Patent ID: 8047866

Claim:
A transmission cable assembly comprising: a transmission cable having a high-voltage wire and an insulation jacket enclosing an outer surface of said high-voltage wire; a first connector having a first cap coupled to an end of said transmission cable and a first fitting sleeve extending from an end of said first cap; a second connector having a second cap coupled to an opposite end of said transmission cable and a second fitting sleeve extending from an end of said second cap; and a grounding unit made of an electrically conductive substance and having a grounding layer and a grounding wire, said grounding layer having a metallic tape that shows electrical conductivity and wrapped to completely cover said insulation jacket and partly enclose surfaces of said first and second connectors; whereby negative magnetically inductive impedance induced during transmission of a high voltage through said transmission cable will be conducted through said grounding layer and said grounding wire of said grounding unit to an engine body thereby reducing said impedance.
