Embodiment 1）

[0020] See figure 1 , The high temperature resistant cable of this embodiment includes a main core 1 , a wrapping layer 2 , a shielding layer 3 , a second wrapping layer 4 and a sheath 5 .

[0021] See figure 1 , There are two main cores 1, the two main cores 1 have the same structure, and the two main cores 1 are provided with conductors 11 and insulating layers 12 in turn along their respective radial directions from inside to outside. The two main cores 1 are twisted into cables.

[0022] See figure 1 , the conductor 11 is made of a number of metal-plated copper wires with the same monofilament diameter twisted in the same direction, and the adjacent layers are twisted in reverse. This embodiment uses 19 tinned copper wires with a nominal diameter of 0.16 mm in the same direction. Twisted, adjacent layers twisted in reverse, the outermost layer is left.

[0023] See figure 1 , The insulating layer 12 is made of polyether ether ketone. The insulating layer 12 is extrude...

Abstract

The invention discloses a high-temperature resistant cable. The high-temperature resistant cable comprises two main line cores, a wrapping layer, a shielding layer, a second wrapping layer and a sheath, wherein the structures of the two main line cores 1 are same, the two main line cores respectively is provided with a conductor and an insulation layer sequentially from inside to outside along respective radial direction of the main line cores, the two main line cores are twisted to form the cable, the conductor is formed by bunching a plurality of metal-plated copper wires of which single wires are same in diameter in the same direction, adjacent layers are twisted in opposite directions, the insulation layer is made of polyetheretherketone and is arranged outside the conductor in an extruded manner, the wrapping layer is formed by wrapping a mica tape outside the two main line cores which are twisted, the shielding layer is formed by weaving a nickel-plated copper wire with a diameter being 0.1-0.3 millimeter outside the wrapping layer, the second wrapping layer is formed by wrapping the mica tape outside the shielding layer, the sheath is made of a stainless steel band material, and a stainless steel band is armored outside the second wrapping layer in an interlocking way.

Description

technical field [0001] The invention relates to a cable for ships, in particular to a high temperature resistant cable for ships. Background technique [0002] At present, the cables on board basically use low-smoke and halogen-free materials such as flame-retardant polyolefin and ethylene-propylene rubber, but the temperature resistance level of these materials is not high. ℃ high temperature and alternating temperature environment requirements. [0003] At present, high-temperature-resistant special cables in the dock cabin mainly use fluorine plastic insulated high-temperature cables. However, due to the fluorine element contained in fluoroplastics, fluorine releases toxic HF gas when burned, which belongs to the category of highly toxic substances. The toxicity of fluoroplastic cables after burning is 1.5 times that of PVC cables and 5 times that of halogen-free cables. It endangers human life and peripheral equipment, and cannot meet higher non-toxic requirements. C...
