Marine electrical cables are built to withstand the unforgiving marine environment. These durable cables protect against elemental exposure and chemical reactions in the sea environment, vessel machinery and control panels, and aquatic facilities. But some people assume that they function in the same way as general copper cables that are being sold in the market.
It’s time to debunk the myths that prevent people from investing in high-performance marine cables. Take note of these things that distinguish fact from fiction.
Myth: All electrical cables quickly corrode in marine environments.
Marine cables generally refer to all types of insulated wires that are durable enough to withstand the harsh environments in vessels and marine equipment. Marine power cables, for example, function in the same way that copper cables do. They can transmit electricity, too. But they’re more resilient.
Whereas regular copper cables corrode in marine environments, marine-grade cables are corrosion resistant. They can withstand the elements of seawater that cause most copper cables to deteriorate.
What else makes marine cables susceptible to corrosion in marine environments?
- They’re typically made from tinned copper, which has a reduced chance of oxidation.
- They contain more copper than regular cables. This increases the current-carrying ability.
- They have durable insulation that boosts cable flexibility in tight spaces and boat hulls.
So when somebody says that all electrical cables will eventually corrode, it might be true. But marine cables will take much longer to show the effects of seawater and oxygen.
They’re manufactured for circuit wiring, communications, and other applications in ships and marine facilities. This results in less wiring malfunctions for an extended period. Their resistance to corrosion and oxidation significantly reduces the cost of cable repair and replacement.
Myth: Marine power cables are large and bulky.
Marine cables are used for lighting, instrumentation, and communications in sea vessels and marine facilities. They also serve as general power wiring for ships and facilities that are regularly exposed to seawater. They’re made of tinned copper and thick insulation that prevent corrosion and oxidation. But these functions don’t necessarily mean that marine cables are physically larger than regular copper wires.
Today’s marine cables undergo thorough screening for maximum function and quality. And because these wires are most used for shipboard circuit wiring, the components are adjusted for optimal performance. The copper content is higher, and the insulation is thicker to protect against humidity, weather, and seawater. But outwardly, their diameter isn’t that much different from regular cables.
Myth: Marine cables are harmful to the sea environment.
There will always be people who assume that marine power cables contain toxic components that harm marine life. Given that sea cables are designed specifically for use in the marine environment, manufacturers try to make them as safe as possible for sea vessels and marine facilities. Whether used in boat hulls or for vessel communications, they don’t have adverse environmental effects.
