In As tokonositelya quickly spread use of aluminum, because of its cost and a more attractive relationship between weight and electrical conductivity. Finally, finally widely widely used self-supporting insulated wires mark 'Torsade', produced by the plant 'Kubler De Lance', which carries a wire made of aluminum alloy heat strengthened 'almelek', has a section 54.6 or 70 square millimeters and are always isolated, because by French standards, is a zero-current-carrying wire carrier, although it is grounded at several points. Development overhead with insulated wires in the Nordic countries has pushed the need to reduce the effects of damage caused by severe climatic conditions in the region. At the same time there is a need more than narrow paths of power lines, especially in dense urban areas. Development of a suspended cable, twisted AMKA began in 1958 in Finland, the company NOKIA KABEL as a system of wires suspended overhead low voltage. The system is rolled carrying around a bare neutral conductor phase insulated conductors, insulation which is made of thermoplastic polyethylene. Have been developed in parallel with the wire cross-linked polyethylene AHKA brand, as well as system AMKA-T AHKA-T – with insulated cable in tropical regions with high humidity. Currently the system is equipped with AMKA 170 km of VL-0, 4 kV in Finland (80%). The system also AMKA used in more than 30 countries such parts of the world like South America, Africa, Asia, the Middle and Far East: in Peru – in 1981, Saudi Arabia – since 1984, Nepal – since 1986, in the mountainous regions of the Himalayas – 1989.

Today there are numerous natural and artificial abrasives, but the first one, which mankind uses from time immemorial, is a gem. It was with him began a long history of grinding, which is inextricably connected with the history of technological progress. At the moment, practically none of the industries is not without sanding. Therefore overestimate the importance of this process, simply nevozmozhno.Shlifovanie – business fine grinding – this is a complicated process, which allows to process hard and brittle surface with abrasive materials. Today there are numerous natural and artificial abrasives, but the first of them, which mankind uses from time immemorial, is a gem. It was with him began a long history of grinding, which is inextricably linked with the history of technological progress.

At the moment, virtually no one of the industry is not without sanding. Therefore overestimate the importance of this process is impossible. Firmly entrenched in the various branches of modern industry, grinding process gradually became available and in everyday life, enabling users to make various repairs and finishing work. Now in the arsenal of a repair of a variety of special tools for grinding, to facilitate trud.Vidy grinding tools. Grinding tools are divided into groups, bands or machines. Depending on the type of work using one or another kind of tools. Grinding wheel – it's consumable material used for abrasive machining and grinding surfaces of stone, wood and metal, it can be used as a manual or on floor looms. Grinding wheel is made of abrasive material and special bundles which may, for example, ceramic, bakelite or vulkanitovoy.Shlifovalny range of vitrified bonded has a broad scope, increased efficiency and durability.

Antivirus Packages

Our computers, namely, the Internet often are faced with various threats and dangers. If you use your computer to a network (LAN or WAN), it must be protected. More information about the general protection principles can be found in the 'Tools protect your PC and its maximum security. " The problem of protecting your PC from malicious programs are sharp as ever. Features numerous 'defensive' products from reputable manufacturers are quite varied, often they are called Internet Security. Now more and more developers are now part of the protective package the backup utility (for automatic backup at connection of a removable drive to your computer, archiving, data protection with their passwords and etc.), but even the most powerful suite of software oboroitelnogo completely guarantee the security of data can not. You may wish to learn more. If so, Uber is the place to go. The main component of computer security – is, without doubt, a good antivirus program. But the cost of anti-Professional-versions of software packages are not always affordable for the average user.

One of the most popular and successful free antivirus Avira AntiVir Personal 8.1 can compete with commercial products but its functionality. Program deals not only with catching viruses and trojans trying to get into your system, but with scanning files and folders, check mail SMTR traffic, and keeping track of malware (keyloggers, dangerous scripts on web sites, rootkits, and macro viruses). In AntiVir uses heuristic analysis, there ability to work from the command line – a full set. Adjustment of various parameters is performed as a simple (a few basic options), and in expert mode, allowing more subtle to pick up one or another security settings and scan. Built-in scheduler allows you to run a scan while the computer is idle. Update the virus database is maintained. The disadvantage of this utility are: lack of function for checking incoming e-mail (checks only the outbound traffic). Avira Personal AntiVig little inferior to what is paid counterparts – a huge database of viruses (150 thousand), high speed and adequate response to known and unknown viruses.

Marine Power Plants

The main means of increasing capacity and efficiency of marine diesel power plant is turbocharged. Submission of the additional amount of air cylinders and, correspondingly, increase supply Fuel duty cycle, resulting in an increase in power a diesel power plant. Pressure diesel exhaust is 1.5-2 times higher than that of a gasoline engine that allows you to turbocharger provide boost and avoid inherent in gasoline engines with turbo failure – 'turboyamy'. In many diesel engines installed cooler nadduvaemogo air. These structural measures help to raise mass filling the cylinders and much, sometimes several times, to increase capacity.

Turbocharging improves combustion and reduces the hardness of work and loss of power. However, a diesel power plant with turbo has some disadvantages, mainly related to the reliability of the turbocharger. Resource turbo diesel engine is much smaller resource and usually does not exceed fifteen thousand hours. The turbine has high requirements for the quality of lubricating oil. Faulty turbine can totally disable the engine.

And his own life forced the engine slightly lower than the same air of diesel. The fuel system equipment Common-Rail – a modern solution to engine building. In each section a diesel engine high pressure pump pumps the fuel into the "separate" fuel line (going to a particular nozzle). The tubes are thick enough. In this case, when the high pressure 130-270 kg / cm on it "is run" portion of the fuel TTVD swells like boa, swallow prey. And once it goes into the fuel injector TTVD again compressed. This leads to the fact that after a specified portion fuel injector to necessarily "pumped" a tiny extra dose. This fuel, burning, increases fuel consumption, increases the opacity of the motor. Themselves as separate pipeline pulsation increased noise of the engine. C increasing the speed of rotation (rpm) modern automotive diesel engines (up to 4000-5000 r / min, (including marine diesel power plants) it has to deliver tangible inconvenience. A number of firms over time Engineers have found a solution to this problem for high-speed diesel engines. According to this scheme, fuel pump delivers fuel to the total pipeline – fuel rail, a kind of receiver. This middle tier is placed a constant volume of fuel which is under constant pressure – 1,300 bar. Nozzle opening is no longer fluid mechanics method (increase of pressure in the pipeline), and electronic – from a signal supplied to the solenoid injector. At its based computer assigns the right to operate the motor fuel and the time of its filing. Thus, the "snake" is not frantically pushes through the esophagus, "food", and operates in strict accordance with decisions taken by its computer. For marine diesel power unit – ignition engine fuel compression – it is very important, as the pressure in the combustion chamber increases more smoothly, without a "breakthrough." Therefore, ship diesel works less noisy. But most importantly – a system of Common-Rail eliminates injection into the combustion chamber "dosylnoy" portion of the fuel. Such designs of fuel injectors for engines made possible only in our time, this contributes to the development of electronics.
