Double twist bunching machine is mainly used for stranding multi-stranded copper wires, tinned wires, enameled wires, copper-clad aluminum wires.
Working Principle:
Various wires coming into a double twist cable bunching machine which will be in charge of assembling them into a bunch or a strand.
The phase stranding process consists of assembling some strands or cables for the construction of a multi-conductor cable. Depending on the shape of its cross section, this process can be called round stranding or sectoral stranding.
These 2 processes can be carried out either with flexible or rigid and either with bare or insulated conductors
Cable Bunching Machine Type / Structures:
High performance double twist copper cable buncher with positive driven capstans; left and right directions available.
Welded steel construction. stress free annealed heavy duty frame to achieve all requirements regarding direction, sound proofing and safety.
Double twist copper cable buncher foundation or sound proof enclosure is not necessary. Aerodynamic design with performance stranding bow, along with solid high tensile steel, makes for low friction and gentle wire path.
The Rotors are dynamically balanced.
Grease Injection bearings for main spindle.
Idler pulley capstan is slip-less gear driven to achieve a constant lay length even during acceleration and deceleration.
