Main features:
  • Any number of electrodes (24, 32, 48…)
  • Any geometry
  • Waterproof
  • Longitudinal sealing
  • Cable sheath reinforced with Kevlar

Multi-purpose  waterproof  multi-electrode  cable  systems  are designed  for  the  electrical  resistivity  tomography  surveys.  Waterproofness  of  the  cable  systems  allows  to use  them  not  only  for  land  surveys in  all-weather  conditions  but  also for surveys  on  water  areas, “waterland” transition zones and boreholes' investigations.

The cable cover is made of high-quality polyurethane with high resistance to abrasion, frost resistance and flexibility.  Copper  tubes  with  diameter  of  15  mm  are  used  as  electrodes  in  the  cable  system.  It  is  very convenient  to  attach  to  such  electrodes  a  connector  “cable  system  –external  electrode”  with  “alligator”  or RPT  -21 clips. There is  no  need  to  use external  electrodes  when surveying  on  water areas  and  boreholes, because the surface area of electrodes in cable systems has low contact resistance in such conditions.

Different  amount  of  electrodes  can  be  designed  at  the  cable  system  on  demand  (24/32/48),  as  well  as different  electrode  spacing  and  passive  ending  of  required  length.  A  standard  high-quality  connector manufactured by Amphenol can be installed at one or both ends of the cable system. Connectors for cable systems  are  compatible  with  the  CommDD2  switch  hardware  and  all-in-one  resistivity  systems  (f.e. SYSCAL/Siber).

Additionally titanium electrode-pins in bag-quivers with connectors “cable system –  external electrode” can be  supplied.  Use  of  titanium  alloy  electrodes  improves  the  electrical  resistivity  survey  performance  in remote areas, along with works on frozen or rocky ground.
