Development of High-voltage DC Power Cables

HVDC has many advantages, such as low cost of paper, low line loss, no reactive power, easy power connection, and easy control and adjustment. Especially in long-distance transmission, DC power systems have been widely used. In the 1980s, China built a 500kV DC transmission line from Gezh

Analysis of the relationship between MHz and Mbps

Mbps is the unit of data traffic and MHz is the unit of frequency.

Hz (Hertz) refers to the BandWidth of the cable. It represents the number of oscillations of the electrical signal in the line per unit time. For example, the frequency bandwidth of Category 5 twisted pair is 100 MHz.
