Engineered for High-Performance Cable Production
Our integrated system combines closed-loop pneumatic conveying with ultra-precise additive dosing (±0.1% accuracy) specifically for XLPE, EPR, and HVDC cable compounds. The solution ensures contamination-free processing of sensitive materials like cross-linking agents, voltage stabilizers, and nano-fillers while meeting 500kV+ cable production standards.
System Highlights
1. Clean Material Conveying
- Dedicated Lines for:
Base resins (LDPE/XLPE)
Carbon black masterbatch
Voltage stabilizers (e.g., Dicumyl Peroxide)
- Gentle Transport Modes:
Dense phase: <0.01% additive degradation
Anti-static design: Prevents carbon black agglomeration
2. Pharmaceutical-Grade Dosing
- Micro-Dosing Modules:
0.1-50kg/hr with ±0.1% accuracy
Loss-in-weight feeders for critical additives
- Contamination Prevention:
Stainless steel contact surfaces
Nitrogen purging for oxygen-sensitive compounds
