A high frequency transmission cable is matched with a circuit board. The circuit board is equipped with a conducting portion and a grounding portion. The high frequency transmission cable includes a conducting wire, a first insulating layer surrounding the conducting wire, an aluminum foil layer and a second insulating layer. The aluminum foil layer surrounds the first insulating layer. An outer surface of the aluminum foil layer is a conducting surface. The second insulating layer surrounds the aluminum foil layer. The second insulating layer surrounds the conducting surface of the aluminum foil layer. The conducting wire is connected with the conducting portion. The conducting surface of the aluminum foil layer is connected with the grounding portion, so that the high frequency transmission cable has a grounding effect.

A vehicular vision system includes an ECU disposed at a vehicle and a front camera having a CMOS imaging sensor operable to capture image data. Image data captured by the imaging sensor of the front camera is conveyed from the front camera to the ECU via a single core coaxial cable. The front camera is in bidirectional communication with the ECU over the single core coaxial cable. The single core coaxial cable commonly carries (i) image data captured by the imaging sensor for processing at a data processor of the ECU and (ii) power from a DC power supply of the ECU to the front camera. Image data captured by the imaging sensor is serialized at a data serializer of the front camera and is transmitted to the ECU via the single core coaxial cable and is deserialized at the ECU by a data deserializer of the ECU.

The present disclosure provides insulated electrical conductors, e.g., wires, and methods for producing such insulated electrical conductors to combat partial discharge by enhancing bond strength between the electrical conductor and a base insulating thermoplastic layer (e.g., including a PAEK). Such insulated electrical conductors can include: an electrical conductor; an insulating coating on at least a portion of a surface of the electrical conductor; and an oxide layer between the electrical conductor and the insulating coating. Methods for producing such insulated electrical conductors can involve extrusion of an insulating polymer onto the electrical conductor under ambient atmosphere and a subsequent heat treatment step, which can also be conducted under ambient atmosphere.
