Cable heads are used for connecting wireline with perforating guns and logging tools.
NKP-1-65M Perforating Gun Cable Head with a Protective Contact
NKP-1-65M perforating gun cable head is a standard cable head for KPOXXK.326 safety pattern firing head. Specific feature of the cable head is that the contact between a cable head and a firing head is closed only under hydrostatic pressure, i.e. only at the well depth with pressure of 6 atm, thus, protecting a perforating gun from accidental actuation at the well mouth.
