Control Cable KVVG

Brief description of kabelyKontrolny kvvg cable designed for fixed connection to electrical appliances, devices, and assemblies of clamps electrical switchgear with nominal ac voltages up to 660 V with a frequency of 100 Hz or dc voltage up to 1000 V Cables kvvg used to strip outdoors, indoors, channels, tunnels, in an aggressive environment, in the absence of threats mechanical damage. The design of the cable control cable kvvg designed to operate in a steady state at ambient temperatures from -50 C to +50 C, relative humidity up to 98% (at temperature to 35 C). In operating mode, the maximum allowable temperature for a long time of heating cable cores to + 70 C, in an emergency mode or overload – + 80 C (heating duration is not more than 8 hours per day and 1000 hours for the entire lifetime). Short-circuit (up to 4 seconds), the maximum permissible temperature of the heating wires (up to 4 sec) – + 160 C. Cables kvvg for 5 min. ac voltage withstand test of 2500 V. The insulation resistance was living at 20 C under section 0.72 – 1.5 mm2 is 10 mw / km, under a section 2,5-4 mm2 – 9 mw / km, with section 6 mm2 – 6 mw / km. Nominal thickness of insulation for core cross-section 0.75 – 2.5 mm2 – 0.6 mm, section 4 – 6 mm 2 – 0,7 mm, cross section 10 mm 2 – 0,9 mm.

Laying and installation of cables without kvvg preheating at a temperature not lower than -15 C. The minimum bend radius for cabling in diameter and 10 mm – 3 Dn in diameter from 10 mm to 25 mm – 4 Dn diameter of 25 mm – 6 Dn (Dn – outer cable diameter). Warranty period Operating cable kvvg – 3 years, life at laying in the open air and in the trenches at least 15 years old, while laying on the premises, tunnels, canals – at least 25 years. Follow others, such as Essex Financial, and add to your knowledge base. Building cable length of at least 150 m. At a single gasket kvvg cables are self-extinguishing. Scope primeneniyKontrolnye kvvg cables are intended for installation outdoors, indoors, channels, tunnels, in an aggressive environment, but in the absence of mechanical impact on cable. While ensuring protection of places of an exit to the surface of the cables kvvg can be constructed in soil (trenches).

Design Houses Settlements

Especially popular in the form of enhancing the private construction, uses the services of design houses. Principles of our work is based on constant contact with the customer to maximize the technical meeting his wishes and requirements. Design houses include a development of technical documentation – drawings and floor plans. The project developed a cottage in the light of utilities – electricity, water supply and sanitation. Designing cottage communities – a service which uses quite a lot of our customers. Enough to come to our office once to make sure that we have great weight, but our clients do not just ask us for help and trust us and respect us. The company "Stroyproekt, as a general contractor and the customer, which can be and you will always find a common denominator of successful cooperation. The same can be said about the construction of cottage settlements, because it is also one of the many services we provide.

As is known, the construction of cottage settlements often held outside the city, because today more and more people seek to escape from the bustle of the city and our company is happy to fulfill your dream. Enjoy clean and fresh air, quiet and beautiful landscape – that is what now wants every second resident of the city, which is why the construction of cottage settlements especially in demand. We know this and are ready to assist in carrying out this type of construction work. You are already slightly higher were able to find a list of all the services we provide to our customers, but we would like to assure you that it is – just strictly a schematic representation of our work, because any service – designing facades buildings or construction of industrial buildings – not only requires a serious approach.

Frame Construction Technology Cottages

The most affordable option for private traders at the moment is the frame house. Houses of this type are assembled from prefabricated elements, just as we were building a child's constructor. Exterior walls of the structure formed from individual panels and frame, usually made of solid or laminated wood. Recently, some manufacturers are offering for a private low-rise construction, metal frames, characterized by a strong and longevity, but the cheapness and ease of wooden frame houses allows them to remain popular among private owners. Framework elements combine with nails or steps and coated on both sides of sheet materials (Plasterboard) or boards. The inner space is filled with insulation panels based on mineral wool, such as plates lite batts . Interior walls, floors and ceilings are also made of framed panels insulation. Thickness of the insulation in external walls is calculated depending on the region construction.

If we use the thermal insulation based on mineral wool, the wall of a frame house at 200-250 mm thick thermal resistance can be equated to a brick wall two meters thick. Even in severe cold this house retains heat for a long time. This will reduce heating costs up to 50%, compared to the brick house. To build a frame house requires 2-3 times less wood than a log or wooden logs, respectively. The construction is roughly the same times lighter, which is important when constructing a foundation. Prefab homes can be build on the pier foundation or foundation "floating bars".

Property (or rather, build) this house is a few days. Another advantage is that the owner may at any time to increase the area home due to additional extensions. Serve such homes, subject to the quality of assembly and use of quality materials, up to 70 years, and comfort are not inferior and even superior to wooden logs and wooden buildings. Among defects of frame houses usually called the restriction of the height to 2 storeys (increased number of floors leads to considerable complication of the skeleton and reduce its reliability) and the lack of seismic resistance (up to 5 points). Kind of frame houses are panel houses, which are used to build ready-panel-boards. Panel houses require particularly careful assembly to ensure the spatial stiffness and windproof. Outside panel houses often brick veneer, providing ventilation gap between the shield and a brick wall. Most of frame and frame-panel houses built in the U.S., Canada and northern Europe – in Scandinavia. In Russia, in view of its efficiency and speed of erection of such houses are also becoming more popular.

Features Plastic Windows

In our country, where the determining factor when choosing glass house is most often the price, new windows until you have no competitors. Although they benefit from its competitors not only cost but also on expediting installation, sealing, thermal protection, unpretentious service, and often even for durability. Of course, this does not mean that new windows are deprived of their shortcomings and problems in the operation, but the benefits are so obvious that the problematic issues on this background are negligible. The more so because manufacturers are actively improve their products, gradually seeking solutions approximating new windows to the ideal method of glazing. Structurally, new windows largely inherit the scheme used in the manufacture of wooden windows. But designers have developed profiles of pvc, which became, in essence, uniform, thus the whole cycle from manufacture to installation divided between a number of specialized companies. Some of them are involved in the release of these profiles and others design and produce furniture.

Private glass shop windows produce, and companies collect garbage from this "designer" ready-made products and install them for customers. This division of the production cycle possible, on the one hand, more carefully refine the production technology at each stage, which, naturally, significantly raised the quality of the finished plastic windows, and on the other – to shift production to the conveyor, automatic and semiautomatic line, which resulted in record low production costs. In the end it turned out that most "bottleneck that determines the quality of products turned out to assembly and installation work.
