    Abstract: A torque-balanced, gas-blocking wireline cable and a method of making the cable includes an electrically conductive cable core for transmitting electrical power and surrounding inner and outer layers of a plurality of armor wires. Gas blocking is achieved by placing a soft polymer layer over the core before the inner wires are cabled thereon. The inner wires imbed partially into the soft polymer layer such that no gaps are left between the inner wires and the core. A second soft polymer layer is optionally extruded over the inner wires before the outer wires are applied. The second soft polymer layer fills any spaces between the inner and outer wire layers and prevents pressurized gas from infiltrating between the wires. The inner wires have larger diameters than the outer wires such that the inner wires carry approximately 60% of the load and torque imbalance is prevented.

    Abstract translation: 扭矩平衡的阻气电缆电缆和制造电缆的方法包括用于传输电力并围绕多个铠装线的内层和外层的导电电缆芯。 气体阻塞是通过将软聚合物层置于芯上而实现的，然后将内部电线连接在芯上。 内部线材部分地嵌入软质聚合物层中，使得内部线材和芯部之间没有间隙。 在施加外部电线之前，第二软聚合物层任选地在内部电线上挤出。 第二软聚合物层填充内部和外部线层之间的任何空间，并且防止加压气体渗入电线之间。 内部线材的直径大于外部线材，因此内部线材承载大约60％的负载，并且防止扭矩不平衡。
