Promoted by information technology and scalable systems, optical fiber composite overhead ground wire (OPGW) can not only improve the use efficiency of power towers, but also give full play to dual role communication cable wire, due advantages high reliability, excellent mechanical performance low cost. The effective processing data from OPGW effectively promote wide application. In this paper,...

Smart Grids (SG) enable power generation, distribution, transmission, customers and utilities to transfer, predict, monitor manage energy usage effectively. In order provide them, SGs need be fully realized by integrating communication technologies infrastructures. Today, have some main systems. These are Advanced Meter Reading (AMR), distributed renewable energy, storage, electric vehicle smar...

As the most important working area of gear, teeth play the role of transmitting load and power. Tooth line and tooth profile are the two main characteristics of the tooth surface, which affect the shape of the tooth surface, tooth meshing characteristics and contact characteristics. Taking the elliptical cylinder gear pair in the reversing device of a new type of drum pumping unit as the resear...
