Electrical Submersible Pump (ESP) Cable Repairs 

Schlumberger RedaMAX 400 is a high voltage (HV) cable designed specifically for use with electrical submersible pumps, however the cable can also be used within gassy wells and other high temperature applications in the oil and gas industry.

The benefits associated with the RedaMAX 400 ESP submersible pump cable include lower life cycle cost, long insulation life and longer ESP system life. 

The ESP cable is available in three options including the common round option but also a flat cable version.

RedaMAX 400 ESP Cable Specifications

The three versions of the Schlumberger RedaMAX 400 cable are avalabile in different voltages :

• 4kV Flat Cable
• 4kV Round Cable 
• 5kV Flat Cable 
• 5kV Round Cable

 

3M EPDM Rubber Cold Shrink Tubes

When repairing Schlumberger RedaMAX 400 cables it is advisable to use the 3M EPDM Connector Insulators 8420 Series Cold Shrink Tube. This insulating tube forms part of the wider range of cold shrink tubes available from 3M and distributed by T&D. There are many benefits of using cold shrink technology : 

• Simple installation, requiring no tools or heat - ideal "explosive atmospheres"
• Can accommodate a wide range of cables - versatile 
• Good thermal stability and tight seal  
• Fungus, acid and alkali resistant 
• Excellent wet electrical properties for offshore installations

3M EPDM cold shrink tube forms a  cable sheath repair when it is applied around the electrical connector and the cable itself.

The insulating cold shrink tube is made from EDPM rubber containing no chlorides and six diameter sizes will cover a full range of 1000 volt cables. 

In addition to ESP cables, the 3M 8420 Series EPDM tubes can be used in other applications including dig-in and cable sheath repairs, insulation of secondary cable splices and primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000 volts.
