Types of Tests

The Opticenergo Testing Center conducts a full range of tests on cable products:

1. Inspection of design and structural dimensions.
2. Electrical parameters:
   • resistance of conductors and insulation;
   • voltage testing up to 200 kV;
   • current testing;
   • thermomechanical loads.
3. Mechanical parameters (including at elevated and reduced temperatures):
   • tensile load;
   • mechanical strength (tensile strength);
   • bending and repeated bending;
   • axial twisting and impact;
   • crushing forces;
   • galloping and aeolian vibration;
   • elongation;
   • vibration strength and vibration resistance.
4. Various environmental effects:
   • resistance to high and low temperatures;
   • resistance to humidity and rain;
   • oil resistance and petrol resistance;
   • resistance to chemical environments;
   • ozone resistance;
   • corrosion resistance (salt fog);
   • resistance to seawater.
5. Fire tests:
   • flame propagation prevention during single cable installation;
   • flame propagation prevention during bundled cable installation;
   • determination of fire resistance rating;
   • smoke generation during burning and smoldering;
   • determination of halogen acid gas emissions;
   • determination of the acidity of emitted gases (pH and specific conductivity).
6. Unique tests:
   • tracking resistance of self-supporting optical cable;
   • resistance of overhead line conductor coatings to ice formation.
