When determining the specification of wire and cable (conductor cross-section), the selection conditions such as heat generation, voltage loss, econom

Power system: The wire and cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables

The main characteristics of this type of product are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire,

The wire and cable used in the information transmission system mainly include local telephone cable, TV cable, electronic cable, radio frequency cable

The cable is usually a rope-like cable formed by twisting several or several groups of conductors [at least two each group]. Each group of conductors

At present, the popular LVDS technical specifications have two standards: one is TIA / EIA (Telecommunications Industry Alliance / Electronic Industry

A signal transmission mode proposed by National Semiconductor in 1994 is a level standard. The LVDS interface, also known as the RS-644 bus interface,

Protected socket: External electronic devices do not need to be plugged in and out directly on the host computer, which not only protects the interfac

The USB extension cable is mainly composed of two parts: a network cable and two USB interfaces. The interface is connected to both ends of the networ
