Laying Up Machine Equipped with Pneumatic Capstan Length Metering and Auto Stop on Fault for Multi Core Cable Production and Assembly
Overview
The CLY-1250/1+4 Planetary Laying-up Machine is designed for cabling / laying-up of multi-core low and medium voltage power cables, control cables, and mining cables. It is suitable for both round and sector-shaped cores (up to 5 cores). The stranding cage is equipped with a 100% back-twist function, ensuring minimal internal stress in the laid-up cable. The entire line is controlled by a PLC + HMI touch screen with inverter-driven motors for precise lay-up pitch and synchronized line speed.
Application
Laying-up of LV/MV power cables (PVC, XLPE insulated)
Control cable and mining cable assembly (2–5 cores)
Suitable for round or pre-spiraled sector-shaped conductors
Optional non-metallic taping (polyester / mica tape) and steel wire armoring
Key Features
Planetary stranding cage (1 central + 4 side bobbins, PN1250) with full back-twist capability
S/Z stranding direction, lay-up pitch stepless adjustable via PLC (300–2500 mm)
Dual-support large bearing structure for high-speed, low-vibration operation
Electric bobbin clamping / releasing, pre-twist function for sector cores
Equipped with non-metallic wrapping head (2-pad, 500–650 rpm) & optional steel armoring
Pneumatic capstan with length metering & auto-stop on fault
Complete safety protections: overload, over-travel, guard door interlock, emergency stop
