Road Cabling
The shelling of the cables is currently present in virtually any project for cable electricity supply. Particularly relevant is the spraying of pipes in the city line when roads are crossed. Given the difficult road situation of car traffic in Moscow and nearby cities, the local authorities of GHBD and the administration of the region agree on cables to be placed…
Pressure Converters
The sustainability of the tension transformers to the ferrosion has long existed, but has acquired significance only in recent years, as reflected in the introduction of the new termante-response voltage transformerin GOST 1983-2001. Normal electromagnetic TNs are not anti-response and are often damaged for this reason. In order to improve their reliability, electromagnetic…
Pressure Transformer Pattern
The one-phase voltage transducer pattern is shown in Figure. One, a. The protectors FV1 and FV2 protect the high voltage network against damage to the primary velocity of TV. FV3 and FV4 (or automatic switches) protect TV against loading injuries. Interconnection of two single-phase power transformers TV1 and TV2 into an open triangle (figure 2). Transformers are…
Measuring Instruments
A psychometric booth with self-writers - geography and thermography - a so-calledvegetation-free area- is monitored at the temperature of the soil surface and at different depths. Urgent, minimum and maximum thermometers are used to measure soil surface temperature. In winter, these thermometers are on the snow. Maximum, minimum and urgent naval thermometers (on snow…
Transformer For 12 Volts
The moderator linearly reduces the output voltage and reduces the output flow. The power source is made of aluminium hull, ventilated. Under the correct installation and conditions of use, the power supply is up to 300 to 400, hours. When selecting the power source, it is necessary to leave 20 per cent of the power supply. It is designed to connect the light-band…
Cable In The Land
Most importantly, the need to lay electrical cable in a trench on a good plot arises if street lights on the poles are to be made or an electrical connection to the bathhouse. In this case, it is very important to comply with the standards (especially SNIP and PUE) and to take into account safety equipment in electrical installation. Next, we will bring to your attention…
Electrical Production
The INVAL for nominal voltages 6(10), 20, 35 kV and currents up to 4,A are designed to operate within the distribution devices of the 3-phase AC 50 Hz with isolated or ground neutral. Cells are used in temperate areas under normal conditions. The size of the INVAL cabinet is often used where there are important savings (urban substations, power stations, industrial…
Carbon
The digitized pipes are used for the construction of power lines and low-to-point lines of the hidden type inside buildings and structures. Thanks to the flexibility of the pipe, the cabling is carried out with minimal labourers and does not require any additional accessories. The digitized pipes are manufactured at the IEK production site in Tul province. The product…
Cable Production Plants
The business is the heart of our enterprise. Work is ongoing to improve and upgrade equipment, which not only meets the required technologies and supports the quality of products at the required level, but also increases the number of products produced annually. At present, the most popular ERW and AVG power cabs are produced at the enterprise, as well as various…
Packing Of Cables
In early July, I prepared a community-centred publication on deep-sea cables, which focused on the design of deep-sea cable compared to our habitual optimism. Regrettably, very little attention has been given to the process itself and the way the cables are laid down on the bottom of rivers, seas and oceans. Now I want to rectify this situation and brief you on how…
Transformer Or Inverator
Invertible welds are now very popular and affordable. And despite their positive qualities, they, like any other electronic device, sometimes fail. In order to repair the welding machine inverter, at least a superficial knowledge of its device and its main functional units is needed. In the first two parts, TELWIN Tecnica 144-164 will be described. The third part…
Impulsive Transformator
By altering the position of the sub-constructors, the stabilization scheme manages the output voltage. Impulse Nutrition Units (PSI) Such positive developments have been widespread several decades ago and have become increasingly popular in electrical appliances by: access to a common element base; reliability in performance; possibilities to expand the working range…
Transformator
In recent years, there has been some sort of mystic and mysteriousness, knowledge that is accessible only to the elected. Part of it is, but Methodologies for the engineering calculation of transformers were developed more than half a century ago and there have been no significant changes in these years only in the use of new magnetic materials of higher quality [1]…
Transformer Serves
Rhys. 1. The diagram and the vector diagram of the voltage transformer: a - diagram, b is the vector diagram of voltage, into the vector diagram of voltage during the operation of the voltage transform without error, its primary and secondary voltages coincide with the phase as shown in the figure. 1, 6, and their ratio is Kn. In the transformation factor Kn=1 voltage…
T-3Sh Transformer
In the creation of this forcer, the aim was to make as simple as possible a design with good parameters and a decent design suitable for repetition by starters. Only the ready-to-read (network and weekend transformers, drossel) of the last centurys household bulbs are used in the assiliator. The schema of one of the powerer channels is shown in rice. 1. The input…
Pressure Measurement Instruments
A measuring instrument called Voltmeter shall be used to measure the current or EDF voltage. It is connected directly to the conclusions of the voltage source or load by means of the endurances. In the form of voltmeters, there are shooters and digitals. Different devices are used to measure constant and variable voltage. There are also universal, which can measure…
