Cable and manufacturing method thereof

The invention relates to a cable and a manufacturing method thereof, the cable comprises an inner core, a shielding layer and ground wires, the shielding layer comprises a copper foil mylar layer, an aluminum foil mylar layer and a colored mylar layer, the copper foil mylar layer longitudinally wraps the outer side of an inner sheath, the ground wires are arranged on the two sides of the copper foil mylar layer, and the colored mylar layer is arranged on the outer side of the inner sheath. The aluminum foil mylar layer and the color mylar layer wrap the outer side of the ground wire, so that the overlapping ratio of the cable is stable, the characteristics are stable, and the maximum indication loss of the cable is reduced. 本发明涉及一电缆线及其制作方法，所述电缆线包括一内芯、一屏蔽层和一地线，所述屏蔽层包括一铜箔麦拉层、一铝箔麦拉层和一彩色麦拉层，所述铜箔麦拉层纵包于所述内护套外侧，所述地线被设置于所述铜箔麦拉层两侧，所述铝箔麦拉层和所述彩色麦拉层绕包于所述地线外侧，使的所述电缆线的重叠率稳定，特性稳定，使得所述电缆线的最大指示损耗减小。
