Electric power transmission

Electric power transmission is the bulk transfer of electrical energy, from generating power plants to electrical substations located near demand centers. Different electric power transmission process used different electrical insulators. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution.

Transmission lines, when interconnected with each other, become transmission networks. The combined transmission and distribution network is known as the "power grid" in the some international countries, or just "the grid". In the China, the network is known as the "National Grid". We all used some transmission and distribution line insulators on electric power transmission-transmission lines, such grey glazed porcelain pin type insulator.

A wide area synchronous grid, also known as an "interconnection", directly connects a large number of generators delivering AC power with the same relative phase, to a large number of consumers.

Historically, transmission and distribution lines were owned by the same company, but starting in the 1990s, many countries have liberalized the regulation of the electricity market in ways that have led to the separation of the electricity transmission business from the distribution business.

Nowadays, transmission and distribution lines, insulators can be manufacturer in same company. Orient Power is one of pin insulator manufacturer in China, if you want to know electrical insulator knowledge, please visit Orient Power website.
