中点连接线（又称中间连接线）用于两个扼流变压器中点之间、单扼流变压器中点与钢轨之间的连接。

   Midpoint connector or intermediate connector is used for the connection between midpoints of two impedance bonds and the connection between midpoint of single impedance bond and rail.

   产品线芯采用防腐防混的蜂窝状结构，外部是一层绝缘护套；线体与线鼻、塞钉焊接处进行二次注塑防护。产品具有良好的防水、防腐效果。
   The core of the product is designed to anticorrosive and anti-mix honeycomb structure with the exterior a layer of insulating sheath. The plastic injection is made at the place where the line is welded with cable lug and plug pin. The product has a good waterproof and anti-corrosion performance.

   连接线结构为两头铜环；连接线按标准长度或客户要求长度生产。
   The connector has two copper rings at both ends in structure. The connector is produced in standard length or customized upon client’s request.
   依据标准：TB/T 3205.2-2008《扼流变压器钢轨引接线、中点连接线、中点连接板 第2部分：中点连接线》。
