Abstract

The utility model discloses a power cable for a frequency converter. The power cable for the frequency converter comprises multiple cores; an outer wall of a cable conductor is provided with double insulation layers, the cable double insulation layers comprise an inner insulation layer and an outer insulation layer; a cable 3+3 structure core is arranged according to a main insulation core color order to guarantee a grounding core to be at a gap of two adjacent main cores; a cable shielding is braided by employing nickel-clad copper wire; the cable is armored by employing galvanized circular steel wire; and a double-layer cable sheath comprises an inner layer sheath and an outer layer sheath. The power cable for the frequency converter has improved performances of high temperature resistance, aging resistance, corrosion resistance, low temperature resistance and fire resistance, is enabled to have a wider application environment, further reduces medium loss in a use process, improves electrical performance and makes a transmission signal more stable and have no distortion, and thereby effective cable transmission is guaranteed.

Description

A kind of power cable for frequency converter
Technical field
The utility model relates to field of cables and especially relates to a kind of power cable for frequency converter.
Background technology
Present chemical industry, metallurgical, the employed tensile wear-resistant power cable for frequency converter in the fields such as electric power is in the operational environment requirement, has the tensile wear-resistant effect, mostly be at present interior monolayer plastic and do insulation, outer is individual layer flame-proof polyvinyl chloride sheath, this just causes the resistance to elevated temperatures of cable and anti-aging, corrosion resistant is turbid, low temperature resistant and fire-resistant degree is not high, especially chemical industry, metallurgical, the places such as electric power use the wear-resisting power cable for frequency converter of high-temperature-resistant, tensile to resistance to elevated temperatures and anti-aging, anti-tension, any problem can not appear in low temperature tolerance ability, and existing single-layer sheath formula structure can't satisfy above requirement.
The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model purpose is for a kind of wear-resisting power cable for frequency converter of high-temperature-resistant, tensile with the advantage such as simple in structure, easy to use, can the Effective Raise cable high temperature resistant, wear-resistant is provided.
The utility model is dealt with problems by the following technical solutions: a kind of power cable for frequency converter, it comprises by multicore and forming, described cable conductor outer wall is provided with double hyer insulation, described cable double hyer insulation is comprised of primary insulation and outer layer insulation, when arranging, presses described cable 3+3 structure core main insulation core look order, guarantee that the ground connection core is in the gap of adjacent two master cores, described cable shield adopts the nickel plating proof copper-wire braided, described cable adopts the galvanized steel bar silk to twine armouring, and described cable duplex sheath is comprised of internal layer sheath and external sheath layer.
Described primary insulation is perfluoroethylene-propylene (F46) insulation, and described outer layer insulation is fire-retardant butyronitrile polymer insulation material.
Described internal layer sheath is the fluorubber sheath, and described external sheath layer is fire-retardant butyronitrile polymer jacket material.
The utlity model has in sum following beneficial effect: strengthened cable high temperature resistant, anti-aging, corrosion resistant is turbid, low temperature resistant and fire resistance, make the environment for use of cable more extensive, and reduced dielectric loss in use, strengthened electrical property, make signal transmission more stable and undistorted, thereby ensure the effective transmission of cable.
