Cable makers calling for economical manufacturing processes are clearly audible everywhere in the world. SZ stranding combined with jacketing is increasingly interesting as a result of it´s significant possibility of savings on production, material, personnel, storage space and transport.
Famous in optical fiber ribbon machine, SZ stranding technologies have also become established throughout the years for copper cables. The continuous call for the most economic manufacturing processes in building wires and power cables made that advanced technology a lot more significant.
The typical processes and technologies employed by producers of copper cables are already reviewed and the possibilities for savings happen to be analyzed. A really big chance for economizing and improving producing such cables is introduced by SZ stranding in-line with all the extrusion process.
To experience the set objectives as well as to meet today’s and future requirements, various stranding machines in addition to several ancillary units from Rosendahl Maschinen GmbH are already developed in past times to get integrated into new lines and to upgrade existing production lines. Their higher efficiency, enhanced selection of applications and uncomplicated integration happen to be the basic design aspects. This equipment includes the patent-pending, high-speed SZ stranding machines having a stretched disk accumulator driven by an elastic torsion shaft too powerfully designed machines for achieving the market requirements involved with larger products.
Along with the SZ strander, there are other key components influencing performance, efficiency and product quality. These are typically stable product feeding systems, torsion lock and jacket separators like taping or powdering systems with minimized space requirements and a special crosshead design.
Rosendahl gives the industry an extremely wide product spectrum of Secondary coating line designed to the very last product’s design.
The answer from the combined SZ stranding and filling and jacketing process within a production line meets the demand in cable production to reduce intermediate production steps that lead up to the ultimate cable. The numerous combinations indexed in these section provides an overview of these possibilities.
Along with the stranding of insulated conductors, Rosendahl Machinen can also be capable of serve the optimal solution for stranding of single copper wires for screening applications using SZ technology. It will help our customers to have a wire screen over power cables for almost every measurements of product. An extremely flexible stranding disc design allows coverage of a big array of wires with no reason to make any changes on the machine.
The device can also be ready to be used for upgrading of existing sheathing lines. With the wire payoffs, this product guiding unit as well as the possible copper binding unit for connection in the screening wires to get a closed cable screen, complete systems may be delivered by Rosendahl Maschinen GmbH.
One of many principal advantages of SZ stranding technology is no heavy mass is rotation. The payoff and take-up stands in the line are stationary reelers which require no special foundation. The nonrotating reeler will help with boosting the line efficiency as a result of really quick and easy reel loading and unloading cycle.
There is also no limitation for the dimensions of payoff and takeup , that helps to obtain a long product length on bigger reels. The main advantage of nonrotating machinery allows a really safe working area for that operators and decreases the maintenance efforts.
An ideal 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 provided using this technology, due to capacity to splice wire ends of single conductors if dual flyer payoff units are used. Loading and unloading can be done during production, and better production speeds bring about high stranding capacity.
Yet another main benefit from this type of tools are that SZ stranding lines could be integrated into a jacketing line to be able to allow laying up and jacketing in one single production process.
Just about the most important aims of most cable makers across the world is to locate the most economical and efficient processes for cable manufacturing in order to save costs and also to get the best possible profit. Combined SZ stranding and jacketing for building wires and power cables is unquestionably a profitable process.
Like a specialist in SZ stranding technology, FTTH cable production line has recognized that the combined SZ stranding and jacketing line can effectively meet these high demands.
Also, a combined torsion blocking and powdering system placed in a space-saving dusting chamber enables uniform powdering of insulated wires in addition to their laying up near for the torsion lock caterpillar.
Many of these modifications and developments have triggered a whole and modern production line, which meets all of today’s along with all future requirements of profitable cable manufacturing.
