Features
Core Advantages
⚙️
High-Speed Extrusion Capability
Extrusion line speed can reach ≥ 350 m/min, ensuring high production efficiency.
🧪
Excellent Insulation Resistance Stability
After the finished cable is aged in water at 90°C for 2 hours, the insulation resistance remains at a minimum of 10 MΩ·km. After continuous water immersion testing at 50°C for several weeks, the stabilized insulation resistance is not less than 5 MΩ·km.

Processing Guide
Recommended Processing Parameters
1
Mixing:
- Mix the A and B Component evenly, drop them into the hopper. Please use EVA masterbatch if color required(it should be dry). The material must be use up within 2 hours after unpacking.(It can’t be dried.)Avoid to bring the external water in during the process.
2
Screw Type:
- Suggest to use equal distance& unequal depth,single flight screw. Compression Ratio: 1.5±0.2
- Pay-off Speed:：Without the effect of smoothness and performance, the faster,the better.
3
Extrusion Temperature:
- YHSDG-105-A: Zone1 110±10 Zone2 120±10 Zone3 140±10 Zone4 150±10 Neck 160±10 Head 160±10
- Control the melt temperature of Insulation at 170±10℃. The extrusion temperature needs to be adjusted according to the actual situation
4
Cross-linking:
- Natural Cross-link:Temperature 15-25℃,cross-link will finished around 7days.When temperature is higher than 25℃,cross-link will finished around 3days.Water bath or Steam:Control the temperature around 60-70℃,cross-link will finished about 4hours. (the thickness of the test piece is 1mm) Full performance test,water bath (steam) 65℃, more than 8 hours, ensure the material is fully cross-linked.
