5 Common Mistakes to Avoid When Buying Submersible Power Cables

Selecting the right submersible power cable is critical for the efficiency and reliability of your operations. Avoid these common pitfalls to make an informed purchasing decision.

1. Ignoring Environmental Conditions

Submersible power cables operate in harsh environments, including oil fields, geothermal wells, and mining applications. Failing to account for factors like temperature extremes, chemical exposure, and mechanical stress can lead to premature failure. Always verify the cable's specifications match your operating conditions.

2. Overlooking Voltage Drop Calculations

Voltage drop is a critical factor in submersible applications. Undersized cables can cause significant power loss, reducing motor efficiency and increasing energy costs. Use proper voltage drop calculations to select cables with adequate conductor size for your specific installation depth and power requirements.

3. Compromising on Insulation Quality

The insulation system is the first line of defense against environmental challenges. Many buyers make the mistake of choosing cables based solely on price, sacrificing insulation quality. Look for cables with:

• High-grade EPR or XLPE insulation
• Robust jacketing materials
• Proper thickness for your application

4. Neglecting Proper Termination Methods

Even the best submersible power cable will underperform if improperly terminated. Common termination mistakes include:

5. Focusing Only on Initial Cost

While budget considerations are important, the cheapest submersible power cable often proves most expensive in the long run. Consider:

• Energy efficiency impacts
• Maintenance requirements
• Expected service life
• Downtime costs

Our independently developed submersible power cables, when paired with our permanent magnet motors, have demonstrated 25% greater energy efficiency than standard solutions. The optimized design also reduces length by nearly two-thirds compared to conventional options, offering both performance and space-saving advantages.
