The electromagnetic noise environment of industrial sites is often very complicated, and the radiation or conduction of electromagnetic noise may seriously interfere with the normal operation of electromechanical equipment. In this process, an important carrier of electromagnetic noise is the various cables used in production line equipment.
Some of them are noise sources and some are disturbed objects. As a noise source, the cable will be like a radio transmitting antenna, spreading noise to the surrounding lines and equipment; as a victim, the cable will be like a receiving antenna, absorbing noise interference from other radiation sources.
To combat electromagnetic noise interference on electrical lines, a very important way is to use shielded cables. A shielded cable is a cable with one or more (mutually insulated) wires wrapped by a common conductive layer. This common conductive layer is the shielding layer of the cable, which is generally composed of braided strands of copper (or aluminum), non-woven spiral windings of copper tape, or conductive polymer layers.
Generally, there are two types of cable shielding: metal foil and woven mesh. The metal foil shielding layer usually uses a thin layer of aluminum attached to a carrier such as a polyester material to increase its strength and make it stronger. Cable aluminum foil can provide 100% wrapping coverage for the wires, and has a relatively good shielding performance.
1235-O aluminum foil and 8011-O aluminum foil are two common kinds of cable aluminum foil factory with a thickness of 0.1-0.2mm, which are commonly used in the manufacture of cable shielding foil.
