Black Resistance to Electricity Mark PE compound

ⅰ、Type and application

Type	Product	Application
NDGJ-01	Black Weatherability and Resistance to Electricity Mark HDPE Insulating Compound for Aerial Cables	Applied to less than 10KV aerical cables as insulation which has the requirements of resistance to electricity mark.
NDPE-22	Black Resistance to Electricity Mark PE Jacket Compound	Applied to ADSS fiber cables as jacket which has the requirements of resistance to electricity mark.

ⅱ、NDPE is a black and resistance to electricity mark PE jacketcompound special for ADSS cables, which based on PE polymer. NDPE has specialadditive. It has very good performance of resistance to electricity mark, andexcellent electrical properties, weatherability, tenacity, abrasive resistanceand excellent resistance to environmental stress crack. Meeting DL/T 788-2001standard.

ⅲ、Processing

The NDPE compound suits to process with extruder which L/D is 25 orabove 25. And it should be dried before using, the temperature is 90℃.

the following temperature(℃) profile of extruder is recommended:

Zone	1 Zone	2 Zone	3 Zone	4 Zone	Head	Die
Temperature	185	215	220	240	245	250

Note: The processing parameters are for reference only, optimalconditions may vary according to the equipment used. The cooling water tankshould be used sectionally cooling with warm-water echelon in order to reduceinternal stress.

ⅳ、Storage andtransport

Packaging：25kg/bag， PE membrane inside bag and Kraft outside bag.

Storage and transport: Avoiding in direct sunlight and weathering.The storage place should be in clean, cool, dry, and ventilated conditions.

Q: Can olive nets be used to protect against sunburn damage?: No, olive nets are typically used to protect olive trees from pests or to collect the olives during harvest. They are not designed to protect against sunburn damage to human skin.

Q: Can olive nets be used in high-density olive orchards?: Yes, olive nets can be used in high-density olive orchards. Olive nets are commonly used in olive orchards to protect the trees from birds and other pests while allowing sunlight to reach the fruits. In high-density orchards, where the trees are planted closer together, olive nets can still be effectively utilized to protect the entire orchard and maintain the quality of the olive crop.

Q: Can olive nets be customized for specific olive grove sizes?: Yes, olive nets can be customized for specific olive grove sizes. Olive nets are available in various dimensions and can be tailored to fit the specific requirements of different olive grove sizes, ensuring effective coverage and protection of the olive trees.

Q: Are olive nets flame retardant?: No, olive nets are not typically flame retardant.

Q: How can a plastic foam be used?: If you have a plaid or a unique plastic foam package, you can dye it and fix it on the wall to make it an abstract decoration. It is economical, affordable and creative. I believe it is absolutely unique! If the lattice space space, can also receive some lighter some items, such as scarves, neckties, neckties, thin gloves, hairpin, headwear and so on, readily available small objects.

Q: Can olive nets be used for other types of fruit trees?: No, olive nets are specifically designed for use with olive trees and may not be suitable for other types of fruit trees due to differences in tree size, shape, and fruit characteristics. It is recommended to use nets specifically designed for the particular type of fruit tree to ensure proper coverage and protection.

Q: How do olive nets prevent olives from being damaged by rain?: Olive nets prevent olives from being damaged by rain by creating a protective barrier that shields the fruit from the impact of water droplets. The nets are placed over the olive trees, forming a canopy-like structure that keeps the rainwater from directly hitting the olives. This helps to prevent bruising, splitting, and waterlogging, which can compromise the quality and yield of the olives. Additionally, the nets also act as a shield against hail and other adverse weather conditions, providing further protection to the fruit.

Q: Do olive nets affect the yield of the olive trees?: Yes, olive nets can significantly affect the yield of olive trees. These nets are commonly used to protect the olives from birds and other pests, reducing damage and loss of the crop. By preventing the olives from being eaten or knocked off the trees, olive nets help maintain a higher yield and ensure a better harvest.

Q: Are olive nets suitable for organic olive orchards?: Yes, olive nets are suitable for organic olive orchards. Olive nets are commonly used in organic farming practices to protect olives from pests and birds without the use of harmful chemicals or pesticides. They provide an effective and environmentally friendly solution for maintaining the integrity and quality of organic olive crops.

Q: Can olive nets be used for both small and large-scale olive oil production?: Yes, olive nets can be used for both small and large-scale olive oil production. Olive nets are commonly used in the olive industry to collect olives efficiently during the harvesting process. They can be used in small-scale operations where olives are hand-picked and in large-scale operations where mechanical harvesters are employed. The nets help prevent olives from falling to the ground, reducing potential damage and contamination. Overall, olive nets are versatile tools that can be effectively utilized in various olive oil production settings.
