The heating wire PNSV-1,2 with a steel core and with polyvinyl chloride insulation is designed for heating monolithic concrete, and is also used in floor heaters that operate under 380 Volts of alternating current. It is also used for heating industrial facilities in the oil and gas industry. At a low temperature of concrete from 5 ° C and below, there is a need for uniform heating of concrete for better solidification. Currently, heating concrete with a heating wire is the most common. The reasons for this are the relatively low cost of the wire, the sophistication of the technology of its application. In addition, the heating wire has an undeniable advantage over heating mats - all the heat released by the wire goes directly into the concrete body. PNSV wire can be used to warm up any structures, including the floor, but most often it is used for heat treatment of floors, staircases and marches.

Main Features:

  • AC voltage up to 380 V
  • The estimated length of the wire section at a voltage of 220 V is 110 m
  • Specific heat dissipation power of the wire:for reinforced construction30-35W/p. 
  • Specific heat dissipation power of the wire:for non-reinforced construction35-40W/p.
  • Recommended supply voltage: 55-70 V
  • The average value of the resistance of the core: 0.15 ohms / m
  • Specific power: 1.5-2.5 kW/m3
  • Consumption of PNSV 1.2 mm wire: 50-60 p. m./m3 of concrete
  • Thermos holding cycle of structures: 1-3 days
