Reinforced barbed tape is by far one of the most perfect physical barriers to protect the protected perimeter. Reinforced barbed tape is made from galvanized steel strip having double-edged blade and a reinforced high-carbon steel core. Reinforced barbed tape has a high and piercing and cutting properties, and also has a spring effect. Reinforced barbed tape has aesthetic appearance, has a convenience for the installation and construction, used in various structural elements for the obstacle from unwanted intrusion: the roofs, fences, fences for walls, ventilation mines, fences for construction of civil and industrial use. Reinforced barbed tape divided into four types: 1. 2.

Flat security barrier concertina. 3. Threadlike security barrier. 4. Spiny welded security barrier.

Now let us consider in detail each type, its purpose, properties and uses Spiral Safety Barrier Razor. Spiral Safety Barrier Concertina is divided into two types: simple coiled security barrier Concertina and volumetric (crossover) spiraling security barrier Concertina. Simple spiral security barrier Concertina represents a spiral of reinforced barbed tape, which is installed on the stretched wire (string) as shown above. Volumetric or spiral cross barrier Safety Razor consists of a reinforced barbed tape coils coils which are fastened by special lock so that cross-volume barrier Concertina acquires properties formidable, springy, spatial structure, see figure is located below. Flat kontsrtina security barrier. High barrage properties and numerous other advantages of the flat barrier security Concertino allow the use of this barrier to establishing effective fences around the various objects of civil, industrial and military purposes. These objects include for example: the territory of industrial and agricultural enterprises, power plants, airports, warehouses, private cottages citizens, facilities of the Ministry of Defence and army units, Interior Ministry facilities, correctional facilities, facilities of other law enforcement and special agencies. Threadlike security barrier. Filamentary barrier Security is made of reinforced barbed tape lines, which stretched between the legs form an impenetrable barrier preventing unauthorized entry into the guarded area. Flat barrier made of reinforced barbed tape. Flat barrier of reinforced barbed tape designed for the construction of effective barriers stationary type for the protection of various objects from unauthorized unauthorized access. Represent a network of reinforced barbed tape attached to one another at the intersections of the wire and placed in a rigid frame. That's probably all, it remains only to determine what you need zaschischyat, the rest to professionals. When using any article direct active link to the source perfprom.ru required!

Brief description of the power wires PPVProvod ppv, flat, with the division base in accordance with gost 6323-79, is used to stiff the installation of electrical circuits with a rated voltage of 450 V (for networks 450/750V) up to 400 Hz or dc voltage up to 1000 V. wire construction PPVProvod ppv comes with 2 or 3 annealed copper conductive strands in accordance with gost 22483-77. Single-wire conductors have a cross section of 10 mm2. Insulation is made of pvc plastic in white, gray, yellow, orange, red, pink, blue, green, brown, black, purple or yellow-green flowers. Technical and operational characteristics provodSilovoy wire sst is designed for operation at an ambient temperature of -50 C to +70 C and relative humidity to 100% (at temperatures up to +35 C).

Limiting long-term exposure temperature core heating cables in the operating mode is + 70 C. The electrical Resistance wire strands at 20 C not more than 0.01724 ohm mm2 / m, electrical insulation resistance lived at 20 C is not less than 1000 ohms / km at acceptance and delivery and no less than 10 ohms / km for the period of operation and storage . Installation of cable ppv performed at or below -15 C, minimum bending radius is 10 Dn (Dn – outer cable diameter). Building wire length ppv – not less than 100 m wires up to 10mm inclusive supplied in coils, cross over 10mm – on drums. The service life of cables under normal operating conditions is 15 years. Scope provodProvod power opv is used for distribution of electric energy in power and lighting networks for stationary and nonstationary pads indoors and outdoors. Wires are some brands allow for a hidden shim under the plaster. With single wiring ppv and flame retardant.

Wood splitter, as the name implies, is designed for chopping firewood. The following article Wood splitters called machine that performs operations trimming and splitting wood. The principle of majority machine the next. A log enters on the input conveyor belt moves it toward the side of the device. Side of the device cuts a block of wood from the logs, which falls into the gutter. Hydraulic cylinder pushes the block of wood on a knife stabbing. Block of wood is pushed into the knife and break into pieces. Exotic Wood splitters are manufactured using a different operating principle.

Will is Palax 55, which saw off first block of wood from a log, then manually set opposite end of the wedge. But the performance of these machines are much lower. There are machines that use for cross-cutting guillotine cutting off the device. But ergonomics, productivity and resource raise serious doubts. In the traditional Wood splitters crosscut is performed using a disk or a chainsaw.

Machines that use the circular saw, have better performance, do not require daily thinning saws. But are more expensive. In contrast to the Woodchopper (chopper), Wood splitters are more adapted for installation of auxiliary equipment. Ability to set different racks for feeding logs. Design Wood splitters allows the input conveyor (if not included as standard). Also very convenient to work with the machine, if it is installed conveyor. There are several different classifications Wood splitters. By type of saw machines are divided into: – Machine with bandsaw – Machines with circular saw, the maximum diameter split the wood machines are divided into: – up to 25 sentimentality – sentimentality and 35 – to 40 sentimentality – sentimentality over 40, by type of drive machines are divided into: – Drive a tractor – an electric motor drive; – Combined (tractor / motor) – Diesel; control devices machines are divided into: – Mechanical – Hydraulic. Management of Wood splitters. There are two basic types of control devices: mechanical and hydraulic. Represent a mechanical system of levers of different sizes: lift / lower saws, adjustable-length block of wood, dumping logs into the chute for the split, etc. In machines with hydraulic control levers are used instead of the convenient joystick. But this increases the price. Performance Wood splitters. Wood splitters are more productive than cleaver. And that is important, performance is more predictable. Feed rate of the input conveyor machine is constant. At the same time minimizing the impact the human factor. Assistive devices for Wood splitters. For more convenient work with Wood splitters, there are various accessories. Primarily, it feeding and storage overpass. Also worth noting is the system for cleaning and packaging of the wood. For machines powered by diesel engines operating in cold weather, reasonable fuel heater installation.
