The one or more electric actuators are configured to adjust one or more components of a cable pressure control equipment (PCE) stack. ## Claims ### Claim 1 A system, comprising: one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack, wherein a first control signal of the one or more control signals instructs supply of the electric power to a stuffing box actuator of the one or more electric actuators to adjust a packing material of a stuffing box of the one or more components, wherein a second control signal of the one or more control signals instructs supply of the electric power to a winch actuator of the one or more electric actuators to adjust a rate of rotation of a drum of a winch of the one or more components, and wherein a third control signal of the one or more control signals instructs supply of the electric power to a valve actuator of the one or more electric actuators to adjust a ram of a valve of the one or more components. ### Claim 2 (depends on 1) The system of claim 1, comprising the power supply. ### Claim 3 (depends on 1) The system of claim 1, comprising the one or more electric actuators and the one or more components of the cable PCE stack, wherein the one or more components comprise the stuffing box, the valve, and the winch. ### Claim 4 (depends on 1) The system of claim 1, comprising one or more sensors configured to monitor one or more conditions of the cable PCE stack and to provide one or more sensor signals indicative of the one or more conditions to the one or more processors. ### Claim 5 (depends on 4) The system of claim 4, wherein the one or more processors are configured to process the one or more sensor signals and to provide the one or more control signals based on the one or more sensor signals. ### Claim 6 (depends on 4) The system of claim 4, wherein the one or more sensors comprise a leak sensor, a pressure sensor, and a position sensor. ### Claim 7 (depends on 1) The system of claim 1, comprising a cable extending through the cable PCE stack, wherein the cable comprises a wireline, slickline, coiled tubing, or spoolable rod. ### Claim 8 A system, comprising: one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack, wherein the one or more processors are configured to receive a leak signal from a leak sensor, determine whether a leak is present based on the leak signal, and provide a stuffing box control signal of the one or more control signals to supply the electric power to a stuffing box actuator of the one or more electric actuators to adjust a packing material of a stuffing box in response to determining that the leak is present. ### Claim 9 (depends on 8) The system of claim 8, wherein the one or more processors are configured to receive a position signal from a position sensor, determine whether a plate of a tool trap is driven to an open position by a tool within the cable PCE stack based on the position signal, and provide a winch control signal of the one or more control signals to supply the electric power to a winch actuator to reduce a rate at which the tool is withdrawn from the cable PCE stack in response to determining that the plate is driven to the open position by the tool. ### Claim 10 (depends on 8) The system of claim 8, wherein the one or more processors are configured to receive a first pressure signal from a first pressure sensor, receive a second pressure signal from a second pressure sensor, determine whether a seal formed by rams of a first valve is adequate based on the first pressure signal and the second pressure signal, provide a cable control signal of the one or more control signals to supply the electric power to a valve actuator to move rams of a second valve to a respective closed position in response to determining that the seal formed by the first valve is inadequate. ### Claim 11 (depends on 8) The system of claim 8, comprising the power supply. ### Claim 12 (depends on 8) The system of claim 8, comprising a cable extending through the cable PCE stack, wherein the cable comprises a wireline, slickline, coiled tubing, or spoolable rod. ### Claim 13 A method, comprising: generating, using one or more processors, one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack; generating, using the one or more processors, a first control signal of the one or more control signals to cause supply of the electric power to a stuffing box actuator of the one or more actuators to adjust a packing material of a stuffing box of the one or more components; generating, using the one or more processors, a second control signal of the one or more control signals to cause supply of the electric power to a winch actuator of the one or more actuators to adjust a rate of rotation of a drum of a winch of the one or more components; and generating, using the one or more processors, a third control signal of the one or more control signals to cause supply of electric power to a valve actuator of the one or more actuators to adjust a ram of a valve of the one or more components. ### Claim 14 (depends on 13) The method of claim 13, comprising: receiving, at the one or more processors, one or more signals from one or more sensors configured to monitor one or more conditions of the cable PCE stack; determining, using the one or more processors, the one or more conditions of the cable PCE stack; and providing the one or more control signals based on the one or more conditions of the cable PCE stack.
