Submarine Cable Polyurethane Protective Sleeve China Manufacturer

The submarine cable polyurethane protective sleeve is a protective device specially used for submarine cables. It is made of corrosion-resistant and wear-resistant polyurethane material. Its main function is to provide physical protection for submarine cables, prevent damage caused by wear, impact or biological corrosion in the marine environment, and extend the service life of the cable. Polyurethane materials have the characteristics of high strength, tear resistance and aging resistance, so that the protective sleeve still maintains excellent protection performance under the high pressure and complex environment of the deep sea. This protective sleeve is widely used in offshore wind power, transoceanic cables and other marine energy transmission projects, providing reliable guarantee for the safe and stable operation of cables.

Production process of submarine cable polyurethane protective sleeve

  ● Material preparation: Select high-quality polyurethane raw materials, including polyether or polyester polyols, isocyanates, etc., and add anti-aging agents, plasticizers and other additives as needed to ensure that the materials are wear-resistant and corrosion-resistant.

  ● Mixed ingredients: Mix the polyurethane material and additives in proportion, and after precise batching, ensure that the chemical composition of the polyurethane is stable to achieve excellent physical properties and durability.

  ● Mold design and processing: Design the mold according to the specifications of the submarine cable to ensure that the size and shape of the protective sleeve meet the requirements. The mold usually uses precision machining technology to ensure that the wall thickness and shape of the protective sleeve are uniform.

  ● Injection molding: The mixed polyurethane material is injected into the mold and molded under high temperature and high pressure conditions to ensure that the protective sleeve has a dense structure and no bubbles. After molding, it is cooled and demolded to obtain a preliminary protective sleeve product.

  ● Post-processing: The protective sleeve after molding is surface treated, trimmed and polished to ensure a smooth appearance and no burrs, and passes strict quality inspections, including size, pressure resistance and wear resistance tests, to ensure that the protective sleeve meets quality requirements.

  ● Performance testing: The finished product is tested for corrosion resistance, impact resistance, wear resistance and other performances to ensure that it has excellent protection in the marine environment.

The main advantages of submarine cable polyurethane protective sleeves

  ● It has strong resistance to seawater corrosion and can maintain structural stability for a long time in high salinity and changeable marine environments.

  ● It has high elasticity and tear resistance, can withstand external force impacts that may be encountered during submarine construction and laying, and prevent cable damage.

  ● It remains flexible at low temperatures and will not crack due to changes in seawater temperature, which is suitable for the harsh conditions of deep-sea environments.

  ● The molding and installation of polyurethane protective sleeves are relatively simple. During the manufacturing process, they can be customized into various specifications according to the cable size. They are easy to install and have strong adaptability.

  ● Non-toxic, non-polluting, have little impact on the environment, meet environmental protection requirements, and are ideal protective materials in marine engineering.
