The product uses polypropylene as the matrix resin, adding other polyolefin resin, antioxidants and processing aids etc. for mixing and modification. It is used as 35kV and below extruded insulated power cable insulation material, with excellent dielectric properties, mechanical properties, high&low temperature resistance properties and excellent processing performance. It is an environmentally friendly thermoplastic cable insulation material.
Property:
The typical values in the table come from the type test report issued by the National Cable Testing Center.
Processing:
1. It can be used in the conventional production of 35kV and below power cable CCV catenary production line equipment extrusion, no need for crosslinking and degassing. The extruder should meet the maximum temperature control not less than250 ℃, to meet the polypropylene extrusion manufacturing.
Extrusion temperature setting
It is recommended to use a three-layer filter (40-80-40); Before and after production, the extruder should be cleaned.
1. It is recommended to use a single-thread equidistant varied deep screw extruder with a screw length-diameter ratio of 25:1 and a screw compression ratio of about 2 for production, together with the use of special shielding products for polypropylene insulation.
The recommended extrusion processing temperature is as below:
-Above temperature is only for reference. It is recommended that customers adjust according to the current at the time of extrusion, the melting pressure and the actual situation after the cable extrusion.
Product packing
600kgs, moisture-proof, sunscreen. (corrugated carton packaging, with sealed film bag inside)
Note:
1. 1.Before use, it is necessary to confirm that the sealed packaging is intact. The product should not be exposed to air for a long time.
2. 2.Transportation, stacking and storage should prevent sun, rain and water immersion, etc.and the storage environment should be clean, dry and ventilated.
