Abstract
A kind of low-impedance cable, including outer jacket, flowing coating of cooling liquid, insulating layer, filled layer, the cool but liquid layer in center, center cable core and cable core, flowing coating of cooling liquid is arranged on the inside of outer jacket, insulating layer is arranged on the inside of flowing coating of cooling liquid, filled layer is arranged on the inside of insulating layer, cable core is arranged inside filled layer, center cable core is arranged on the inside of filled layer, on the inside of the centrally disposed cable core of the cool but liquid layer in center, the cool but liquid layer of flowing coating of cooling liquid and center is liquid hydrogen or liquid nitrogen, and center cable core is pure copper material.The low-impedance cable has good heat-sinking capability, quick impacting with high pressure can preferably be resisted, avoid the insulation Problem of Failure of cable long-term work appearance, ensure that low-impedance cable works normally, lower route power consumption, the quality for improving low-impedance cable has reached the requirement of low-impedance cable.
Description
Technical field
The utility model relates to cable design manufacturing technology fields, more particularly to a kind of low-impedance cable.
Background technique
With the continuous improvement of scientific and technological level, cable design manufacturing technology level is also greatly improved.Electricity
Cable is usually by several or several groups of conducting wires form, and is made of the conductor and external insulating protective layer of one or more mutually insulated,
Electric power or information are transferred to the conducting wire at another place from one.Or similar rope as several or made of several groups of wire strandings
Cable, mutually insulated between every group of conducting wire, and be often twisted into around a center, entire outside is surrounded by the covering of high-insulation
Layer.Cable has interior energization, the feature of external insulation.Cable has power cable, control cable, compensating cable, shielded cable, high temperature
Cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..
In recent years, with the continuous development of cable design manufacturing technology, cable is required also higher and higher.Low-impedance cable is because of its impedance
Low resistance with lower power consumption, off-energy is small, insulation and thermal insulation is functional and have preferably resist impacting with high pressure ability,
The range used is more and more wider, and usage amount is more and more.Currently, common low-impedance cable structure is single, usually only one layer
Shielded layer, one layer of heat dissipating layer and a layer insulating, although being provided with the basic performance of low-impedance cable.It often occurs, however, that absolutely
Thermal failure leads to cable work hot soak condition, loses and resists impacting with high pressure ability, causes to increase power consumption, influence
The service performance of low-impedance cable, reduces the quality of low-impedance cable, the requirement of low-impedance cable is not achieved.
Utility model content
The utility model main purpose is to solve above insufficient, provides that a kind of heat-sinking capability is strong, and insulation effect is good, mentions
Height uses the low-impedance cable of quality.
A kind of low-impedance cable, including outer jacket, flowing coating of cooling liquid, insulating layer, filled layer, the cool but liquid layer in center, middle electrocardio
Cable core and cable core, flowing coating of cooling liquid are arranged on the inside of outer jacket, and insulating layer is arranged on the inside of flowing coating of cooling liquid, filled layer setting
On the inside of insulating layer, cable core is arranged inside filled layer, and center cable core is arranged on the inside of filled layer, the cool but liquid in center
On the inside of the centrally disposed cable core of layer, the cool but liquid layer of flowing coating of cooling liquid and center is liquid hydrogen or liquid nitrogen, and center cable core is
Pure copper material.
Further, the cable core quantity of the low-impedance cable is 2 to 8, is to be arranged in inside filled layer.
Further, the filled layer of the low-impedance cable is ceramic polyolefine material.
Compared with the existing technology, the advantageous effects that the utility model obtains are as follows: the low-impedance cable has good
Heat-sinking capability can preferably resist quick impacting with high pressure, avoid the insulation Problem of Failure of cable long-term work appearance, it is ensured that
Low-impedance cable normal work, lower route power consumption, improves the quality of low-impedance cable, has reached low-impedance cable
Requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1, outer jacket in the figure；2, flowing coating of cooling liquid；3, insulating layer；4, filled layer；5, the cool but liquid layer in center；6, middle electrocardio

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining practical new
Type is not intended to limit the scope of the utility model.
A kind of low-impedance cable, including outer jacket 1, flowing coating of cooling liquid 2, insulating layer 3, filled layer 4, the cool but liquid layer 5 in center, in
Electrocardio cable core 6 and cable core 7, in 1 inside of outer jacket, insulating layer 3 is arranged in 2 inside of flowing coating of cooling liquid the setting of flowing coating of cooling liquid 2,
The setting of filled layer 4 is arranged inside filled layer 4 in 3 inside of insulating layer, cable core 7, and center cable core 6 is arranged in filled layer
4 insides, centrally disposed 6 inside of cable core of the cool but liquid layer in center 5, the cool but liquid layer 5 of flowing coating of cooling liquid 2 and center be liquid hydrogen or
Liquid nitrogen, center cable core 6 are pure copper material.
To make to adapt to a variety of demands, its applicability is improved.7 quantity of cable core of the low-impedance cable is 2 to 8,
To be arranged in inside filled layer 4.
To keep its durable, its service life is improved.The filled layer 4 of the low-impedance cable is ceramic polyolefin material
Material.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
