Heated concrete with heating wires PNSV Heated concrete with the heating wire electrical contact method of concrete based on the transfer of heat from the surface of the concrete laid in concrete heating wire heated by a strong current of up to tempo. 80 C. Heat is distributed as concrete has good thermal conductivity. The maximum efficiency is achieved by using wires with a steel housing F1, 8 – 3mm. They admit drive out the load on the 1st of 80 to 160 watts, depending on the electrical resistance and the diameter of the vein.

This method allows you to heat the concrete to the required strength. Heating cables should be placed in the body of concrete, otherwise they will burn! In as a heating wire using special wire for concrete stamps PNSV-1, 2 with galvanized steel housing with a diameter of 1.2 mm in PVC insulation (perhaps use radio broadcasting wires type PTPZH-2×1, 2 with two galvanized steel wires in the insulation of crosslinked polyethylene). Electrical heating wires is carried out through step-down transformer substation type TSDZ-63 / 0.38 TSDZ-80, SPB-80, CTS TO-80/86 KTP-63/OB or who have multiple levels of low-voltage, which allows you to adjust the thermal power released when the resistive wire outside air temperature. One of the substation can be warm 20-30 m3 of concrete. Resistive wire can heat any solid structures at ambient temperature to -30 SV average heating 1m3 monolithic concrete requires 60 m mark heating wire PNSV-1, 2. Table of characteristics wires type PNSV heating wire with a steel PNSV residential and insulated with polyvinyl chloride is used to heat the monolith betona.1.
