1. Applications and cable specifications of LLHDPE granule:
Insulation of aerial cable, less than 1KV.
 
2. Description of LLDPE granule:
PE compound, based on PE resin, is produced and pelletized with the double corrugated screw, in which various additives are added. The compound is according to GB 15065-94 and IEC 60502. The compound has outstanding performances of processing, physical, mechanical and electrical properties.

3. Processing of LLDPE granule:
It is recommended that compound should be processed with extruder having a minimum L/D ratio of 25. Compound (not including ZPE) should be thoroughly dried before use,  and the maximum drying temperature should not exceed 100°C.
The following temperature(°C) profile of extruder is recommended:
 

Note: The processing parameters are for reference only, optimal conditions may vary according to the equipment used. The cooling water tank should be used sectionally cooling with warm-water echelon in order to reduce internal stress.
