Heat-conducting type degaussing cable for ship

Abstract

The invention discloses a heat-conducting type degaussing cable for a ship. The heat-conducting type degaussing cable comprises a copper conductor located at the center, the outer surface of the copper conductor is coated with a heat-conducting type ethylene propylene rubber insulating layer, and the outer surface of the heat-conducting type ethylene propylene rubber insulating layer is coated with a chlorosulfonated polyethylene rubber sheath layer. The heat-conducting type ethylene propylene rubber insulating layer is prepared from the following component in parts by weight: ethylene-propylene-diene monomer Kep210, talc powder, insulating clay, micron boron nitride, nano aluminum nitride, paraffin oil 2280, white carbon black, zinc oxide, microcrystalline wax, titanium dioxide, an anti-aging agent RD, an anti-aging synergist MB, DCP, TAC, a coupling agent KH-550, 1801 stearic acid and an adhesive XH-3. The heat-conducting type degaussing cable solves the problem that a ship degaussing cable needs the characteristics such as salt fog resistance, ultraviolet light resistance, high load flow and high wear resistance; and the bonding strength of the heat-conducting type ethylene propylene rubber insulating layer and the chlorosulfonated polyethylene rubber sheath layer is improved, and the layering phenomenon caused when the ship degaussing cable is used in occasions such as winding, dragging, long-term contact with salt mist or immersion in sea water is avoided.

Description

technical field [0001] The invention relates to a cable for ships, in particular to a heat-conducting degaussing cable for ships. Background technique [0002] At present, most domestic single-core degaussing cables are insulated with conventional ethylene-propylene rubber or cross-linked polyethylene, and the sheath is made of conventional chlorosulfonated polyethylene rubber or polyurethane materials, which cannot effectively conduct heat inside the cable and have a short service life. The degaussing cable supporting the vehicle degaussing equipment is produced with silicone rubber insulation and sheath. Although the high temperature resistance of silicone rubber can effectively increase the current carrying capacity of the cable, the internal heat cannot be conducted and the strength and wear resistance of the silicone rubber material are average. Poor, easy to wear and scrap during long-term drag use. In addition, polyurethane sheath materials are also used. Although th...

Problems solved by technology

[0002] At present, most domestic single-core degaussing cables are insulated with conventional ethylene-propylene rubber or cross-linked polyethylene, and the sheath is made of conventional chlorosulfonated polyethylene rubber or polyurethane materials, which cannot effectively conduct the internal heat of the cable and have a short service life.

The degaussing cable supporting the vehicle degaussing equipment is produced with silicone rubber insulation and sheath. Although the high temperature resistance of silicone rubber can effectively increase the current carrying capacity of the cable, the internal heat cannot be conducted and the strength and wear resistance of the silicone rubber material are average. Poor, easy to wear and scrap during long-term dragging

In addition, polyurethane sheath materials are also used. Although the wear resistance is greatly improved, the temperature resistance level of the cable is also reduced, and the current carrying capacity of the cable is reduced.

[0003] During the degaussing process of the ship, a large current is often passed through. Since the energized current far exceeds the rated current-carrying capacity of the cable, the conductor heats up severely during operation, and the air in the insulating layer is heated and expands, which may easily cause the cable to bulge and be scrapped.
