摘要：【中文】本发明公开了一种预分支电缆，其要点是：包括主干线电缆、分支电缆和连接接头。主干线电缆和分支电缆的结构相同，均包括电缆导体、电缆绝缘层、电缆屏蔽层和电缆护套层。分支电缆的电缆导体的截面积小于主干线电缆的电缆导体的截面积。连接接头包括导体连接金具、金具绝缘层、金具屏蔽层和金具护套层。分支电缆有两根或三根，各分支电缆通过连接接头与主干线电缆固定连接且电连接。连接接头的金具绝缘层与各电缆的电缆绝缘层连成一体。连接接头的金具屏蔽层与各电缆的电缆屏蔽层覆盖搭接。连接接头的金具护套层与各电缆的电缆护套层连成一体。 【EN】The invention discloses a pre-branch cable, which is characterized in that: including trunk cables, branch cables, and connection splices. The trunk cable and the branch cable have the same structure and respectively comprise a cable conductor, a cable insulation layer, a cable shielding layer and a cable sheath layer. The cross-sectional area of the cable conductor of the branch cable is smaller than that of the main line cable. The connecting joint comprises a conductor connecting hardware fitting, a hardware fitting insulating layer, a hardware fitting shielding layer and a hardware fitting protecting sleeve layer. The branch cables are two or three, and each branch cable is fixedly connected and electrically connected with the main line cable through a connecting joint. The hardware fitting insulating layer of the connecting joint is connected with the cable insulating layer of each cable into a whole. And the hardware fitting shielding layer of the connecting joint is in overlapping joint with the cable shielding layer of each cable in a covering manner. The hardware fitting sheath layer of the connecting joint is connected with the cable sheath layer of each cable into a whole.
