The GJS series is designed for power cable insulation and sheath extrusion, covering LV to EHV power cable.
This series integrated special screw design, HNT temperature control system and synchronized electric control system, allowing the extruding speed and amount to have an increase of 50% compared to those of similar extrusion lines.
Special Screw Design
Compared with normal power cable extrusion series, the GJS series has 50% higher extrusion output due to the special screw design by HNT.
The screw for GJS series has special output flow paths designed for molten plastic to guarantee high quality of extrusion. The screw has an arc spiral structure, which provides much higher extrusion quality compared with other type of screw structures. Hotting-tube technology is adopted in the screw design, which strengthens cutting and also avoids plastic decomposition by overheating. Accordingly, the melting process is guaranteed to be even and the extrusion process can reach higher speed.
