TCu/MGT/EPR/ZH/GSWB/ZH SW4 Cable for Fixed Shipboard and Offshore Wiring

The TCu/MGT/EPR/ZH/GSWB/ZH SW4 cable is an armoured 0.6/1 kV power and control cable for fixed routes on ships and mobile or fixed offshore units. Its design combines a fire-resistant insulation system with halogen-free elastomer materials and galvanized steel wire braid protection. This makes the model relevant where a project cable schedule calls for the exact SW4 construction rather than a general-purpose industrial cable.

Use the Construction, Applications, Specifications and Standards tabs to check the supplied layer sequence, fixed-installation boundary, size range, current data and test references.

Quick Suitability Check

Suitable for: fixed shipboard and offshore power, lighting or control routes that call for this 0.6/1 kV SW4 construction.
Confirm before use: core count, conductor size, grouping, ambient temperature, voltage drop, gland or termination, route bending and the project certificate schedule.
Not intended as specified: continuous reeling, trailing, festoon, submerged or repeated-flex service. These duties require a separate cable construction review.

Selection Notes for Buyers

Size the cable from the actual installation

The supplied current ratings use a 45°C ambient-air reference. Do not select the conductor from current alone. Check route grouping, enclosure or tray conditions, permitted voltage drop, starting current, protective-device coordination and the temperature de-rating table. Use the nominal diameter and weight values to confirm tray loading, transit seals, cleats and glands.

Distinguish fixed protection from moving-duty flexibility

The galvanized steel wire braid provides mechanical protection around the bedding, but the source identifies this model for fixed wiring. A mobile offshore unit does not automatically make the cable suitable for movement. If the route bends repeatedly, runs over rollers or enters a reel, provide the movement cycle, bend diameter and speed so a moving-duty cable can be reviewed.

Check substitutions layer by layer

When replacing an existing cable, compare more than voltage and conductor size. Confirm the full marking, conductor class, mica glass tape, GP4 insulation, SB1 bedding, GSWB armour, SW4 sheath, core numbering, overall diameter and required documentation. RFOU and other offshore cables can serve different project specifications and should not be treated as direct equivalents without engineering review.

FAQ

What is TCu/MGT/EPR/ZH/GSWB/ZH SW4 cable used for?

TCu/MGT/EPR/ZH/GSWB/ZH SW4 cable is used for fixed 0.6/1 kV power, lighting and control wiring in ships and mobile or fixed offshore units where the specified construction calls for fire-resistant EPR insulation, halogen-free materials and GSWB armour.

Is this SW4 cable suitable for reeling or continuous movement?

Not on the supplied evidence. The stated application is fixed wiring. Reeling, trailing, festoon or repeated-flex routes require a separate moving-duty cable review.

What sizes and core counts are listed?

The supplied dimensions cover 2-, 3- and 4-core cables from 1.5 to 120 mm²; 5-, 7-, 12-, 19- and 27-core cables at 1.5 and 2.5 mm²; and 37-core cable at 1.5 mm².

Does the page claim Lloyd’s Register approval?

No. No TEBAOFLEX Lloyd’s certificate scope was supplied. If a classification-society approval is mandatory, include it in the RFQ so the applicable documentation can be confirmed.

What should be checked before replacing another marine cable?

Compare the complete model marking, voltage, conductor class and size, core count, insulation and sheath compounds, armour, diameter, weight, bend requirement, fire test references and project certificate schedule.
