These are Halogen-free cables made up of:

Conductor: Copper with a coating of tin (Purity 99.7%)

Insulator: Cross-linked XLPE/ Polyethylene/HF/PVC

Sheath: Thermoplastic polypropylene or PVC

In the marine environment, cables are exposed to a lot of moisture, which will cause the copper to corrode.

Tin is most suitable for the marine environment because it has great resistance against water, which will prevent oxidation hence, corrosion of copper.

2. What Are the Advantages of Marine Grade Cables?

Marine Grade Cables have advantages over other cables because it is far tougher than other cables.

Made with top-notch quality material, it offers:

Longevity and durability as it is made with ideal material that makes it tough.

Marine-grade cables are electrical cables that offer a lot of flexibility.

This property makes it easier for it to survive the marine motions.

As it is made up of copper, it provides a high level of conductivity.

Copper has a half-filled orbital, which makes it the most stable element.

Its stability makes it better than the other elements.

The copper is coated with tin as tin protects it from oxidation and eventually corrosion.

Tin is ideally suitable for the marine environment as it has properties to resist water and moisture.

7. Why Is Marine Grade Cable Tinned?

Marine Grade Cable uses copper as a conductor to provide the highest flow of current.

It has a maximum number of fast-moving electrons that run very smoothly.

But due to moisture or contact with water, copper tends to lose its electrons.

This is called oxidation.

As it oxidizes, it will fall prey to rusting and corrosion.

This will affect its conductivity.

In order to protect the copper from corroding away, it is coated with a layer of tin through electroplating.

Tin is a savior for copper as it can survive in a hot and humid environment or withstand any kind of climate change.

The best property of copper is its resistance against water and moisture.

This way, it acts as a shield for copper and protects it from corroding away or rusting.

The tinning of copper makes marine cables different from regular cable and makes it better.

  • Copper: Copper is considered the best conductor. It provides an excellent flow of current that no other element can. Its stability gives it an edge over the other elements. It provides smooth and fast slowing current to the equipment without any hazardous damage.
  • Tin: Copper is resistant to fire and flame but not to water. It cannot survive moisture as contact with water will cause its oxidation, and it will slowly corrode away. To protect it from oxidizing, Tin is plated over copper through a process called electroplating.

These cable connectors are attached to the ends of the wire through crimping.

When these cable connectors seal the cable, they are connected to the battery.
