; the cable core has three and transposition mutually, is equipped with around the covering on three sinle silks after the transposition, is formed by halogen-free area and polyester tape combination around the covering, is equipped with tinned copper wire and weaves the armor outside around the covering, is equipped with 105 degrees army standard resistant oily halogen-free flame retardant irradiation sheath outside tinned copper wire weaves the armor.

Preferably, a foamed polyethylene tape filling layer is arranged between the wrapping layer and the three wire cores.

Preferably, the halogen-free tape of the wrapping layer is arranged on the inner side of the polyester tape.

Preferably, the halogen-free tape of the wrapping layer is arranged on the outer side of the polyester tape.

The utility model has the advantages that: the halogen-free cable is characterized in that a halogen-free tape and polyester tape two-layer combined co-winding mode is adopted, and the foamed polyethylene tape is filled, so that the whole volume of the cable is reduced, the weight of the cable body is reduced under the condition of keeping the halogen-free property and the mechanical property of the cable, and the cable is more suitable for being used on naval vessels. The product has compact structure, simple manufacturing process and extremely convenient installation, use and maintenance.

Detailed Description

Example 1

As shown in fig. 1, the cable for the first ship, low-smoke low-toxicity flame-retardant light communication, instrument and electronic equipment cable, comprises a wire core 8 consisting of a tin-plated copper conductor 1, an irradiation crosslinking halogen-free polyolefin insulating layer 2 and a tin-plated copper wire braided split-phase shielding layer 3, wherein the irradiation crosslinking halogen-free polyolefin insulating layer 2 is extruded outside the tin-plated copper conductor 1, and the tin-plated copper wire braided split-phase shielding layer 3 is arranged outside the irradiation crosslinking halogen-free polyolefin insulating layer 2.

The cable core 8 has three, and three cable cores 8 are twisted with the foamed polyethylene tape filling layer 7. The package 4 is formed by the combination of no halogen area 41 and polyester area 42, and no halogen area 41 sets up in the inboard of polyester area 42, and no halogen area 41 and polyester area 42 are around outside three sinle silks 8 and the foamed polyethylene area filling layer 7 after the transposition, are equipped with the tinned copper wire outside package 4 and weave armor 5, weave armor 5 at the tinned copper wire and be equipped with 105 degrees army's standard resistant oily halogen-free fire-retardant radiation sheath 6 outward.

The three wire cores 8 of the utility model are provided with the irradiation crosslinking halogen-free polyolefin insulating layer 2 and the tinned copper wire braided split-phase shielding layer 3, so that the insulating effect and the shielding effect are good; the halogen-free tape 41 and the polyester tape 42 are combined and co-wound in two layers, and the foamed polyethylene tape filling layer 7 is adopted, so that the whole volume of the cable is reduced and the weight of the cable body is reduced under the condition of keeping the halogen-free property and the mechanical property of the cable. The 105-DEG military-standard oil-resistant halogen-free flame-retardant irradiation sheath 6 has oil-resistant and flame-retardant properties, and avoids generating smoke and toxic gas; the combination of the tinned copper wire braided armor layer 5 and the 105-degree army-standard oil-resistant halogen-free flame-retardant irradiation sheath 6 greatly improves the mechanical property and the tensile strength, and avoids cracking in the use process.
