As it is not sad, our country is in many technological areas lagging behind the west. One of these trends is the use of devices, surge protection, lightning protection (lightning protection) in various industries – from strategic defense objects to the "gentle" medical equipment. To protect the equipment and user input supply of the active equipment necessary to provide special protective devices. These devices divert surges in power lines from sensitive electrical equipment on the ground. To solve this problem, we developed a variety of technologies. Today in Russia, mainly applied as follows: Spark gaps, Parallel connection of varistors, Combination of varistors and surge arresters.

However, none of them is not optimal. Consider the problems that facing traditional techniques of lightning protection (lightning protection), Spark gaps. Despite the fact that the protective device using spark gaps can withstand high current overload, this technology has some significant drawbacks. To trigger the device to a high value transmitted by the voltage (kV), resulting in damage to the equipment being protected. The intensity of the spark that occurs during conducting state, often causes interference and leads to a malfunction of nearby electrical equipment. Residual currents lead to disruptions in power and, therefore, unpredictable in the equipment. -Parallel Connection of varistors.

These protective devices used by several varistors based on metal oxide that are connected in parallel to obtain high current values overload. These varistors have low thermal stability and are easily damaged due to thermal wear. Electrical characteristics of varistors connected in parallel are not identical, which also reduces their time service. These devices are designed to use an internal fuse, tripping a safety device with strong momentum in order to avoid ignition and explosion. -The combination of spark gaps and varistors. To improve overlooked voltage spark gaps, some manufacturers use spark gaps and varistors with the trigger circuit. Although nominally these devices can withstand stronger pulses, laboratory testing and field trials have shown that difficulties arise in connection with different time response characteristics of arresters and varistors. Several years ago, was created new concept of protective devices – surge suppression module Strikesorb. These devices are successfully withstand high current overload, repeated lightning and thunder, pulsed voltage, in This performance devices remain unchanged for several years. Strikesorb modules are used in surge suppression devices Rayvoss (UPIP), which may have different configurations and provide unparalleled lightning (lightning protection) of various low voltage electrical equipment from surges. Strikesorb modules and devices UPIP Rayvoss manufactured in production and are widely used Raycap around the world. One of the objects of these devices are complete electric installation is carried out on the production of "SPIC SZMA" under license from Toshiba. Thanks to this equipment the acquaintance of "SPIC SZMA" with products Raycap and December 2006 ACNP SZMA became the official distributor in Russia Raycap. Now and in the domestic industry has the opportunity to use the products, which trust world's leading manufacturers (Siemens, Alcatel, Toshiba, Emerson and others). Expensive equipment requires a large investment, but it can very quickly be damaged in case of lack of appropriate suppression devices Pulse voltage, resulting in revenue loss and important functions. Investment decisions on the purchase Rayvoss, based on the use of technology Strikesorb, allow customers to continue to profit at the expense of business continuity equipment during operation under various adverse conditions.

Shaping of curved elements on a vibration table is possible only with flat plates with a rise of up to 115 flight, with more steep slopes may occur creep of concrete during vibration. Molding on the vibration table is typical of flow-aggregate technology. Vibrating beam is a rigid rectilinear element, sliding along the articles along the guides, mimicking its shape. In this screed is spread and seal the concrete mass. If the view of the significant slope of the products observed slipping behind concrete screeds, then to it can be attached "Plume" (sheet prigruzom hindering slipping concrete). If significant deviations products should apply strict formula. Slopes of more than 25-30 should be avoided.

Screed is the simplest form the mechanism. Because relatively low rigidity, it does not provide the precision of a given thickness of the product. Moving along the rail products in small sizes can be done manually or using hoists. Forming machines equipped vibronasadkoy or sliding vibroshtampom usually have their own mechanism of movement and lifting of the forming parts. represents two vibrators fitted molding plate, committing translational motion along the guides, mimicking the shape of the product.

The concrete mass is fed from the hopper into the space between the plates by means of conveyor-feeder. Machines with vibronasadkami for making curved panels different from those for flat plates that have an additional mechanism for vertical movement. Gliding Gliding vibroshtamp vibroshtamp is a form of plate with gently upbeat, like a sledge anterior margin. Stamp provided prigruzom and vibrators, performs translational motion along the guides, and compressing the concrete laid in front of him.
