How Does an Underwater Conduit System Work?

Underwater conduit systems have numerous benefits over alternative conduit systems and operate in a unique way that allows them to be used in corrosive environments. In many cases, the underwater conduit is far more cost-effective and efficient than other systems, such as aerial or submarine cable. But how exactly does underwater conduit work? And what makes it more appealing for many projects over alternatives?

The Basics of Underwater Conduit

Generally, the conduit is metal or plastic piping containing electrical wiring. These conduit systems can be flexible or rigid depending on the material used. Conduit is used to protect electrical wiring in exposed areas such as along walls or floors. It can also be used in unfinished areas like basements, attics, and outdoors. Unlike armored cable (often known as BX or AC), many types of conduit are corrosion-resistant and can be used in damp or wet conditions. This is one of the main uses of underwater conduit systems since alternatives often cannot withstand corrosive environments. Underwater conduit must be designed to withstand significant environmental challenges to be effective.

Wiring is run through conduit rather than encased in a shell (as is the case with BX). The wiring is pulled or “fished” through the conduit casing. Conduits are designed to terminate at an electrical box (or fixed equipment that serves the same purpose). Connectors are used to fit lengths of conduit together, as well as to electrical boxes. Usually, conduit and connectors will be made from the same material. In some cases, like with plastic conduit, this does not have to be the case. Additionally, while not all conduit has grounding wire (sometimes the metal raceway is used as a ground), this is more often the case nowadays than it was before. This is because using any plastic in the raceway leaves systems ungrounded.

Underwater Conduit’s Advantages

Underwater conduit systems require no digging or suspension systems to keep them safe above or below the ground. Underwater conduit is also flexible and simple to install. These qualities significantly lower the costs of installation. Underwater conduit also has excellent compressive and impact resistance. It can also be installed year round, free of problems caused by environmental conditions. Best of all, the underwater conduit is designed to resist corrosion, even in saltwater, meaning it will outlast many other options with much shorter life spans.

FRE Composites Underwater Conduit Systems

FRE Composites offers affordable underwater conduit that conforms to trench floors, even in irregular trench profiles. FRE’s underwater duct is flexible and able to withstand depths up to 30 meters (100 feet). FRE’s underwater conduit protects cables without negatively impacting the environment or suffering from environmental factors like ice and wind. FRE underwater conduit uses secure joint couplings with Bullnose Pulling Eyes for continuous lengths to be pulled at the same time. There is also no need for expensive cofferdams. With FRE Composites underwater conduit systems, you will know you are dealing with top quality conduit at an affordable price that will last in practically any environment.
