PGP / ПГП – geophysical wires with PE insulation

Technical characteristics of PGP wire

  • Geophysical wires with PE insulation according to Company Standard СТ ТОО 41021646-10-2007;
  • Maximum working pressure of wire if used in stationary state from -50°С (-15 °С at assembling works) to +60°С, at relative air humidity up to 98% and temperature up to +35°С;
  • Resistivity of conducting wire is showed in the table;
  • Breaking strength is showed in the table;
  • Resistivity of insulation at 1 km length with 20°С temperature – no less than 10Mohm;
  • Testing resistivity of wire for 1 min after 10 min being underwater;
  • Factory’s length for all the PGP grades - 1000±10m.

Structure of PGP wire

  • Conducting core of PGP wire consist of corrugated galvanized steel wires according to Company;
  • Standard ТУ 14-4-1457-87 and copper wires according to State Standard ТУ 3518 РК 4043838373-ТОО-17-2003 or only of corrugated galvanized steel wire according to ТУ 14-4-1457-87;
  • Conducting core of PGP wire is insulated with PE according to Company Standard ТУ6-11-00203335-97-95;
  • Wires are twisted with optimal pitch if there are 2 or more cores;
  • There is a PE cover laid above twisted core of wires PGP3-0/7, PGP3-4/3, PGP2-0/3 according to State Standard GOST 16336-77.

Application

Geophysical wires are made to transfer adoptable voltage up to 120V with to 10kHz frequency at geophysical field works, to make field connection, as well as to transfer electrical signals from measuring devices set in vertical and slant holes, ground cracks up to 1000 meters.
