Abstract
The utility model relates to a private cable for a silicon rubber insulation, shielding and high-temperature resisting frequency converter provided with a silicon rubber sheath. The private cable comprises a cable core and the silicon rubber sheath, wherein the cable core is internally provided with a plurality of leads and an electric power center line; the leads are formed in a way that silicon rubber insulation layers are coated outside conductors; the cable core is internally provided with glass fiber filler; and a belting layer, a silicon rubber inner protective layer, a braided copper wire shielding layer and a copper belt wrapped shielding layer are sequentially arranged between the cable core and the silicon rubber sheath. The private cable has good shielding performance, can effectively solve the problem of electromagnetic interference to the surrounding environment and has better capacity for resisting the external electromagnetic and static interference; the high-temperature resistance and the flame retardant property are better, therefore, the private cable can be used for a long time at the temperature of 180 DEG C, so as to meet the using requirement in the high-temperature environment.
Description
Technical field
The utility model relates to a kind of power cable, especially a kind of shielding, high-temperature resistant frequency converter private cable.
Background technology
The frequency converter private cable is the stube cable that connects frequency converter and alternating-current variable frequency motor, and in actual use, this frequency converter private cable can produce stronger frequency electromagnetic waves outwards to be launched, and surrounding environment is produced electromagnetic interference.The shielding properties of existing frequency converter private cable is difficult to solve the problem that surrounding environment is produced electromagnetic interference, and its resistance to elevated temperatures also is difficult to satisfy the instructions for use of hot environment.
Summary of the invention
In order to overcome the deficiency of existing frequency converter private cable, the purpose of this utility model provides a kind of silicon rubber insulation, silicone rubber jacket, shielding, high-temperature resistant frequency converter private cable.
A kind of silicon rubber insulation that the utility model provides, silicone rubber jacket, shielding, high-temperature resistant frequency converter private cable, comprise cable core and silicon rubber oversheath, have several lead and power center lines that silicone rubber insulation layer constitutes that outside conductor, coat in the cable core, in cable core, be provided with the glass fibre filler, between cable core and silicon rubber oversheath, be provided with belting layer, silicon rubber sheath, copper wire woven shield, copper strips lapped shielding layer successively.
The beneficial effects of the utility model are: advantages of good shielding performance, can effectively solve the problem that surrounding environment is produced electromagnetic interference, and also have anti-preferably extraneous electromagnetism and electrostatic interference ability; High temperature resistant, fire resistance is good, can use for a long time under 180 ℃ high temperature, can satisfy the instructions for use of hot environment.
