Abstract: A torque balanced conductor cable includes between three and six strands spiraled together with the torque exerted by the cable being approximately equal to the torque exerted by the strands. Each strand includes an insulated conductor as a core with steel wires stranded therearound and the insulation extending into the interstices of the strands. Another species includes insulated conductors positioned in the outer valleys of the cable and a sheath extruded over the entire assembly. This second species may be used with the first species or with cables in which the strands have a steel wire core member.

Abstract translation: 扭矩平衡导体电缆包括三到六根螺旋线的线，由电缆施加的扭矩大致等于由绞线施加的扭矩。 每条绞线包括绝缘导体作为核心，钢丝绞合在其周围，绝缘体延伸到线束的间隙。 另一种物质包括定位在电缆的外谷中的绝缘导体和在整个组件上挤出的护套。 该第二种可以与第一种或第二种物质一起使用，其中丝线具有钢丝芯部件。
