Cable makers calling for economical manufacturing processes are clearly audible all around the world. SZ stranding along with jacketing is increasingly interesting due to it´s significant potential for savings on production, material, personnel, storage space and transport.
Famous in SZ stranding line, SZ stranding technology has also become established over the years for copper cables. The continuous call for the most economic manufacturing processes in the area of building wires and power cables made that advanced technology a growing number of significant.
The standard processes and technologies used by producers of copper cables happen to be reviewed along with the possibilities for savings happen to be analyzed. An incredibly big potential for economizing and improving the production of such cables has been introduced by SZ stranding in-line with the extrusion process.
To experience the set objectives as well as meet today’s and future requirements, various types of stranding machines as well as several ancillary units from Rosendahl Maschinen GmbH have already been developed previously being integrated into new lines as well as to upgrade existing production lines. Their higher efficiency, enhanced range of applications and uncomplicated integration have already been 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 too powerfully designed machines for achieving the market requirements involved with larger products.
As well as 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 and a special crosshead design.
Rosendahl offers the industry a very wide product spectrum of Secondary coating line created to the final product’s design.
The perfect solution from the combined SZ stranding and filling and jacketing process in just one production line meets the demand in cable production to lower intermediate production steps which lead approximately the final cable. The many combinations listed in the subsequent section provides an overview of these possibilities.
As well as the stranding of insulated conductors, Rosendahl Machinen is likewise capable to serve the best solution for stranding of single copper wires for screening applications using SZ technology. This assists our customers to have a wire screen over power cables for nearly every scale of product. An incredibly flexible stranding disc design allows coverage of a large variety of wires with no requirement to make any changes in the machine.
The gear is also ready for use for upgrading of existing sheathing lines. Alongside the wire payoffs, the product guiding unit as well as the possible copper binding unit for connection in the screening wires to have a closed cable screen, complete systems may be delivered by Rosendahl Maschinen GmbH.
One of the principal great things about SZ stranding technology is the fact that no heavy mass is rotation. The payoff and take-up stands in the line are stationary reelers that require no special foundation. The nonrotating reeler will help with boosting the line efficiency due to a extremely fast and straightforward reel loading and unloading cycle.
There is also no limitation for the size of payoff and takeup , which helps to get a long product length on bigger reels. The advantage of nonrotating machinery allows an incredibly safe working area for the operators and decreases the maintenance efforts.
The perfect combination for perfect manufacturing conditions, this equipment offering low investment costs and reduced operating costs allows for the efficient manufacturing of dexopky04 cables.
Unlimited conductor lengths and continuous operation are given with this technology, as a result of ability to splice wire ends of single conductors if dual flyer payoff units are being used. Loading and unloading can be accomplished during production, and higher production speeds lead to high stranding capacity.
Yet another main benefit from this type of gear is that SZ stranding lines could be integrated into a jacketing line in order to allow laying up and jacketing in one single production process.
One of the more important aims of cable makers around the world is to find probably the most economical and efficient processes for cable manufacturing to avoid wasting costs and also to make the most efficient possible profit. Combined SZ stranding and jacketing for building wires and power cables is unquestionably a profitable process.
Being a specialist in SZ stranding technology, Optical fiber coloring machine has recognized how the combined SZ stranding and jacketing line can effectively meet these high demands.
Also, a combined torsion blocking and powdering system placed into a location-saving dusting chamber enables uniform powdering of insulated wires and their laying up near on the torsion lock caterpillar.
Every one of these modifications and developments have triggered a total and modern production line, which meets all of today’s along with all future requirements of profitable cable manufacturing.
