KSK-1 Mendeleevets - Sliding-contact coil
Application area
A sliding-contact coil KSK-1 Mendeleevets is designed for electrometric measurements and land surveying. It is used as the extender at consecutive measurements without twisting of a cable.
Technical details
The body of the coil with a sliding contact is made of a dielectric plastic. The rotation of the drum spool relative to the base is performed by two rolling bearings. Input terminal contact with a wound cable is carried out via a sliding contact consisting of graphite brush and copper shaft of the contact. To reduce the delay and providing the possibility to lock the unwinding of the cable during transportation, the coil is equipped with brake mechanism.
For convenience of carrying the coil can be equipped with anatomic back frame. Anatomic back frame can be made in two versions: regular (ST-1, Fig. 1a), which is used only for carrying coils of KSK-1, or universal (ST-2M, Fig. 1b), intended for sharing with the KSK-1 and coil with one-time enamel wire. The coil can be equipped with the following types of geophysical cables: GUSP-141, GUSP-142 in.
