Problems solved by technology

[0003] The existing technology is mainly to increase the current carrying capacity of the cable by increasing the rated working temperature of the insulation and sheath material. However, due to the small thermal resistance coefficient of the existing material, the surface temperature of the cable is very high, which can reach 110 ° C. The heat dissipation in the narrow space of the ship is not smooth, causing the ambient te...

Abstract

The invention relates to a vessel high-carrying-capacity low-surface-temperature-rise shielding cable and a manufacturing method thereof. A high-thermal-resistance-coefficient inflaming retarding fire-resistant insulating layer evenly wraps the periphery of a twisted copper conductor in a squeezing mode, a filament glass fiber woven reinforcement layer wraps the periphery of the high-thermal-resistance-coefficient inflaming retarding fire-resistant insulating layer to form shielding cable insulating cable cores, the shielding cable insulating cable cores are twisted to form a shielding cable core, and gaps among the shielding cable insulating cable cores are filled with high-thermal-resistance-coefficient inflaming retarding fire-resistant filling cores so that the cable core can be rounded off. A high-thermal-resistance-coefficient inflaming retarding fire-resistant longitudinal wrapping belt wraps the periphery of the shielding cable core, a shielding layer wraps the periphery of the high-thermal-resistance-coefficient inflaming retarding fire-resistant longitudinal wrapping belt, and a high-thermal-resistance-coefficient chemical crosslinking polyolefin outer sheath wraps the periphery of the shielding layer in a squeezing mode. According to the shielding cable, the temperature of the outer wall of the cable can be reduced, and the carrying capacity can be improved under the condition that the cross sections of conductors are the same.

Description

technical field [0001] The invention relates to a shielded cable, in particular to a shielded cable with high ampacity and low surface temperature rise for ships. The invention also relates to a manufacturing method of a shielded cable with high ampacity and low surface temperature rise for ships. Background technique [0002] As the country pays more attention to the development and utilization of marine energy, a large number of new ships have been built. Since most of the ships sail in the open sea and spend a long time at sea, it is necessary to reduce the weight of the ship itself and increase the payload of the ship. As the power transmission equipment of the ship, the weight of the cable has a great influence on the load of the ship. The weight of the cable is related to the cross-sectional area of ​​the conductor, and the cross-sectional area of ​​the conductor is mainly determined by the current-carrying capacity. In addition to the conductor material and cross-sec...
