Technical and operational characteristics of the power cable VVGng designed to operate in a stationary state at ambient temperatures from -50 C to +50 C, relative humidity up to 98% (at 35 C). In operating mode, the maximum allowable temperature for a long time of heating cable cores to + 70 C, and in emergency mode or overload, its value can be up to + 80 C (heating duration is not more than 8 hours per day and 1000 hours for the entire period of service). Short-circuit (up to 4 seconds), the maximum allowable heating temperature lived (up to 4 sec) – + 160 C. Cables VVGng for 10 min. stand the test of alternating voltage 3 kV and 3,5 kV cable with an operating voltage of 660 V and 1000 V respectively.

The insulation resistance was living at 20 C under section up to 1,5 mm2 is 12 mw / km, under a section ,5-4, 0 mm 2 – 10 mw / km, cross section 6.0 mm2 – 9 mw / km, cross section 10-240 mm 2 – 7 Mohm / km. Insulation resistance with long-lived permissible heating temperature is not less than – 0,005 mw / km. Maximum working voltage mains cable 0.66 kV – 0.72 kV for cables 1 kV – 1,2 kV. Laying and installation of cables VVGng without preheating at a temperature not lower than -15 C. The minimum bend radius when installing single-core cables – 1910 Dn, multicore – 7,5 Dn (Dn – outer cable diameter). Building length of cables for the main sections of veins: 2,5 – 16 mm 2 – 450 m, 25 – 70 mm 2 – 300 m, 95 mm2 and above – 200 m.Garantiyny life VVGng cable – 5 years, lifetime – 30 years. Scope of the Power Cable VVGng with nominal voltage of 0.66 kV and 1 kV applied in dry and wet production areas, in special cable racks, in boxes, as well as outdoors without risk of mechanical damage during operation. For laying in soil (trenches), this kind of cable is not recommended, but it has been used successfully in places subject .Kabeli VVGng designed for vertical, inclined and horizontal lines.

Let us return to the size bath If you want a small room, you do not live at his dacha in winter and warm up, wash and rinse in the steam room, then you are quite suitable frame 3×5 or 3×4. The floors in the pair will be heavy, that is – with slits. Typically, in this case, under the floor is sloping concrete screed, which you can lay galvanized sheet. Water from beneath the floor through the sewers drains dug in nearby pit or septic tank. In the rest room floors are of course well-insulated. So when you ask the customer: do you bathe and wash going in the same room? – Not to separate – and how you will divide the three-meter?, Here after it appears that three meters for the three little rooms, you need a minimum of 4×4 frame, but the rest room, at this size, a narrow, elongated and only 8kV. meters.

Given all this, the customers, in most cases, put the 4×5 frame – and the room is quite large, and steam room with washing can be divided. Now on the floors floors insulated around the log cabin – this is especially good for winter baths. If you provide the installation of water supply system and water heater, the washer installed a shower, toilet, sink and washing machine. For example, I put it in the washing tiles, punched the drain trap, and the walls are sheathed with plastic panels. Floors in such washing can be done with electric podogrevom.Chasto The question is how can we insulate the steam room floor? – In the same humidity. Question – and from there it take? – In doubles, as soon cease to give away pairs, humidity decreases very rapidly – the laundry to dry on the shelves can be. comfortably more comfortable bath is obtained when the amount of log 6×4.

Those who bought bath 6×4, often chooses a bath with a veranda. Very often you hear: 6×4 frame, and veranda 2 meters. You begin to ask: what are you going to do on porch? – Tea. So, if you want to put a table on the veranda and around the shop, then 2 meters do not succeed, the veranda to do width of 2,5 meters. To build or not build a loft If you are planning construction attic floor, the stairs to the second floor would be good to start up from the veranda. So you divide the first and second floor of heat. Recently, some customers who want to bath with a loft, manages to convince not to do this. If the site is empty, sauna need a small, but the house even when it built – vobschem nowhere to sleep. We propose to consider the "Finnish" option – it is this: the ceiling in a bath filed "for the rafters, over a pair of washer is a normal horizontal ceiling, which puts the insulation and the top batten, is a large bed, as though loft, which you can climb a ladder to addl. If you do not want to see podstropilnye overhead beams, the rafters can rely on the log walls, and ceilings are made only on the pair with the washing for the ceiling. Bath in a bowl or cylindering Saunas are larger, usually more premises. Such baths often chopped "into the bowl, once all the partitions that have chopped gables, log porch and a much greater cost. Projects such baths can be found at "Wooden houses Denisov."

There is a persistent belief that to make a foundation for a wooden house can be an unskilled laborer and the special knowledge and experience in carrying out these works is not required. However, this opinion could lead to big problems in the future, and error correction can be very expensive. The most common mistake when the concrete is poured directly into the ground without taking into account its characteristics. Meanwhile, the use of sand bags to avoid use of seasonal heave forces and as a consequence – the deformation of foundation, it breaks and other troubles. We recommend you make concrete yourself, only if the place of construction can not drive up with concrete mixer prepared from the mortar site. Sold in the local market ingredients may be simply unsound.

Before pouring the concrete, carefully check the reliability of the formwork and its compliance with the project of the foundation. Sand cushion shall be thoroughly rammed, reinforcing cage should not come into contact with the formwork and the top of a sand cushion. For keeping the basement level of the horizon, the inner wall of the formwork can be secure restrictive rail. Be sure to fill space for vents (vents) to avoid dampness, mildew and odors. Concrete is ordered with a margin of 5-10% of the current, so both in its delivery to the mortar site to the place fills it undergoes utryaske. And do not forget to use hand-held vibrators – they are very effective and significantly improve the density of concrete.

It is not directly prohibited, but never allowed. The most lenient sentence for unauthorized alterations and alterations to flats is expressed in a written warning to the offender or fine imposed upon him (Article 142 of the Administrative Code).
