NSSHOU / (N)SSHÖU O/J, 3E and 3E + ST 0.6/1 kV Heavy-Duty Rubber Cable

NSSHOU Cable: (N)SSHÖU O/J, 3E and 3E + ST

NSSHOU is the keyboard spelling of NSSHÖU, also written NSSHOEU: the German VDE designation for a 0.6/1 kV rubber flexible cable built for special mechanical load. TEBAOFLEX supplies it as (N)SSHÖU, a construction with reference to DIN VDE 0250-812.

(N)SSHÖU is a 0.6/1 kV heavy-duty flexible rubber cable family for drilling, tunneling, mining and industrial power routes exposed to high mechanical stress. The O/J, 3E and 3E + ST versions do different jobs: the order must state whether the circuit needs standard power cores (O/J), a protective earth split into three earth cores or into a screen on each power core (3E), or screened power cores plus control conductors (3E + ST). The documented family uses Class 5 tinned-copper conductors, 3GI3 insulation, GM1b bedding and a yellow 5GM5 outer sheath.

The designation reads letter by letter:

• N – built to a VDE type; (N) – with reference to VDE
• SSH – special mechanical load
• Ö – oil-resistant sheath
• U – flame-resistant
• -J / -O – with / without a green-yellow protective earth core
• /3E – protective earth split into three parts, as earth cores or as a screen around each power core
• ST – control conductors

Every position of the code is explained in our guide to reading a VDE cable designation.

• Use when: the complete flexible power construction matches the route, grounding and environmental duty.
• Confirm first: variant, core count, conductor area, screens, control conductors, bend mode, water exposure and documents.
• Choose another family when: the circuit specifically requires monitored lighting, VFD output or a high-tensile mining reel.

NSSHÖU or NSHTÖU? Choosing the Right Rubber Cable

(N)SSHÖU is built for dragged, trailing and fixed heavy-duty routes and for submersible duty to 100 m. It has no strength member for motorized reeling: for cable drums and festoon systems, choose NSHTOU / (N)SHTÖU reeling cable, built with reference to DIN VDE 0250-814.

The maximum pulling force is 15 N/mm² multiplied by the power-conductor cross-section; split earth conductors, screens and control cores do not count. NSSHOU 3 × 95 + 3 × 50/3E therefore allows 285 × 15 = 4,275 N, the value given in the Specifications tab.

Frequently asked questions

(N)SSHÖU Cable Construction

The family construction changes with O/J, 3E and 3E + ST. Select the row by the required earth-screen and control functions rather than treating the suffixes as interchangeable.

Variant map

• O/J: standard power-core arrangement for the selected conductor identification.
• 3E with three earth cores: the protective earth is split into three earth cores between the power cores; the published range runs from 3 × 50 + 3 × 25/3E to 3 × 240 + 3 × 120/3E.
• 3E with individual core screens: a copper-wire screen surrounds each power core; the published range runs from 3 × 2.5 + 3 × 2.5/3E to 3 × 185 + 3 × 95/3E.
• 3E + ST: individually screened power cores with additional control-conductor functions; the published power-core size range is 2.5 to 185 mm².

(N)SSHÖU Applications and Boundaries

• Heavy-duty drilling and tunneling equipment power connections.
• Mining and industrial routes requiring flexible rubber cable under high mechanical stress.
• Dynamic or static power supply in dry, damp or wet environments when the exact variant is approved for the route.
• Fresh, salt, oily or sewage-contaminated water duty up to the documented 100 m reference, subject to the final construction and termination system.

Related mining duties

Use (N)SSHCGEWÖU for monitored lighting, (N)SSHCOEU for screened VFD output, or NSSHCGEOEU for the documented high-tensile guided/reeling duty. None is an automatic substitute.

RFQ data

Provide the marking, O/J or 3E/3E + ST variant, voltage, load, core count, conductor area, screen and control functions, cable length, movement, bend radius, water and chemical exposure, terminations, quantity and required inspection documents.

Reference designation cross-reference

The submersible reference build of this designation is catalogued under its own name at low voltage.

For the counterpart construction see TMP-NTSWOEU submersible pump cable.

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.

NSSHOU Current-Carrying Capacity

Current ratings at 30 °C ambient. The reeled columns apply when the cable stays wound in 1 to 7 energized layers, for example on a portable cable reel; NSSHÖU is not built for motorized reeling duty.

TMP submersible reference build of this designation

This designation is also issued as a submersible build for industrial water, to DIN VDE 0250 Parts 812 and 813. What separates it from a general heavy-duty rubber cable is the inner sheath: a butyl rubber compound of type GM1b chosen for particularly low water absorption and low water vapour permeability. The application is the connection of electrical operating equipment in industrial water, most commonly submersible pumps.

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.

Earth arrangement on a rising main

Three-core builds without a separate earth core exist in this family, and they apply only where the ascending pipe itself serves as the earth conductor. That arrangement has to match the pump installation and the local project rules, so state whether the rising main is bonded as the earth path when ordering a three-core build.

Reference size table, low-voltage submersible build

These are reference figures for the TMP-NSSHOEU submersible build, including the four-core and reduced-earth configurations that a pump set with separate control or earth requirements needs.

What is not claimed here

No immersion depth is published for this build. The 1000 m figure that appears in the reference literature belongs to a made-to-order armoured high-voltage construction for offshore drilling rigs, not to the standard build. State the immersion depth, the continuous immersion time, the water temperature and chemistry, and the pump entry fitting with the enquiry, and the correct build and termination sealing will be quoted against them.

For the medium-voltage submersible build at 1.8/3 kV and 3.6/6 kV see TMP-NTSWOEU submersible pump cable. For general pump-set selection across voltages see the submersible pump motor cable overview.

Reference note: for enquiries marked TMP-NSSHOEU or TENAX-TMP at low voltage, TEBAOFLEX manufactures to the (N)SSHÖU designation and the construction shown, and is not affiliated with the trademark holder.
