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...

1. Polyvinyl chloride (PVC) PVC is a cheap and soft material. By adding various materials, it can have heat resistance and oil resistance. The biggest feature is flame retardant, so it is widely used in fire protection applications. PVC is one of the largest plastic products in the world. It is che... READ MORE
The previous audio lines used 2 lines, because the transmission distance is short, and it is baseband transmission, so the second line can be satisfied. For example, early telephones. But later people's requirements increased, hoping to extend the transmission distance, so an amplifier was added in... READ MORE
1. AC three-phase circuit: A phase: yellow. Phase B: Green. Phase C: red. Neutral or neutral, light blue. Safety ground wire: yellow and green. 2. AC circuits connected with twin-core wires or twisted-pair wires: red and black in parallel. Third, the DC circuit: positive: brown. Negative: blue. Gr... READ MORE
The use of the wire connector is very simple. We strip the insulation layer of about 10mm from the wire according to the nominal length, then lift the operating rod, put the wire into the connector and release the operating rod. Compared with the method of connecting with electrical tape, connecting... READ MORE
1. Insulation material (shell) of wire connector: Nylon 66 (resistance to leakage current breakdown, elasticity, rigidity, corrosion resistance, environmental protection, no halogen and formaldehyde. Temperature -35℃-105℃). 2. Pressure reed material: steel (cold stamping (the die installed on the p... READ MORE
1. Definition Audio cables are generally used for Line In and Line Out. They pass signals with low current and low power, and have high impedance and are easily interfered. Therefore, they are generally shielded lines, but the lines are generally thinner. Speaker wire is also called speaker wire, a... READ MORE
1. The cable consists of 2 or 4 insulated conductors twisted into a 2-wire group or a 4-wire group with an appropriate twist. For the 4-wire group, when viewed from the cross section, when the 4 wires are in a square shape, we call it a star-quad 4-wire group, in which the 2 wires on the diagonal fo... READ MORE
The types of cables are as follows:(1) Electromagnetic wire: It is a coil or winding used for motors, electrical appliances and electrical instruments, and has achieved electromagnetic energy conversion, also known as winding wire. According to the material, structure, heat resistance grade and use ... READ MORE
Lotus head audio cable welding method: Divide the audio cable into two, weld the left and right channels and cover them with heat shrink tubes for protection. 1. The types of audio cables can be divided into two categories, "audio electrical signal cables" and "audio optical signal cables", among w... READ MORE
