TMP-NTSWOEU 1.8/3-3.6/6kV Submersible Pump Cable

TMP-NTSWOEU Medium-Voltage Submersible Pump Cable

TMP-NTSWOEU is a medium-voltage submersible cable to DIN VDE 0250 Parts 812 and 813, used to connect submersible pumps and other electrical operating equipment working in industrial water. TEBAOFLEX manufactures it in two rated voltages, 1.8/3 kV and 3.6/6 kV, each with its own dimension and weight table. The two voltages are not interchangeable: the same nominal cross-section has a different outer diameter in each, so the voltage must be fixed before a gland, entry fitting or reel is selected.

The construction is organised around water ingress control. Class 5 fine stranded tinned copper conductors to DIN VDE 0295 carry the load, heat-resistant EPR compound insulates them, and a butyl rubber inner sheath of type GM1b provides particularly low water absorption and low water vapour permeability. The red outer sheath of chlorinated rubber compound 5GM3 is oil-resistant and flame retardant.

• Rated voltage: 1.8/3 kV and 3.6/6 kV, listed separately.
• Cross-sections: 3 × 25 mm² to 3 × 95 mm² in both voltages.
• Bending radius: 6 × D fixed, 10 × D mobile.
• Duty: continuous submerged operation in industrial water.

Three-core versions without a separate earth core exist, but they are only applicable where the ascending pipe serves as the earth conductor; that arrangement follows the pump installation design. For low-voltage 0.6/1 kV pump and industrial-water duty use the (N)SSHÖU heavy-duty rubber cable, and for general pump sets see the submersible pump motor cable overview.

TMP-NTSWOEU Cable Construction

The layer sequence below is the manufacturing construction for the medium-voltage TMP-NTSWOEU build. The low-voltage TMP-NSSHÖU variant uses a yellow 5GM5 outer sheath and a different table; it is not covered on this page.

Special constructions

Armoured high-voltage builds for offshore drilling rigs and for extreme submersion depths up to 1000 m are special designs made to order. They are not the standard TMP-NTSWOEU construction shown above and are quoted separately against the project drawing.

TMP-NTSWOEU Applications

TMP-NTSWOEU connects electrical operating equipment in industrial water, most commonly submersible pump motors fed at medium voltage. The cable runs submerged for the whole service period, so the selection question is not only current rating but immersion conditions, entry sealing and the earth arrangement.

• Medium-voltage submersible pump motors in mine dewatering and industrial water systems.
• Permanently submerged equipment feeds where the butyl GM1b inner sheath is required for low water absorption.
• Installations where the ascending pipe is used as the earth conductor and a three-core build without earth cores is specified.
• Rising-main installations with cable straps or clamps at the fixed bending radius of 6 × D.

Application boundaries

The 1000 m submersion depth belongs to the armoured made-to-order offshore construction and not to the standard build. State the immersion depth, water temperature and pump entry fitting with the enquiry so the correct build and termination sealing are supplied.

Related submersible and pump references

Compare NTSCGERLWOEU 3.6/6 kV submersible cable for steel-braided permanently submerged duty, (N)SSHÖU for 0.6/1 kV industrial water duty, and NTSWOEU 0.6/1 kV E-loader cable, which shares part of the designation but is a dry-duty loader cable, not a pump cable.

Reference designation cross-reference

This submersible pump cable is catalogued under its own reference name, and it is the medium-voltage half of a two-part family.

For the counterpart construction see (N)SSHÖU heavy-duty rubber cable.

For the full list of reference designations and the TEBAOFLEX build each one maps to, see the mining cable designation cross-reference.

Trademark note: TENAX®, TROMMELFLEX®, FELTOFLEX® and SCHRÄM® are trademarks of their respective owners, and TEBAOFLEX is neither affiliated with those companies nor reselling their cable. What we supply is the equivalent construction: we manufacture to the same VDE type designation and published construction, and every designation listed here can be quoted and supplied as a TEBAOFLEX build. The names appear so that an enquiry written in those terms reaches the matching construction, which is made to the standards and construction confirmed for the order.

The enquiry should state the rated voltage, cross-section and core count, pump rating and motor entry fitting, immersion depth and continuous immersion time, water temperature and chemistry, whether the ascending pipe is used as the earth conductor, drum lengths, termination sealing requirement and any project inspection or documentation scope.
