Chuangzhan Intelligent Technology | Power Cable Insulation Extruder – Ensuring Concentricity & Quality of Cable Insulation

Chuangzhan Intelligent Technology (Guangdong) Co., Ltd. is a professional manufacturer of wire and machinery. The power cable insulation extruder serves as the core equipment that defines insulation forming quality for power cables. Engineered against power cable performance specifications, it consistently produces compliant insulation layers for low and medium voltage power cables, compatible with insulation materials including PVC, PE and LSZH.

Core Extruder Technologies (Focused on Power Cable Quality)

Power cables require insulation layers with stable concentricity, uniform wall thickness, void-free dense structure, smooth continuous surface and stress-free integrity. Our power is fully developed to meet these cable criteria, guaranteeing the electrical performance and long-term operational reliability of finished cables from the main unit itself.

Screw Plasticizing & Conveying System The screw’s L/D ratio, compression ratio and flight profile are optimized via cable forming process simulation. During extrusion, materials are conveyed steadily, melted progressively and homogenously mixed with minimal fluctuation of melt pressure. It delivers consistent insulation density to prevent local porosity and voids, maintaining stable voltage resistance of cables. Residual internal stress within insulation is reduced to mitigate cracking risks over the cable service life.
Die Head Flow Path & Pressure Balancing Technology Streamlined dead-zone-free flow path integrated with self-balancing pressure design ensures uniform velocity and pressure distribution as molten material enters the die cavity. It significantly minimizes insulation eccentricity and secures high cable concentricity. The insulation wraps the conductor with superior roundness and controllable OD variation, delivering consistent finished cable dimensions for subsequent cabling processes.
Multi-Zone Independent Closed-Loop Temperature Control System Segmented independent temperature control for barrel and die head with real-time temperature sampling and dynamic compensation. Fast thermal response and low thermal interference between zones. The insulation forming temperature window is precisely controlled to avoid local overheating or insufficient plasticization. Insulation surfaces are free of specks, scorch marks and bubbles for stable appearance and uniform electrical properties.
Drive & Extrusion Flow Closed-Loop Control High-precision main drive system maintains linear stability between extrusion throughput and line speed. Extrusion output synchronizes automatically with fluctuating conductor line speed to preserve constant insulation wall thickness. It ensures consistent outer diameter across mass production and cuts reject rates.
Intelligent Recipe Storage & Reproduction System PLC control system saves full extrusion recipes for various power cable specifications with one-click recall. Forming conditions are highly repeatable for repeated runs of the same cable type. Short changeover time between different specifications, low batch-to-batch quality deviation and easy standardized factory quality management.

Advantages of Chuangzhan Extruders (Cable Production & Quality Oriented)

✅ Main unit design driven by finished power cable requirements, prioritizing insulation concentricity, density and dimensional accuracy to meet national & international power cable standards.

✅ Rigid main frame construction resists deformation during long continuous runs. Cable quality remains stable under 24/7 non-stop production without drift.

✅ Key transmission and control components sourced from top global brands to reduce downtime and avoid mass cable scrap caused by machine vibration or unstable pressure.

✅ Customized machine selection and process matching based on customer cable specifications (conductor cross-section, insulation thickness, finished OD) to support development of various power cable ranges.

✅ Proven experience in overseas project delivery. Cable forming process support provided to help customers achieve stable mass production quickly.
