CANTILEVER HIGH SPEED SINGLE TWISTING MACHINE
1. Key Functional Components
| No. | Unit | Description |
|---|---|---|
| 1 | Single Twist Rotor (Cantilever Head) | Supports the bobbin and provides the rotating motion (through belt or direct drive). Rotor runs at high speed with dynamic balance. |
| 2 | Pay-off Unit | Feeds the insulated conductors. May include tension control and dancer systems for smooth feeding. |
| 3 | Twist Section | Conductors are twisted at defined pitch (lay length), with options for back-twist or non-back-twist. |
| 4 | Compaction or Filling Unit (optional) | Applies fillers or taping around the twisted core. |
| 5 | Taping Unit (optional) | For applying Mylar, mica, non-woven, or water-blocking tapes. |
| 6 | Capstan / Haul-off | Provides synchronized pulling force; ensures accurate pitch control. |
| 7 | Take-up Reel & Traverse System | Rewinds the finished cable onto reels (630–1250 mm typical size), with smooth and programmable layering. |
| 8 | PLC Control Panel + HMI | Centralized control for speed, pitch, tension, alarm, diagnostics, and length counter. |
