Twisted pair (TP) is one of the most commonly used transmission media in integrated wiring projects. It is composed of two copper wires with an insulating protective layer. Two insulated copper wires are twisted together at a certain density, and the radio waves radiated by each wire during transmis... READ MORE
Lotus head audio cable is a kind of audio cable. The lotus interface RCA head, commonly known as lotus cable, is suitable for connecting vcd, dvd, television, cassette player, cd, etc. and speakers, amplifiers, mixers and transmitting their audio signals. It is widely used in recording studios, stag... READ MORE
PVC sheath On the surface, the regular "unevenness" of the braided net can be seen in the compression, indicating that the processing technology is good, and there will be no relative sliding, and it is a good cable. The appearance is smooth, the "unevenness" of the compressed braid is not visible, ... READ MORE
[Same point]1. The characteristic impedance is the same-75 ohms;2. The outer sheath, shielding layer structure, insulating layer outer diameter, number selection, material selection, shielding layer number, etc. are basically the same; [difference]1. Different physical properties of the insulating l... READ MORE
AV lineThis is the oldest video cable that transmits analog video signals. Both ends are lotus heads (RCA heads). Both DVD players and TVs will have this kind of interface. This kind of cable is not required for decoration;S terminal lineA video cable with a better quality than the AV cable appeared... READ MORE
4. Regarding high braided cables, generally refer to cables above 96-128 braid. The obvious characteristics of high-stranded cables are: the shielding layer has low DC resistance, and the low-frequency attenuation below 200khz is reduced, which is beneficial to suppress low-frequency interference. T... READ MORE

The video cable is used to transmit video signals. It is a coaxial cable used to transmit video baseband analog signals. Video cables generally have two impedances of 75 ohms and 50 ohms, and can also be roughly subdivided into -3, -5, -7, -9 and other models.Video cables are divided into SYV and SY... READ MORE
Audio enthusiasts are very particular about the choice of speaker cable. I have heard that there are many people who spend more than 10,000 yuan to buy a cable. The other extreme of the speaker cable is to just find a wire to connect it to and make a sound. Let us leave these two extremes and look a... READ MORE
Speaker cableThe speaker cable is used to connect the power amplifier and the speaker. The current signal flowing in it is much larger than the aforementioned video cable and audio cable. Because of the large signal amplitude, this kind of cable often has no shielding layer. For this kind of cable, ... READ MORE
