Cable makers calling for economical manufacturing processes are clearly audible everywhere in the world. SZ stranding along with jacketing is increasingly interesting on account of it´s significant likelihood of savings on production, material, personnel, storage space and transport.
Popular in optical fiber ribbon machine, SZ stranding technology has also become established over time for copper cables. The continuous call for the most economic manufacturing processes in the area of building wires and power cables has created that advanced technology a lot more significant.
The conventional processes and technologies used by producers of copper cables have been reviewed as well as the possibilities for savings happen to be analyzed. An extremely big chance for economizing and improving the production of such cables has been introduced by SZ stranding in-line together with the extrusion process.
To get the set objectives as well as meet today’s and future requirements, various stranding machines and also several ancillary units from Rosendahl Maschinen GmbH are already developed previously to get integrated into new lines and to upgrade existing production lines. Their higher efficiency, enhanced selection of applications and uncomplicated integration are already the standard design aspects. This equipment includes the patent-pending, high-speed SZ stranding machines by using a stretched disk accumulator driven by an elastic torsion shaft at the same time powerfully designed machines for achieving the market requirements associated with larger products.
Besides the SZ strander, there are many key components influencing performance, efficiency and product quality. These are stable product feeding systems, torsion lock and jacket separators like taping or powdering systems with minimized space requirements along with a special crosshead design.
Rosendahl supplies the industry a very wide product spectrum of Secondary coating line created to the final product’s design.
The perfect solution of the combined SZ stranding and filling and jacketing process in one production line meets the demand in cable production to lower intermediate production steps that lead as much as the very last cable. The many combinations indexed in the subsequent section provides a summary of these possibilities.
Besides the stranding of insulated conductors, Rosendahl Machinen is also capable of serve the optimal solution for stranding of single copper wires for screening applications using SZ technology. This helps our customers to get a wire screen over power cables for pretty much every size of product. An incredibly flexible stranding disc design allows coverage of a large selection of wires with no reason to make any changes around the machine.
The device can also be ready for use for upgrading of existing sheathing lines. Alongside the wire payoffs, the merchandise guiding unit as well as the possible copper binding unit for connection in the screening wires to get a closed cable screen, complete systems could be delivered by Rosendahl Maschinen GmbH.
One of several principal advantages of SZ stranding technology is the fact no heavy mass is within rotation. The payoff and take-up stands in the line are stationary reelers which require no special foundation. The nonrotating reeler also helps in boosting the line efficiency because of a very fast and uncomplicated reel loading and unloading cycle.
There is also no limitation for the actual size of payoff and takeup , which assists to get a long product length on bigger reels. The main benefit of nonrotating machinery allows an incredibly safe working area to the operators and reduces the maintenance efforts.
A perfect combination for perfect manufacturing conditions, this equipment offering low investment costs and reduced operating costs allows for the efficient manufacture of dexopky04 cables.
Unlimited conductor lengths and continuous operation are given with this particular technology, because of the ability to splice wire ends of single conductors if dual flyer payoff units are being used. Loading and unloading can be carried out during production, and higher production speeds bring about high stranding capacity.
An additional main advantage of this particular tools are that SZ stranding lines may be integrated into a jacketing line to be able to allow laying up and jacketing in a single production process.
Just about the most important aims of most cable makers throughout the world is to look for one of the most economical and efficient processes for cable manufacturing in order to save costs and to make the most efficient possible profit. Combined SZ stranding and jacketing for building wires and power cables is certainly a profitable process.
As a specialist in SZ stranding technology, optical fiber ribbon machine has recognized how the combined SZ stranding and jacketing line can effectively meet extremely high demands.
Also, a combined torsion blocking and powdering system placed in a space-saving dusting chamber enables uniform powdering of insulated wires as well as their laying up near to the torsion lock caterpillar.
Many of these modifications and developments have triggered a whole and modern production line, which meets each one of today’s in addition to all future requirements of profitable cable manufacturing.
