5 key considerations for choosing the right submersible cable

Diving into the world of submersible cables can be overwhelming when you have a vast array of options to choose from. That’s why selecting the right cable is always crucial for success. With so many factors to consider, it's easy to get lost in a sea of technical jargon and confusing specifications. Fear not! In this blog post, we'll guide you through the 5 key considerations that will help you make an informed decision when choosing the right submersible cable for your needs.

Important factors for selecting the right submersible cable:


    • Conductor area: The conductor is the wire that carries the electrical current, and its size or area can have a significant impact on the cable's performance. In general, the larger the conductor area is, the lower the resistance of the cable will be. A lower-resistance cable can handle higher currents without overheating or losing power. Additionally, a cable with a larger conductor area will have a higher capacity for power transmission, allowing it to deliver power over longer distances without significant power loss.


    • Sheathing: The sheathing of a submersible cable is a vital component that provides protection to the cable and its conductors from the harsh underwater environment. It acts as a barrier against water, chemicals, and other elements that can potentially damage the cable, leading to equipment failure or safety hazards. A submersible cable's sheathing plays a critical role in maintaining the cable's electrical properties and preventing current leakage. Water or other liquids can seep into the cable if the sheathing is damaged, which can cause a short circuit, resulting in equipment damage or failure.


    • Insulation: The insulation material used in submersible cables must be carefully selected to ensure optimal performance and durability in harsh underwater environments. The insulation must be able to withstand high pressures, extreme temperatures, and exposure to seawater, salt, and other corrosive substances. It's essential to choose the right insulation material that can withstand the specific conditions of the application to ensure safe and reliable operation.


    • Conductor: The conductor's material and quality can affect the cable's electrical resistance, current-carrying capacity, and overall performance. Copper is the most common conductor material for submersible cables due to its high conductivity, corrosion resistance, and durability. However, some applications may require other materials, such as aluminium or speciality alloys. Poor-quality conductors can cause signal degradation, electrical interference, or even equipment failure. High-quality conductors can maintain optimal electrical performance and reliability, even in harsh underwater environments.


    • Voltage: Choosing the right voltage rating for a submersible cable is crucial to ensure safe and reliable operation. If the voltage rating is too low, the cable may fail or overheat, leading to equipment damage, power loss, or even fire hazards. On the other hand, if the voltage rating is too high, it can cause insulation breakdown, electrical arcing, and other electrical hazards. Moreover, the voltage rating of a submersible cable can affect its electrical performance, especially over long distances or high-current applications. A higher voltage rating can help to minimize power loss and maintain optimal electrical transmission, resulting in better equipment performance and energy efficiency.
