Abstract
The utility model discloses a high-temperature resistant frequency converter cable. The high-temperature resistant frequency converter cable comprises a main wire core, an auxiliary wire core and a high-temperature resistant fluorine-containing inner lining layer, a copper tape wrapping and copper wire winding shielding layer and a fluorine-containing silicon rubber sheath which are wrapped outside the main wire core and the auxiliary wire core in sequence; and the main wire core and the auxiliary wire core comprise copper core conductors and fluorine-containing silicon rubber insulating layers wrapped outside the copper core conductors, and the main wire core is thicker than the auxiliary wire core. The high-temperature resistant frequency converter cable adopts the high-temperature resistant fluorine-containing inner lining layer and the copper tape wrapping and copper wire winding shielding layer for double-layer shielding, thereby achieving good anti-interference performance; and in addition, the adopted fluorine-containing silicon rubber has good temperature resistance and mechanical property, so that the high-temperature resistant frequency converter cable can normally work at the temperature ranging from minus 50 DEG C to 180 DEG C, can prolong the service life effectively, further saves the production cost and is particularly suitable for connecting wires for a frequency converter motor in the high-temperature environment.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of modified model function cable.
Background technology
Electric wire is meant the material that is used for electric power, communication and associated transport purposes.Along with the continuous expansion of industry sizes such as power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.To the performance requirement difference of its each side, wherein, have relatively high expectations to the interference free performance of cable by frequency-changing cable under different operating positions for cable, and in addition, heat resistance is also very important, and traditional cable still can not reach good anti-interference and heatproof effect at present.The deriving of electric wire/new product mainly be in response to occasion, application requirements is different and the convenience of equipment and reduce the requirement of equipment cost etc., and adopt new material, special material or change product structure or improve technological requirement and produce.
The utility model content
The purpose of this utility model provides a kind of high temperature resistant frequency-changing cable, has the characteristics of good interference free performance, high temperature resistant and long service life.
For achieving the above object, by the following technical solutions:
A kind of high temperature resistant frequency-changing cable, comprise master core, by-pass core, and the wrapped copper wire of fluorine-containing high-temperature resistant inner lining layer, copper strips that is wrapped in successively outside master core and the by-pass core twines screen and fluorine silicon rubber sheath, wherein, described master core and by-pass core are by the copper core conductor and wrap up its outer fluorine silicon rubber insulation and form, and described master core is thick than the by-pass core.
Described master core is one or more strands of.
Described by-pass core is one or more strands of.
The utility model adopts fluorine-containing high-temperature resistant inner lining layer and the wrapped copper wire of copper strips to twine the double layer screen of screen, has good anti-interference effect; In addition, the fluorine silicon rubber that insulating barrier and sheath adopted has good heat resistance and mechanical performance, realized the operate as normal of the utility model under-50 ℃～180 ℃, and effectively prolonged useful life, thereby saved production cost, be specially adapted to the variable-frequency motor connection line under the hot environment.
