         6 . A compressor comprising:
 a fluid compressing device;   a shell containing the fluid compressing device; and   a wire feedthrough assembly located in an aperture in the shell, the wire feedthrough assembly including:
 a housing; 
 a body positioned in a passageway in the shell and connected to the housing to form a hermetic seal between the housing and the body; and a plurality of wires embedded in the body, each wire of the plurality of wires being individually hermetically sealed by the body, and at least one of the wires being connected to the fluid compressing device and configured to supply control signals to the fluid compressing device. 
   
     
     
         7 . The compressor according to  claim 6 , wherein the fluid compressing device includes a heater, and at least one of the wires supplies the control signals to the heater. 
     
     
         8 . The compressor according to  claim 7 , wherein the heater is configured to heat oil sump fluid in an oil sump, and the at least one of the wires supplies the control signals to the heater to control the heater to heat up the oil sump fluid. 
     
     
         9 . The compressor according to  claim 6 , wherein the fluid compressing device includes a compressor motor, and at least one of the wires supplies the control signals to the compressor motor. 
     
     
         10 . The compressor according to  claim 9 , wherein the at least one of the wires supplies the control signals to the compressor motor to turn the compressor motor on when a preset temperature threshold is reached. 
     
     
         11 . A compressor comprising:
 a shell containing the compressor motor;   a wire feedthrough assembly located in an aperture in the shell, the wire feedthrough assembly including:
 a housing; 
 a body positioned in a passageway in the housing and connected to the housing to form a hermetic seal between the housing and the body; and a plurality of wires embedded in the body, each wire of the plurality of wires being individually hermetically sealed by the body; and 
   a shield located on an outer surface of the shell and configured to protect the wire feedthrough from damage.   
     
     
         12 . The compressor according to  claim 11 , wherein the shield has a circular cross-sectional shape. 
     
     
         13 . The compressor according to  claim 11 , wherein the shield does not surround a full 360 degrees around the wire feedthrough assembly. 
     
     
         14 . The compressor according to  claim 11 , wherein the shield includes a cover that k parallel to the shell. 
     
     
         15 . The compressor according to  claim 14 , wherein the cover includes at least one hole to allow passage of the wires of the wire feedthrough assembly.
