1. what is the sheathed wire? The sheathed wire can be understood as two or three parallel BV wires (here refers to the BVV sheath wire), BV wires originally have insulation rubber, in three or two parallel BV wires and then coated with a layer of rubber, this layer of rubber is the sheathed wire. Sheath wire is also a common household wire, usually consisting of three or two cores. &n...

EV high-voltage cable introduction: On electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging and air conditioning power supply. It mainly includes battery system, power system, high-voltage electronic control system, charging system, high-voltage equipment and its harness system. The high-voltage line of electric vehicle is used...

SATA stands for Serial ATA. It is a type of computer bus that is mainly used for data transfer between the motherboard and mass storage devices such as hard disks and optical disk drives. This is a new type of hard disk interface completely different from serial PATAs, so named because of the serial mode of data transmission. SATA bus uses embedded clock signal, which has stronger error correction...

1. The voltage environment used is different. Eur-gauge power cords are used at 220V, while American gauge power cable usually work at 110V. 2. The core section of the US standard power cord is thicker than that of the European standard power cord. According to P=UI(P is the power, U is the voltage, and I is the current), the current passing through is higher because the working vol...

The BUSBAR design selection is not only as simple as considering the ability of overcurrent. Usually when designing a battery, the most considers is busbar, paying attention to its overcurrent ability and heat.   How do we judge when doing busbar design? It is a very important point to be warming. If we simply say how wide, how many layers thick, and how much the cross -sectional area, and th...

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...

Hazard of unqualified wire and cable Wire and cable is used to transmit power, transmit information and realize the electromagnetic energy conversion of a class of electrical products. In the process of spot check, found a large number of unqualified products, these inferior products to the normal operation of the power system buried many hidden dangers. 1, mark unqualified wire and cable. Mark is...

Testing cables at high voltages can help determine the presence of moisture, flux, or contaminants that may have penetrated the insulation or connector backshell breaks, and ensures that the insulation between wires can withstand temporary voltages higher than the normal working voltage offset without decomposing. The results of the high-voltage test usually show the insulation resistance between ...

Among the new energy vehicles (pure electric as an example) high voltage cable assemblies can be divided into 5 parts 1. Power battery high voltage cable: that is, the wiring bundle between the power battery and the high voltage box. 2. Motor controller cable: that is, the cable connecting the high voltage box to the motor controller. 3. Fast charging wire harness: connect the cable assembly ...
