According to foreign media reports, Samsung has confirmed that the first TIzen open source system equipment will be released in 2013.
Samsung issued a statement in an interview with the media recently: "We plan to release new and competitive TIzen devices this year and will expand this product according to market conditions."
Earlier reports said that Samsung and Japan ’s largest mobile operator Docomo will jointly develop the open source smartphone operating system TIzen. DoCoMo is the only one of the three largest mobile operators in Japan that does not sell an iPhone, which has caused it to lose a lot of users in the past four years. TIzen smartphones may be released globally at the same time.
Tizen was the earliest combination of Intel MeeGo and Samsung LiMo systems, supported by the Linux Foundation. Due to the failure of both MeeGo and Samsung Bada, both facilitated the development of a new platform, Tizen, against Apple iOS and Google Android.
Yesterday, Canonical released the Ubuntu mobile operating system. This operating system will connect smartphones with desktop systems and have a wealth of gesture instructions.
Although many comments believe that in the current market, after Apple iOS and Google Android, it is difficult to appear the third popular mobile operating system, but there are many manufacturers to try in this area.
Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.
Advantages
1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
