Model comparison, operating conditions and RFQ checklist.
A submersible pump cable is a flexible power cable built to work permanently under water. It connects a submersible pump in a well, borehole, tank or flooded pit to the surface supply. It combines finely stranded tinned copper conductors, rubber insulation and a water-resistant outer sheath, and is selected by water type, immersion depth, rated voltage and flat or round shape.

What sets TEBAOFLEX Submersible Pump Cable apart in service.
Stated water depths run from 300 m for S1BNH2-F and 600 or 800 m for Drincable to 2000 m for the (N)TMH3S P2.
Drincable 600 and 800 have EPR insulation and a light blue cross-linked sheath, reference BS 6920 and are listed for water up to +80 °C.
S1BNH2-F has a halogen-free, low-smoke, flame-retardant EM2 rubber sheath, relevant where surface runs pass through buildings or tunnels.
The ELCOSUB (N)TMH3S P2 has a blue TPU sheath listed as abrasion, impact, tear and oil resistant, for groundwater and seawater service.
Flat cable needs less space beside the riser pipe and round cable seals more easily in a gland; S1BNH2-F is flat and Drincable 600 is also available flat.

Cores, earth conductors, pilot and fibre-optic elements are laid up with the fillers and screens the type designation requires.
Reinforced double-sheath constructions are extruded and cured for abrasion, oil and tear resistance.
Conductor resistance, voltage withstand and insulation resistance tests at the levels set by the referenced standard.
Bending, tensile, hot-set, ozone and flame tests according to the referenced standard.

Every batch of copper rod, rubber compound and reinforcing material is checked before it reaches the line.
Stranding, insulation extrusion, core assembly and sheathing run under recorded process parameters.
Finished lengths go through the routine tests required by the referenced VDE, ICEA, IEC or NEK standard.
Samples from production are tested for the duty a mining, crane or submersible cable will actually see.
Before packing, the cable is checked against the order and the flame-performance requirement of its standard.

For drinking water, Drincable 600 and 800 are stated for permanent immersion in potable water to 600 m or 800 m. For wells and sewage, the flat S1BNH2-F halogen-free rubber cable covers fresh and salt water to 300 m. For dewatering, deep or saline water, the (N)TMH3S P2 with a polyurethane sheath is stated for groundwater and seawater to 2000 m. The first two are rated 0.6/1 kV, the (N)TMH3S P2 0.6/2 kV.
Flat cable needs less space beside the riser pipe, while round cable seals more easily in a gland. S1BNH2-F is a flat cable, Drincable 800 is round and Drincable 600 is also available flat on request. Bending radius is specified by cable height for flat types, 3 × H up to 12 mm height and 4 × H above, and by overall diameter for round types.
Drincable 600 and 800 are designed for submersible pumps in potable water. Both have Class 5 tinned copper, EPR insulation and a light blue cross-linked sheath, reference EN 50525-2-21 (AD8) for water resistance and BS 6920 for non-metallic materials in contact with water, and are listed for water up to +80 °C. Request potable-water hygiene documents for the exact model at RFQ stage.
The ELCOSUB (N)TMH3S P2 is not for explosion-hazard areas or for water containing more than 0.5 mg/l of chlorine, and corrosive water or water of other special compositions must be checked case by case. The permissible water temperature is 60 °C; at higher water temperatures a shortened service life is to be expected. It can be used indoors, outdoors and in industrial and agricultural plant.
Confirm the stated depth first: 300 m for S1BNH2-F, 600 or 800 m for Drincable and 2000 m for (N)TMH3S P2. Compare the suspended cable weight with any listed maximum tensile load, such as 15 N/mm² for S1BNH2-F, and clamp long drops to the riser pipe. On long drops, size the cross-section for motor-start voltage drop as well as current rating.
Send the water type, temperature and chemical content; the installation depth and total cable length; motor power, supply voltage and starting method; the number of cores, cross-section and pilot cores; flat or round construction; and the required standards and documents. Request current test and certification documents for the exact model at RFQ stage, including potable-water hygiene documents where applicable.
