Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power li... READ MORE
Power carrier communication monitoring system anti-theft. Power carrier is a concept derived from the interdisciplinary discipline of power and communication. The power carrier communication method uses the signal transmission method in the wire and cable anti-theft system to load the detection carr... READ MORE
In the audio system, in order to achieve contact transmission and communication between devices, it must rely on the audio cable connected to it, which is composed of wires and connectors. It plays a very important role in the entire audio system, and now there are many types of audio cables used in... READ MORE
The video cable is used to transmit video signals. It is used to connect media playback devices and display devices. There are the following types of video cables: 1. AV cable: This is the oldest video cable that transmits analog video signals, with RCA connectors on both ends. 2. S-terminal cable:... READ MORE
1. Audio cables should have good contact and durability after multiple plugging and unplugging.If the contact is poor,it is easy to lead to poor sound or image signal quality or even breakage,which is unacceptable to consumers.When we use various audio-visual equipment,due to different reasons such ...

1. Anti-ultraviolet, anti-sun and aging means the same thing. The biggest reason for the aging of outdoor cables is ultraviolet radiation; 2. Other factors that affect the service life of the cable: It is resistant to rain shower, weak acid and alkali, high temperature, etc. It will inevitably be a... READ MORE
1. The length of the speaker cable should be 2m~2.5m, which is closer to the length of use, and there is a certain space. For example, if it exceeds 5m, it will reduce the sound range, reduce the aftertaste and strength of the music, and cause unnecessary waste. 2. When using a rigid beam speaker c... READ MORE
1. The standard level signal line refers to the connection line between the audio source and the power source. Its transmission level is about 1V, and it is also a shielded transmission line. This type of wire is the most widely used in the audio industry. Interestingly, wires made of different insu... READ MORE
1. Bare copper wire Bare wires and bare conductor products refer to conductive wires without insulation and sheath, which mainly include three series of products: bare single wire, bare stranded wire and profiled wire. (1). Copper-aluminum single wire: including soft copper single wire, hard copper... READ MORE
At present, the materials of audio cables are mainly copper wires and silver wires. Since copper wire is not very conductive, but really good conductive wire is very expensive, most manufacturers will make compromises by transferring other metals to the copper wire to improve the conductivity of the...
