> Source policy: prefer a product page and its linked datasheet over category summaries, articles, or application examples. Standards are project references and do not by themselves establish certification. Price, stock, MOQ, lead time, final ratings, compliance, and installation suitability require written confirmation for the ordered construction.

## Key features

### Motor and cable matched

Review voltage, current, starting method, conductor size and the full route from supply to pump.

### Defined immersion duty

Select insulation and sheath against the actual fluid, temperature, depth and duration of immersion.

### Installation fit

Confirm core layout, round or flat profile, cable-entry dimensions, joints and support before ordering.

### Project-specific supply

Specify cut lengths, identification, packing and required documents for each pump. Every finished cable length undergoes 100% continuity testing before shipment. A technical quotation is provided within 24 hours after receipt of a complete RFQ.


## Key specifications

| Property | Value |
| --- | --- |
| Application | Boreholes, deep wells, irrigation, drainage, wastewater and water transfer |
| Conductor | Copper; cross-section and stranding confirmed for the electrical load and route |
| Core layout | Power and protective-earth requirements follow the pump wiring diagram |
| Profile | Round or flat, subject to the pump entry and installation constraints |
| Insulation and sheath | Selected for voltage, fluid, temperature and immersion duty; oil resistance requires a defined exposure |
| Depth and temperature | Confirmed for the ordered construction; no universal immersion rating |
| Identification and packing | Project-specific colour, printing and lengths; coils, reels or wooden drums |
| Documentation | Confirm datasheet, applicable standards, tests and any required potable-water approval before production |

## Choose the cable by pump duty

DEV CABLE supplies custom power cable for pumps in boreholes, deep wells, reservoirs, irrigation, drainage, sewage and industrial water-transfer systems. This is a configurable cable family, not a single stock construction with one depth or temperature rating.

For oilfield downhole service, use the [ESP cable specification](/products/esp-cables/). Water-pump and oilfield cables should not be substituted solely because both feed a submerged motor.

## Match the fluid and immersion conditions

Clean water, wastewater, oil-contaminated fluid and drinking water require different material and documentation reviews. State the fluid composition, cleaning agents, temperature, maximum depth and whether immersion is continuous or intermittent.

“Waterproof” or “oil-resistant” alone does not establish a permitted depth, chemical compatibility or potable-water approval. Those limits must be confirmed for the cable, joint and pump entry in the actual installation.

## Construction and quotation checklist

| Selection item | Information to provide |
|---|---|
| Pump duty | Borehole, irrigation, sewage, drainage or industrial transfer; pump manufacturer and model |
| Electrical load | Voltage, phase, frequency, current or motor power, starting method and allowable voltage drop |
| Route | Total supply-to-motor length, submerged length, maximum depth and installation method |
| Copper conductors | Cross-section in mm² or AWG, stranding and required flexibility |
| Core arrangement | Power conductors, protective earth and any separate monitoring circuits; wiring diagram |
| Insulation and sheath | Fluid composition, oil or chemical exposure, temperature and immersion duration |
| Mechanical fit | Round or flat profile, available diameter, cable gland, joint, bend and support requirements |
| Identification and packing | Colour, printing, cut lengths, quantity, coils/reels/drums and destination |
| Evidence | Required datasheet, standard, inspection/test documents and potable-water approval where applicable |

If temperature, leakage or other sensor circuits share the cable, review the [pump cable with control cores](/products/submersible-pump-cable-with-control-cores/) against the manufacturer's wiring diagram.

## Size for the complete installation

Cable length is not the same as pump depth: include the route between the supply or control panel and the wellhead, as well as the drop to the motor. Conductor selection must account for current, voltage drop, starting conditions, temperature and installation method. Pump power alone is not enough to select a size.

Confirm the entry dimensions, submerged joint and cable support with the pump supplier. Do not use the power cable to carry the pump's weight unless the complete system is specifically designed for that duty. A replacement must match the entry and termination as well as the conductor size.

## Standards, testing and documents

State the cable standard, pump specification and country-specific project requirements. A generic cable designation is not proof of certification or drinking-water suitability. Any required approval must cover the ordered construction and intended use.

Every finished cable length undergoes **100% continuity testing before shipment**. Specify additional electrical, immersion, material or inspection requirements in the RFQ; continuity testing does not establish those results.

## Request a project quotation

Send the checklist above with a pump datasheet, wiring diagram or existing cable specification. Identify any unknown inputs so that they can be resolved before the construction is agreed. Include quantity, packing, destination and the required delivery schedule; delivery feasibility is confirmed separately.

DEV CABLE provides a **technical quotation within 24 hours after receiving a complete RFQ**. Use the inquiry button to start with an editable pump-cable checklist.

## Buyer questions

### Is H07RN-F automatically suitable for continuous submersion?

No. Check the specific cable's documented immersion conditions, fluid compatibility, depth and temperature. A family name alone is not approval for the installation.

### Can one cable serve both clean-water and sewage pumps?

Only when its confirmed construction covers both duties. Wastewater may introduce oils, chemicals or cleaning agents that were not part of the clean-water specification.

### Can this cable be used in drinking water?

Only after any required potable-water approval is verified for the ordered variant and destination. Water resistance alone is insufficient.

### Can the length, core count and sheath be customized?

Yes, these are reviewed with the pump data, entry dimensions, electrical load and medium. The agreed specification defines materials, marking, packing and required documents before production.

## Supplier review points

- Reliable for Continuous Submersion: Moisture-resistant insulation and jacket materials help submersible pump cables maintain reliable power transmission during long-term operation underwater.
- Built for Deep Borehole Installations: Flexible conductors and durable cable construction make installation easier in deep wells and help withstand pulling, bending, and vertical cable runs.
- Suitable for Wastewater Pump Environments: For sewage and wastewater applications, cable materials can be selected for improved resistance to water, abrasion, oils, and common chemicals encountered around pumping systems.
- Stable Power over Long Cable Runs: Correct conductor sizing helps reduce voltage drop and overheating when powering submersible pumps installed far below the surface or away from the control panel.
- Flat, Round & Custom Pump Cable Options: Submersible pump cables can be customized with flat or round constructions, different conductor sizes, core counts, jacket materials, and optional control cores to match specific pump systems.
