Abstract
The utility model relates to a crosslinked polyethylene insulating cable for a shielding frequency converter, which comprises an outer sheath layer (5). A copper wire braided shielding layer (4) is arranged in the outer sheath layer (5); a tapped covering (3) is arranged in the copper wire braided shielding layer (4); three phase lines are arranged in the tapped covering (3); each phase line comprises a copper conductor (1) and a crosslinked polyethylene phase line insulating layer (2); a ground wire is respectively arranged between each two of the three phase lines; each ground wire comprises a ground wire conductor (6) and a crosslinked polyethylene ground wire insulating layer (7); a filling layer (8) is arranged among the phase lines, the ground wires and the tapped covering (3); the copper wire braided shielding layer (4) is formed by braiding thin copper wires with the specifications of 0.1 to 0.2mm; polypropylene ropes and glass cords are used as fillers of the filling layer (8); and the outer sheath layer (5) is made of a halogen-free low-smoke polyolefin material. According to the utility model, the cable is structurally ensured to well prevent an electromagnetic field near the cable from being interfered due to the use of the frequency converter, so that communication accidents of signal disorder, short circuit and the like are avoided and the halogen-free low-smoke polyolefin material has a good insulation flame-retardant effect, and thus, the service life of the cable for the frequency converter can be greatly prolonged and the operation reliability of the cable for the frequency converter is improved.
Description
Technical field
The utility model relates to a kind of Cable for frequency changer, especially adopts 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 utility model 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.
