LD Jacketing Compound (Cable Cover)
LD jacketing compound, particularly black bimodal linear low-density polyethylene (LLDPE), is a high-performance material used primarily in the jacketing of energy and communication cables. The formulation of the compound provides excellent abrasion resistance along with a low coefficient of friction, making it ideal for use in different types of cables, especially those subjected to harsh environments or with high mechanical performance.
The MFI of the compound is tested at 190°C under a load of 5 kg. The value is 3 grams/10 minutes (1133). This MFI range makes it suitable for extrusion as well as the manufacturing process and also provides black color that gives UV resistance, which is necessary for cables that have exposure to sunlight or are outside for a long time.
Properties of LD Jacketing Compound
The LD jacketing compound offers a balance of properties that provide several advantages throughout the lifecycle of energy and communication cables
Abrasion Resistance: The compound is highly resistant to abrasion, meaning it can withstand rough handling, installation, and environmental factors like sharp edges or rough surfaces, which helps extend the lifespan of the cables
Low Coefficient of Friction: This feature allows easier installation with less damage of the jacketing during the pulling process. It also works as an anti-sticking and anti-binding factor in case cables are installed across large distances or within confined areas.
UV and Weather Resistance: This compound has black color not just as aesthetic, but provides an enhancement in UV resistance. Outdoor-installed or sunlight-exposed cables must have UV protection against degradation; hence this jacketing material gives great resistance to that type of environmental degradation. It is weather resistant; thus it withstands the changes in temperature and other severe conditions of weather with moisture
Thermal Stability: The LD jacketing compound has good thermal stability. This means that when exposed to normal operating temperatures, the insulation of the cable will not undergo deterioration over time. This is highly important in energy and communication cables, which may experience temperature changes during operation.
Chemical Resistance: The polymer exhibits resistance to some chemical bases and acids, therefore appropriate for industrial applications where cables would be exposed to oils, solvents, or chemicals.
Flexible and Durable: Being rigid, the material has maintained flexibility to some extent; that is critical for installing cables under trying conditions. It enables flexibility for bending and maneuvering to allow the cables without cracking on the jacketing, that is perfect for underground complex installations.
Applications of LD Jacketing Compound
The major use of LD jacketing compound is in the energy and communication cable industries. This helps in protecting the cables from outer factors and improves the performance of the cables
Energy Cables: For energy cables, the jacketing plays a very significant role in keeping the integrity of the cable during its operational lifetime. It gives mechanical protection and does not interfere much with the conductivity of the cable
Communication Cables: The abrasion resistance and low friction characteristics help reduce wear during installation in communication cables laid over long distances. This is particularly important for cables running in underground ducts or confined spaces
Manufacturing and Performance Benefits:
The LD jacketing compound offers several advantages to manufacturers
Efficient Processing:
The compound's MFI ensures easy and consistent extrudability through the cable production process and maintains uniform jacketing.
Improved Performance of Cable:
Its abrasion, flexibility, and weather resistance enable the cables to perform satisfactorily even under harsh conditions and thus contribute to a longer service life and less maintenance or replacement.
In conclusion, the LD jacketing compound is a high-performance material tailored for energy and communication cables. Its balanced properties of abrasion resistance, low friction, and UV protection make it an ideal solution for various cable applications, ensuring reliability and durability throughout the lifecycle of the cable
