Abstract
The invention relates to a crosslinked polyethylene insulation shielding type cable for a frequency changer, which comprises an outer jacket layer (5) that is internally provided with a copper wire weaved shielding layer (4). The copper wire weaved shielding layer (4) is internally provided with a wrapping layer (3) which is provided with three phase lines. Each phase line comprises a copper conductor (1) and a crosslinked polyethylene phase line insulating layer (2). Ground wires are uniformly among the three phase lines. Each ground line comprises a ground line conductor (6) and a crosslinked polyethylene ground line insulating layer (7). Filling layers (8) are arranged among the phase lines, the ground lines and the wrapping layer (3). The copper wire weaved shielding layer (4) is weaved by copper wires that have thickness of 0.1-0.2mm. The filling layers (8) use polypropylene ropes and glass fiber ropes as fillers. The outer jacket layer (5) is extruded by using halogen free low smoke polyolefin materials as raw material.
Description
Technical field
The present invention relates to a kind of Cable for frequency changer, especially adopt crosslinked polyetylene insulated shield type Cable for frequency changer.
Background technology
To be the on-off action that utilizes power semiconductor device be transformed to the electric energy control device of another frequency with power frequency supply with frequency converter, and number of applications is arranged in industry.Frequency converter produces very big interference and influence near the electromagnetic field the Cable for frequency changer when the switching current frequency, cause signal disorder and short circuit, the work of frequency converter is produced have a strong impact on.
Summary of the invention
The problem that the present invention will solve provides a kind of crosslinked polyetylene insulated shield type Cable for frequency changer; Can be good at preventing that near the electromagnetic field of cable is interfered because of the use of frequency converter; Thereby avoid causing communication accidents such as signal disorder and short circuit, improved the Cable for frequency changer reliability of operation.
In order to address the above problem, the present invention realizes through following technical scheme.
A kind of crosslinked polyetylene insulated shield type Cable for frequency changer of the present invention; Comprise external sheath layer; Be provided with the copper wire woven shield in the said external sheath layer, in said copper wire woven shield, be provided with lapping layer, in said lapping layer, be provided with three phase lines; Every phase line comprises copper conductor and crosslinked polyethylene line insulating layer mutually; Be evenly equipped with a ground wire between any two in said three phase lines, every ground wire comprises gnd conductor and crosslinked polyethylene ground line insulating layer, is provided with packed layer between said phase line, ground wire and the said lapping layer.
Further improvement of the present invention is: said copper wire woven shield adopts the braiding of 0.1-0.2mm thin copper wire to form.
Further improvement of the present invention is: said packed layer adopts polypropylene rope and glass cord to make filler.
Further improvement of the present invention is: said external sheath layer employing is extruded by the low smoke, zero halogen polyolefine material and forms.
Compared with prior art; The present invention has guaranteed the shielding of cable and the effect of insulation from structure; This kind cable is primarily aimed at insulation and shields two and makes a little louder, can be good at preventing that near the electromagnetic field of cable is interfered because of the use of frequency converter, thereby avoids causing communication accidents such as signal disorder and short circuit; And the low smoke, zero halogen polyolefine material has good insulation flame retardant effect, can prevent because of the aging electric power accidents such as electric shock that cause of cable.Therefore in the useful life that can improve Cable for frequency changer greatly, improved the Cable for frequency changer reliability of operation.
