Cable dispensing system
First Claim
1. A cable dispensing system for use in high-voltage electrical applications, comprising:
- a stator comprising;
multiple parallel insulating discs fixedly attached to one another; and
multiple parallel coils of flexible non-insulated cable, where each of the parallel coils is separated from an adjacent coil by one of the insulating discs;
a housing assembly at least partially enclosing the stator and parallel coils, where the housing and the stator are configured to rotate relative to one another;
a cable coupled to the housing assembly; and
a retraction mechanism distinct from the multiple parallel coils,wherein the retraction mechanism is configured to rewind the cable around the housing assembly.

Abstract
The cable dispensing system includes multiple parallel coils of flexible non-insulated cables separated by multiple parallel insulating discs. The insulating discs have hubs to which the inner portions of the coils are fixedly coupled. The insulating discs and coils are disposed within a housing, which is rotatably coupled to the multiple parallel insulating discs and fixedly coupled to each outer portion of the multiple coils. The cables comprising the coils are routed from the inner portions through tunnels, which extend through the insulating discs in paths parallel to the axis of the parallel insulating discs. When cords attached to the housing are extended, the coils become wound, creating an electrical short between adjacent loops of the spiral coil. The shorter conductive path reduces the amount of energy that is lost as heat.
