6. Shielded control cables

Both to prevent the cable itself in the course of the operation of the high level of harmonic waves and other electromagnetic radiation on the surrounding area. harmonics and other electromagnetic radiation on the surrounding equipment, but also can effectively prevent the outside electromagnetic signals on the power supply cable interference shielded power flexible cable, including the conductor, insulation layer, filling layer, shielding layer, cable ties and sheath layer, the conductor includes three-core dominant conductor and the fourth core zero-sequence conductor, characterized in that: it also includes an isolation layer located in the cable ties and shielding layer, and the isolation layer outside the shielding layer and the sheath layer, the practical new type has the advantage of being able to prevent the interference of the cable itself during operation. Layer, the utility model has a low reactance value, with a high level of resistance to electromagnetic interference and inhibit the ability to radiate electromagnetic interference to the surrounding space, and soft and easy to bend, the production process is simple, cost-effective, and can meet the electrified railroad, inverter drive and a variety of other power supply cables have stringent shielding requirements and frequent movement of the use of the place requirements.
