Submersible Pump Motor Cable 450/750V 0.6/1kV with Control Cores

Submersible Pump Motor Cable for Pump Power, Control and VFD Duty

TEBAOFLEX submersible pump motor cable is the main product page for wet-duty pump power cables used on submersible pump motors, mixers, mine dewatering pumps, quarry pumps, wastewater pumps and VFD-driven pump systems. It is built around the practical selection points buyers normally need to confirm: voltage rating, conductor size, outer diameter, cable-entry sleeve fit, water depth, water temperature, control-core layout and screened construction for drive systems.

The cable can be supplied as a power-only pump cable, a pump cable with integrated monitoring cores, or a screened submersible pump cable for VFD operation. For large composite SUBCAB-style layouts with fiber-optic or more complex supervision elements, use the related composite pump cable page in the Resources tab.

Submersible pump cables fail for different reasons than ordinary workshop rubber cables. The weak points are normally the cable entry seal, repeated wet handling, chemical or oil exposure, conductor insulation stress, and the routing of small auxiliary sensor cables. TF-SUB addresses these points with a wet-duty CPE sheath, rubber insulation, optional integrated monitoring cores and screened versions for VFD-driven equipment.

Cross-reference: a buyer quoting a Flygt SUBCAB composite cable for a pump with MAS 800 monitoring can compare it on the SUBCAB MAS 800 reference review before a TEBAOFLEX drawing is confirmed.

Construction

1. Power conductors: flexible copper stranded conductors sized according to motor load and voltage-drop requirements.
2. Conductor insulation: HEPR or EPR rubber insulation selected for wet-duty service and conductor temperature performance.
3. Optional control cores: integrated monitoring cores or screened pairs can be included for pump sensors, thermal monitoring or supervision systems.
4. Optional screen: screened power/control constructions are available for VFD pump drives and EMC-sensitive signal circuits.
5. Outer sheath: CPE rubber outer sheath provides the mechanical, oil, ozone and water-exposure protection required for pump installations.

Applications

• Submersible pump motors for water, wastewater and industrial process systems
• Mine and quarry dewatering pumps where abrasion, wet handling and long service runs are common
• Mixers and pump units requiring integrated sensor or monitoring cores
• VFD-driven pumps where screened cable construction is required to control electromagnetic emissions
• Industrial wet wells, pump stations and water treatment facilities

Routing a TMP designation enquiry

Part of the submersible pump enquiries for this range arrive quoting a TMP designation rather than a pump rating. The designation carries the voltage class with it, so it routes the enquiry before any sizing is done.

The sheath colour is the quickest field identifier: yellow is the low-voltage build and red is the medium-voltage one. Both share the same inner sheath of butyl rubber compound GM1b with particularly low water absorption and low water vapour permeability, which is what makes either of them a submersible construction rather than a general rubber cable, and both run −40 °C to +80 °C static and −25 °C to +80 °C flexing.

Send a low-voltage TMP enquiry to (N)SSHÖU heavy-duty rubber cable, which carries the 0.6/1 kV submersible reference build. Send a medium-voltage one to TMP-NTSWOEU submersible pump cable, where the 1.8/3 kV and 3.6/6 kV tables are kept separate because the same nominal cross-section has a different outer diameter in each.

The immersion depth, water temperature and chemistry published here are the references for the builds described on this page; a TMP designation does not carry them over.

Reference note: for enquiries marked TMP-NSSHOEU, TMP-NTSWOEU or TENAX^®-TMP, use the designation page that matches the voltage class; TEBAOFLEX is not affiliated with the trademark holder.

AWG sizes and flat construction

Enquiries written in AWG, or for a flat cable to the UL 44 and ICEA S-75-381 basis rather than the European builds on this page, are quoted from our flat submersible pump cable: three EPR 90 °C phase cores and an insulated grounding conductor under a blue CPE jacket, 600/2000 V, 6 AWG to 500 kcmil, with a full-size ground available.

Specifications

Product Range Overview

TF-SUB can be configured as a power-only pump cable, a pump cable with monitoring cores, a screened pump cable for VFD duty, or a separate control cable. Use the overview below for first-stage selection, then confirm the exact conductor size, OD, weight and bend radius from the detailed table or quotation drawing.

Dimensions and Electrical Data

The table below is arranged for size selection, cable-entry planning, weight estimation and bending-radius checks. Current capacity should be verified against the actual installation method, water temperature, grouping, duty cycle and motor-starting conditions.
