Single Mandrel Packer Penetrators

These single-piece products transmit power through a single bore. They can accommodate a vast array of cable types and sizes, and are supplied factory-moulded to downhole cable, including the MLE if required. By assembling in this way in a controlled environment, two potential weak points in the completion - the lower connector and the splice onto the MLE - are removed.

Power ratings range from 140 amps / 5 kVAC through to 250 amps / 8 kVAC, with single-phase instrument feedthroughs also available. Most penetrators are fitted to the packer by way of an adapter. To accommodate for an excess or shortfall in MLE length, adapters can be supplied to allow from 3.5” to 24” of adjustment to penetrator positioning. A variety of universal thread types and offset adapters ensure a configuration to suit every completion.

RMSpumptools also produce breakaway penetrators for use in offshore drill stem testing. These products are designed to maintain the pressure integrity of the well in the event of rapid departure of the workover rig.
