Power cable CPEM24 series

for geoelectric prospectingTPE-insulated

CABLE FOR MARINE GEOELECTRIC PROSPECTION, 24 TAKEOUTS, SPACING 2 MT Description Marine geoelectric prospection cable manufactured through flexible connectors with TPE insulation and yellow PUR sheath, characterized by high resistance to entrainment and usury. Connecting bushings are in graphite. Cables are supplied with standard military connector with bayonet, characterized by maximum strength and durability, equipped with protective caps to avoid humidity or dust accumulation during instrument transport and deployment. High quality of materials makes cables transport and connection to instrument extremely easy and in the same time grants quality of recorded data. Cables are supplied on high resistance plastic cable reel to grant strength and lightness during transport; they are equipped with stationary restraint for connector to avoid damages or cables accidental unrolling. This type of survey is based on the calculation of the resistivity from the d.d.p measurements in the ground. The method is based on the introduction of an electric field in the ground through electrodes (input or current) and the measurement of the d.d.p. in other electrodes (of measurement type). From the d.d.p. value, it will be possible to find the resistivity value through the second law of Ohm, which is a typical characteristics of all materials. Since rocks are resistive materials by nature, the resistivity variations are due almost exclusively to the presence of water in different quantities. Electric tomography 2D-3D is carried out by fixing electrode grids in the ground (16, 32, 64, 128….) at constant pitch.
