Pressure-resistant wear-resistant composite low-temperature-resistant ship shore power cable

Abstract

The invention relates to a pressure-resistant wear-resistant composite low-temperature-resistant ship shore power cable and belongs to the technical field of cables. The shore power cable of the present invention comprises a main wire core, a ground wire core, a control wire core, a fiber combination unit and a filling core, wherein the main wire core comprises a main wire core conductor, a conductor shielding layer, an insulating layer and an insulating shielding layer; the ground wire core comprises a ground wire core conductor and a semiconducting layer extruded outside the ground wire coreconductor; the fiber combination unit comprises a fiber, a fiber loose sleeve, a fiber inner shield, a fiber outer shield. The main wire core, the ground wire core, the control wire core, a fiber combination unit, and the filling core are twisted together to form a cable, and then the inner sheath is extruded. The inner sheath is provided with a fiber weaving reinforcing layer and an outer sheath. The main wire core further includes a metal shielding layer. The outer sheath is also successively provided with a TPEE pressure-resistant protective layer and a Dyneema wrapping tape. The ship shore power cable of the invention can simultaneously transmit power, control signals and communication signals, realizes high-voltage large-capacity power supply on a ship, and realizes information management.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a compression-resistant and wear-resistant compound type low-temperature-resistant shore power cable for ships. Background technique [0002] Shore power cable for ships means that when the ship is in port, stop using the engine on the ship and switch to land power to supply power through the shore power cable for ships. All power consumption such as lighting, air conditioning, and equipment on the ship Guaranteed by shore power, this has significant economic, social and environmental benefits for energy conservation, emission reduction, green economy and environmental governance. There are some problems and shortcomings in the existing technology: (1) The existing shore power cable communication for ships is separated from power transmission and information monitoring, and only has a single power transmission function, which cannot realize the ability to transmit cont...

AI Technical Summary

Problems solved by technology

There are some problems and shortcomings in the existing technology: (1) The existing shore power cable communication for ships is separated from power transmission and information monitoring, and only has a single power transmission function, which cannot realize the ability to transmit control and communication signals. When laying two or more different types of control cables and communication cables

It is impossible to realize the effective multi-system and multi-network integration of the power transmission system, control system and communication system, and it cannot meet the needs of intelligent ship control systems. At the same time, the cost of use is high, and the use effect is not very good, the safety is poor, and the use time is not long. long

(2) Existing power cables, control cables, and communication cables do not have functions such as torsion resistance, pull resistance, and dragging during retraction and use, and are prone to core breakage and other phenomena

(3) During the use of existing cables, the control core and communication core are flattened due to external pressure, which affects the performance of the cable
