Superconducting cables used in overhead cables

Basic parts and basic materials power electronic devices power electronics have entered the fourth generation of a smart era. The basic trend is to reduce the high-voltage large-capacity fast turn-on voltage, low-loss high-frequency, and high reliability intelligent and integrated development of new devices and process refinement. Internationally present, the main focus is the power of intelligent power module power Power IC (integrated gate commutated thyristors and new devices.

In the bare terms, is capable of producing a copper alloy suitable for high-speed railway lines, overhead cables are widely used in a large section of aluminum cable wires and other electrical equipment, power lines special cables widely used fire retardant cable, in order to meet environmental requirements, crosslinked polyolefin and cross-linked polyethylene cable replaced by the trend to accelerate communications cable has a non-zero dispersion shifted single-mode fiber type development, access has been widely used a long-distance fiber optic cable transmission lines has been applied, the Danish cable lines into operation Japanese cable line coming into operation.

Superconducting power transmission cable in the application has made substantial progress in productivity and the value of the winding wire to achieve the degree of automation has been greatly improved, no one workshop began, and inverter motor enameled began to be widely used.

Scientific and technological levels and trends of domestic electrical equipment in China's power industry are currently restructuring period, on the one hand, to adjust the ratio of installed capacity of nuclear fire and water and new energy power generation, on the other hand, we will focus on the development of clean coal power generation technology supercritical generating units Wind power technology Power and environmental technology.
