Description

Novel ship shore connecting cable

Technical Field

The present invention relates to the construction of cables.

Background

In recent years, with the strong advocation of port cleaning in China, the environment protection force for areas such as ships and ports is enhanced, when the ships stop at the wharf, the self-contained auxiliary generator on the ships is stopped, and a land power supply is used for supplying power to a main shipborne system, namely a shore power system technology, wherein the shore power system technology is not only a new power transmission and energy configuration technology, but also an important way for effectively reducing the pollution of the ship ports and realizing energy conservation and emission reduction.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art, and provides a novel ship-shore connecting cable which can meet the matched use of a system device from a land power supply to a ship on shore and can meet the field work requirement.

The purpose of the utility model is realized as follows: the novel ship shore connection cable is a cable core consisting of three power wire cores, a ground wire core, a pair of control wire cores and a pair of communication wire cores; the power wire core comprises a power wire core tinned copper conductor on the inner layer and a power wire core ethylene-propylene insulating layer on the outer layer; the ground wire core comprises an inner layer of ground wire core tinned copper conductor and an outer layer of ground wire core ethylene-propylene insulating layer; the control wire core comprises a control wire core tinned copper conductor on the inner layer and a control wire core ethylene-propylene insulating layer on the outer layer; the communication wire core comprises an inner communication wire core tinned copper conductor and an outer communication wire core ethylene propylene insulating layer; and a flame-retardant halogen-free belt reinforcing layer is wound outside the cable core, a fiber reinforcing layer is woven outside the flame-retardant halogen-free belt reinforcing layer, and a sheath is extruded outside the fiber reinforcing layer.

A pair of control cores and a pair of communication cores of the present invention are arranged together.

The sheath is made of high-strength chloroprene rubber material.

The sheath is made of low-smoke halogen-free flame-retardant polyurethane material.

The utility model has the beneficial effects that: whole cable core is by 3 main +1 vice power cords, 1 to control core, 1 adopts the concentric type to constitute jointly to the communication sinle silk, and whole cable is equipped with tin-plated copper conductor, insulating layer from inside to outside in proper order, winds the package enhancement layer, the enhancement layer is woven to the fibre, the sheath, and wherein a pair of control sinle silk is adjacent together with a pair of communication line, not only reduces the power line and produces the electromagnetic wave after the circular telegram and to 2 interference to the low frequency line, has increased the stability of whole structure simultaneously. Each wire core is provided with an insulating layer, so that the insulating effect is good. The product has compact structure, simple manufacturing process and extremely convenient installation, use and maintenance.

The cable conductor has the advantages of flame retardance, halogen free, flexibility, weather resistance, wear resistance, dragging resistance, salt mist resistance, sunlight aging resistance, strong physical and mechanical properties and the like, the long-term allowable working temperature of the cable conductor is up to 90 ℃, the use environment temperature is not lower than-40 ℃, and the installation and laying temperature is not lower than-25 ℃.
