What are the functions of cables on the market?

Marine cables usually use chemical fiber ropes, which are petrochemical products. Chemical synthetic fibers such as spider silk, cotton silk, and sheets are usually woven into ropes using machines.

Depending on the material, Marine Ropes include: polyester multifilament, polypropylene filament, high molecular weight polyethylene, aramid rope, nylon monofilament composite rope, etc. Commonly used ship ropes on conventional ships are generally polypropylene filament or polyester multifilament ropes.

Marine cables can be divided into eight-strand, twelve-strand, etc. based on the production process. Eight-stranded ships are usually used on regular ships.

Boat ropes have a lifespan. This service life is usually related to the rope's material, weaving method, number of wears, usage details, etc. Typical service life is one to three years. When aging ship ropes need to be renewed, how do we choose reliable ship ropes?

Cable material combination

Boat ropes of the same thickness have varying tensile strength and abrasion resistance. The reason is the difference in materials. For example, to simply increase the tension on a rope, choose boat rope made of polypropylene filament. If you are worried about excessive wear and tear when the boat rope is hauled up on the deck, you need to braid the rope skin on the outer layer of the rope.

The rope is made of polyester to increase wear resistance, that is, the overall structure of "polyester multifilament" is added (the core is polypropylene filament responsible for strength, and the rope is very wear-resistant polyester). This method can greatly extend the rope of the boat. The service life of the product can generally be extended by twelve months.

Marine cable classification:

1. Soft, durable, moisture-proof, light weight and easy to carry.

2. It is 1/4 lighter than the white and brown rope of the same diameter, but its tensile strength is more than 3 times greater.

3. The elongation can reach 20-40%, but it cannot be restored if it exceeds 10%.

4. The softness of chemical fiber ropes decreases when used in severe cold areas.

Marine cable classification:

1. According to the twisting method: twisted rope, Braided Rope, braided rope;

2. According to chemical composition: Nylon Rope, high molecular weight polyethylene fiber rope, polyester rope, Polypropylene Rope.
