## Key features

### Power and Monitoring in One Cable

Motor power, protective earth and the required sensor or control circuits can be combined in one project-specific underwater cable.

### Designed Around the Pump

Core layout, conductor sizes, materials, overall diameter and cable-entry constraints are reviewed against the supplied pump data.

### Sensor-Circuit Options

Additional cores can be arranged for thermal switches, PTC, PT100, leakage, moisture and other pump-monitoring circuits.

### Optional Signal Screening

Twisted or screened control pairs and individual or overall screening are optional, depending on the cable design and monitoring system.

Industrial submersible pumps may need more than a standard motor power lead. Temperature switches, PTC or PT100 sensors, bearing-temperature devices, leakage electrodes and moisture detectors each need conductors between the submerged pump and the monitoring equipment. This product combines the required motor power conductors, protective earth and sensor or control cores in **one custom underwater pump cable**.

Unlike a standard stocked H07RN-F, H07RN8-F, flat pump cable or basic 3-core/4-core pump cable, this is normally engineered to a customer-supplied pump specification. The final construction must follow the pump manufacturer's wiring diagram and the electrical, dimensional and environmental requirements of the installation.

## Built Around Your Pump Configuration

This product is produced to specification rather than offered as one fixed warehouse configuration. A buyer can define the number and size of power cores, the protective-earth conductor, the number and size of control cores, twisted or screened pairs, individual or overall shielding, cable length, cable outer diameter, jacket material and marking.

The review also considers operating temperature, immersion depth, exposure to water, sewage, oil or chemicals, the cable-gland size and the pump cable-entry dimensions. Materials and layers are selected only after these inputs are known. Custom cable configurations can be manufactured according to customer-supplied pump specifications, wiring diagrams and cable-entry dimensions, subject to engineering confirmation.

## Typical Construction

### Conductor

Flexible stranded bare copper or tinned copper can be considered. The conductor material, class and cross-section are confirmed for the final cable design.

### Power Core Insulation

EPR, HEPR, EPDM or another insulation may be selected according to the electrical rating and operating conditions. The material is configurable; no one insulation applies to every construction.

### Control / Sensor Cores

Flexible copper conductors with individually identified insulation can be included for pump monitoring. Core identification and circuit assignment must match the approved wiring documentation.

### Optional Control Pair

A twisted pair or screened twisted pair can be incorporated for monitoring signals when required by the pump system. This layer is optional and depends on cable design.

### Protective Earth

A dedicated PE conductor can be included according to the pump's electrical configuration and applicable project requirements.

### Screening

Copper braid, copper tape, individually screened control pairs or overall screening may be considered where additional EMC control is required. Screening is optional, and its construction and termination must be agreed for the specific system.

### Inner Filling / Bedding

Water-resistant elastomeric filling or bedding may be used to support the required roundness and internal arrangement. It is optional and depends on cable design.

### Outer Sheath

A heavy-duty elastomer, CPE, rubber or another customized compound may be selected for continuous or prolonged submerged operation. Suitability for the actual water, sewage, oil or chemical exposure must be confirmed for the final compound.

## Typical Custom Configurations

| Example Configuration | Typical Use |
|---|---|
| 4G2.5 + 2×1.0 mm² | Small industrial pump with temperature or leakage monitoring |
| 4G4 + 2×1.5 mm² | Pump motor plus two sensor circuits |
| 4G6 + 2×1.5 mm² | Medium-power wastewater pump |
| 4G10 + 2×1.5 mm² | Industrial sewage or drainage pump |
| 4G10 + S(2×0.5 mm²) | Pump with a screened monitoring pair |
| 4G16 + S(2×0.5 mm²) | Higher-power pump with a screened sensor pair |
| 4G25 + 4×1.0 mm² | Customized pump-monitoring configuration |
| Custom | Built according to the pump wiring diagram |

The configurations above are examples only. Final conductor sizes, control-core arrangement, insulation, sheath, screening and cable diameter are engineered according to the customer's pump and installation requirements. They are not presented as certified standard sizes or as stocked configurations.

## What Are the Control Cores Used For?

### Motor Temperature Sensors

Additional conductors can connect thermal switches, PTC devices or other winding-temperature monitoring devices to the external pump-monitoring system.

### Bearing Temperature Sensors

Larger industrial pumps may monitor bearing temperature. Dedicated signal cores can be allocated when the pump wiring diagram requires them.

### Leakage / Moisture Sensors

Control cores can carry signals from water-ingress, seal-failure, leakage or moisture detection devices installed in the pump.

### PT100 / Temperature Sensors

Dedicated conductors, and where required a suitable pair arrangement, can connect PT100 or other temperature sensors used for more precise measurement.

### Pump Monitoring Systems

Signal conductors can link the pump's installed sensors to external monitoring or protection equipment. The actual circuit design, conductor assignment, screening and termination must follow the pump manufacturer's wiring diagram and monitoring-system requirements.

## Standard Pump Cable vs. Pump Cable with Control Cores

| Standard Pump Cable | Cable with Control Cores |
|---|---|
| Primarily supplies motor power | Supplies motor power and monitoring circuits |
| Usually uses a standard core configuration | Uses a custom power-plus-signal configuration |
| Commonly selected as a stock item | Typically manufactured to project requirements |
| A separate control cable may be needed | Control or sensor cores can be integrated |
| Limited sensor integration | PTC, PT100, leakage and temperature circuits can be accommodated |
| Usually has a standard OD | OD can be engineered around cable-entry constraints |

Buyers who only need a conventional power lead should review our [Submersible Pump Cables](/products/submersible-pump-cables/) page. This integrated product is intended for pumps whose monitoring circuits or cable-entry constraints make a standard power-only construction unsuitable.

## FAQ

### Can power and sensor conductors be combined in one submersible pump cable?

Yes. The cable can be designed with motor power conductors plus additional control or sensor cores according to the pump wiring configuration and subject to engineering confirmation.

### Can you manufacture screened sensor pairs inside the pump cable?

Screened or twisted sensor/control pairs can be incorporated when required by the pump monitoring system. The screen type and termination arrangement must be confirmed for the application.

### Can you produce 4G10 + 2×1.5 mm²?

This type of configuration can be evaluated for manufacture according to the required insulation, sheath, overall diameter, cable entry and operating environment. Final feasibility is confirmed during the specification review.

### Can the cable include PTC or PT100 signal conductors?

Dedicated signal cores can be included for PTC, PT100, thermal switches, leakage sensors or other pump-monitoring circuits. Their number, size, identification and pair arrangement must follow the wiring design.

### Can you match an existing pump cable?

DEV CABLE can evaluate replacement requirements from cable markings, dimensional drawings, wiring diagrams, conductor sizes, materials and cable-entry limitations. A match or equivalence is confirmed only after technical review.

### Can you customize the cable outer diameter?

The cable structure can be optimized around cable-entry and gland limitations, subject to conductor size, insulation thickness, screening, electrical requirements and manufacturability.

Every finished cable or cord length undergoes 100% continuity testing before shipment.
