In order to conduct lightning protection at home, you need lightning, current leads and earthing. At the Lightning have a direct lightning strike, it falls on them as dynamic, and thermal load current, so they must be strong enough to match the size of the house. To protect your house is small, use Lightning as a rod made of galvanized steel, angular or round steel wire with a diameter 0.7-1 cm, gas or water pipes. In addition, the use and rods of iron or steel, which is then coated with two layers of waterproof paint. To arrange a lightning rod tube, take the tube 2 cm in diameter and flatten it with a hammer. To ensure the integrity of its current leads to the upper end is placed a plate of lead, and the lower - flat end of the current leads and the lead plate as a gasket, fastening them with screws. Lightning can be made from wire, bending it in a loop with a twist or loop fastening with a soft wire. Current leads are made of galvanized steel round wire of diameter 0.6 cm, and of flat or angled steel pipes of 5 cm in diameter, rebar, etc. Lightning hold together with the current leads by means of bolts, rivets, welding or soldering. Staples, nails or clamps used to secure current leads are attached to the walls of the house every 1.7 m. If the current leads are laid on the roof of neognestoykih materials, then attach it to a vertically positioned 20 cm wooden stakes every 55 cm Earthing is selected depending on the nature of the soil and the groundwater level. Thus, in dry soil and a low level of groundwater use grounding of the vertical type, and in wet soils and high groundwater - grounding of horizontal type. For vertical take 2.5 earths - and 3-meter long metal rods and pressed against them in the ground at 3 m from each other. At a depth of 50 cm metal rods connect the bridge cross section of 1 sq. In the middle of the bridge attached current leads. Grounding of horizontal type is made of steel wire with a diameter 1.7-2 cm and a length of 4-5 m and placed them into the ground to a depth of 75-80 cm instead of steel wire can be used flat steel or thick-walled tubes with a diameter of 3-5 cm .
