Submersible Pump Cable Selection and Sizing Guide

Are you looking for guidance on choosing and determining submersible pump cables? Selecting the right submersible pump cable and its size is important for submersible pumps' efficient and reliable operation. The waterproof performance of these cables is particularly critical, as they are often submerged underwater for extended periods. The choice of materials and manufacturing processes directly impacts the lifespan and cost-effectiveness of submersible pump cables. Undersized cables can compromise pump performance; therefore, making a proper selection is essential.

CKW, a renowned manufacturer of such cables and wires, will provide comprehensive information in this guide on how to select the right submersible pump cables. Let’s explore everything you need to know about these cables.

What Are Submersible Pump Cables?

Submersible pump cables connect irrigation equipment to deep well pumps for power supply. They are mostly made of copper conductors, although aluminum conductors are also used. They come with various insulation materials, including PVC, TPE, XLPE, rubber, and other hybrid materials with different structural configurations, such as single-core and multi-core. Common characteristics include flexibility, making them easier to install and use.

Their applications include sewage treatment plants, seawater handling, groundwater pumping, fire fighting, borehole drilling, water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, irrigation systems, and water supply systems.

● Differences Between Submersible Pump Cables and Submersible Pump Wires

CKW manufactures both submersible pump wire and submersible pump cable, which mainly differ in structure and shape:

Submersible pump cables come with an outer jacket for protection. This jacket is UV-resistant, so the cable itself doesn't require particularly high strength. These cables are generally round and are typically used in Japanese and European systems.

Submersible pump wires must have excellent waterproofing, UV resistance, and oxidation resistance as they are used without an outer jacket for protection. XLPE is a common material for these wires, and RHW wire from CKW meets the XLPE standards. One of the main advantages of using this wire is its lower cost.

Types of Submersible Pump Cables

Each submersible pump cable type has unique characteristics and advantages, allowing users to choose the most suitable option based on their requirements and environmental conditions.

1. Flat Submersible Pump Cable:

Flat submersible pump cables, such as those used in narrow conduits or tight spaces, are often used in applications where a compact and low-profile design is needed. These cables are commonly used when traditional round cables may not be suitable due to space constraints. Their outer insulation material is PVC or TPE, offering good abrasion resistance. Due to their unique shape, flat cables may offer advantages in specific installation scenarios, providing flexibility and ease of handling. They offer a practical solution for installations with limited space.

2. Round Submersible Pump Cable:

Round submersible pump cables feature a traditional cylindrical shape and construction, consisting of multiple insulated conductors bundled together. Their diameter is larger than typical flat cables. This is because the conductors in the cable are arranged in a circular pattern instead of parallel. However, these cables are highly flexible and easily installed in various environments. They are easier to bend and route, making them a reliable choice for powering submersible pumps in various applications.

3. Twisted Submersible Pump Cable

Consists of twisted conductors for improved durability and performance. It is suitable for typical light and medium-duty submersible pumps.

4. Armored Submersible Pump Cable:

It is enhanced with armor for added protection in rugged conditions. The armored construction provides enhanced mechanical protection against physical damage, abrasion, and crushing. Thus, these cables are suitable for harsh and demanding environments.

5 Factors to Consider When Selecting Submersible Pump Cables

Here are the details of the key factors that provide insights into making decisions when selecting submersible pump cables.

1. Motor Horsepower (Critical):

This refers to the power of the submersible pump's motor, which determines the amount of electrical current the pump will need. Select a cable that can handle the motor's power requirements for efficient and safe operation.

2. Voltage (Critical):

The cable must resist the voltage and current required for the submersible pump's operation. Choosing a cable with the correct voltage rating to prevent, electrical failures, and potential hazards.

3. Operating Environment:

When selecting submersible pump cables, consider waterproofing, chemical resistance, and durability factors. The cables should resist exposure to water, sunlight, and other environmental conditions commonly found in submerged or outdoor applications.

4. Cost:

Balancing specifications with budget considerations is important when selecting submersible pump cables. Performance requirements are crucial when selecting cables, but don't forget to consider costs and value for money.

5. Safety:

When choosing submersible pump cables, prioritize safety. Choose cables that meet safety standards and regulations, like CKW's submersible pump cables. To achieve optimal safety performance, consider insulation quality, cable construction, ampacity, and temperature rating. By considering all of these factors, you can select the right submersible pump cables for your needs, keeping optimal safety and performance.

Principles of Selecting Submersible Pump Cable Size

Selecting the right size of submersible pump cable includes several principles:

● Determine Motor Size and Current Requirements:

Start by identifying the size of the submersible pump motor and the amount of current it requires for operation. This information will help determine the appropriate wire size for the electrical load.

● Calculate Conductor Cross-Sectional Area:

Calculate the required cross-sectional area of the conductor based on the motor size and current requirements. This will guide you in selecting a cable with sufficient capacity to carry the necessary electrical current without overheating.

● Evaluate Physical Size Constraints:

Assess the physical dimensions of the installation site, including the well space, liners, and drop pipes. Choose a cable size that fits comfortably within these constraints to avoid installation issues. Ensure compliance with safety codes and guidelines to minimize risks and ensure reliable operation.
