Cable shielding in the high voltage cable assembly The shielding performance of the high-voltage cable harness is very important. The shielding performance of the connector in the wiring harness we have analyzed in detail in the high -pressure connector of the car, and the shielding of the cable is more complicated. The central conductor part of the cable is currently selected as a condu...

Solar cables, also known as photovoltaic cables or photovoltaic wires, are single-core wires used to interconnect solar panels in a photovoltaic system. Photovoltaic systems, or solar panels, capture sunlight in order to generate electricity through an energy conversion process. Electricity is generated on the panel, and wiring is needed to transmit it back to the collection point or device. Solar...
