2.2.1. real chapter¹⁾ The Rules apply to AC and DC conductors with voltage up to 35 kV. Additional requirements for conductors installed in explosive and fire hazardous areas are given, respectively, in Ch. 7.3 and 7.4. The chapter does not apply to special conductors for electrolysis installations, a short network of electrothermal installations, as well as to conductors, the device of which is determined by special rules or norms.

1. Agreed with Gosstroy of the USSR on January 28, 1977; approved by the Glavtekhupravlenie and Gosenergonadzor of the USSR Ministry of Energy on February 15, 1977. Amended by the Decision of the Main Technical Administration and Glavgosenergonadzor of the USSR Ministry of Energy E-2 / 83 of February 25, 1983

2.2.2. A current conductor is a device designed for the transmission and distribution of electricity, consisting of uninsulated or insulated conductors and related insulators, protective sheaths, branch devices, supporting and supporting structures.

2.2.3. Depending on the type of conductors, conductors are divided into flexible (when using wires) and rigid (when using rigid tires).

A prefabricated rigid current duct up to 1 kV, supplied in complete sections, is called a bus duct.

Depending on the purpose, bus ducts are divided into:

trunk lines, intended mainly for connecting distribution busbars and power distribution points, shields and individual powerful electrical receivers to them;
distribution, intended mainly for connecting electrical receivers to them;
trolley, designed to power mobile electrical receivers;
lighting designed to power lamps and electrical receivers of low power.

2.2.4. A current conductor with a voltage above 1 kV, which goes beyond the limits of one electrical installation, is called extended.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Compact version of the GeForce GTX 970 graphics card 24.10.2014

With the growing popularity of compact gaming systems with discrete graphics, the demand for small but powerful graphics cards is on the rise. Case manufacturers offer many models of Micro ATX or even Mini ITX format, but if designing a case, even a small one, is relatively simple, then creating a compact video card is a much more difficult task, because high-end accelerators surpass modern central processors in terms of power consumption and heat dissipation.

The first truly compact yet powerful video adapters began to appear after the announcement of the NVIDIA Kepler graphics architecture and the GK104 processor. The idea was especially taken to heart by ASUS, which released a series of DirectCU Mini video cards: first the GTX670-DCMOC, and then the GTX760-DCMOC. With solutions based on AMD Radeon chips, things were worse due to higher TDP, but you can still remember such a model as the MSI Radeon R9 270X Gaming ITX. Now GIGABYTE has joined in the pursuit of compactness, introducing a new GeForce GTX 970 model with a shortened base.

The new model with the GV-N970IXOC-4GD index is a full-fledged version of the GeForce GTX 970 and differs from the usual variants only in dimensions, or rather, in length - after all, creating a low-profile video card with a TDP of 145 watts is hardly possible. Although many lovers of compact systems would take this version of the GeForce GTX 970 with enthusiasm. The GV-N970IXOC-4GD's PCB is only 12 centimeters long, which means that most Mini ITX cases that accept dual-slot expansion cards will easily accept it into their guts.

The question arises, what did GIGABYTE donate when creating new items? At first glance, nothing. GV-N970IXOC-4GD even has a small factory overclock: 1076/1216 MHz against the reference 1051/1178 MHz. A single eight-pin connector with a load capacity of 150 watts is used to connect the power. The cooling system of the novelty is quite simple and, for obvious reasons, uses only one fan, but otherwise it is made according to modern canons: the copper base transfers the heat flow to the aluminum radiator through three heat pipes, two of which have a diameter of 8 millimeters.

Shortened ASUS solutions were rightly criticized for the increased noise level. It is possible that the acoustic performance of the new GIGABYTE solution will also be somewhat worse than that of traditional-sized graphics cards. But the developer company is absolutely sure about the performance of the cooling system and even gives figures: 62 degrees Celsius under load in the Metro: Last Light shooter versus 76 degrees demonstrated by the reference NVIDIA cooler under the same conditions. There are no savings on switching capabilities either: the card has two DVI ports, one of which supports only digital connection, three DisplayPort connectors and a full-size HDMI connector.

The recommended price of the novelty is $330.
