Cable makers calling for economical manufacturing processes are clearly audible all around the world. SZ stranding along with jacketing is increasingly interesting as a result of it´s significant prospect of savings on production, material, personnel, storage area and transport.
Well known in FTTH drop cable production line , SZ stranding technology has also become established through the years for copper cables. The continuous call for the most economic manufacturing processes in the field of building wires and power cables makes that advanced technology more and more significant.
The traditional processes and technologies used by producers of copper cables are already reviewed as well as the possibilities for savings are already analyzed. An incredibly big chance for economizing and improving the production of such cables continues to be created by SZ stranding in-line together with the extrusion process.
To have the set objectives and also to meet today’s and future requirements, various types of stranding machines along with several ancillary units from Rosendahl Maschinen GmbH are already developed in past times to become integrated into new lines as well as upgrade existing production lines. Their higher efficiency, enhanced range of applications and uncomplicated integration have been the standard design aspects. This equipment includes the patent-pending, high-speed SZ stranding machines using a stretched disk accumulator driven by an elastic torsion shaft at the same time powerfully designed machines for achieving the market requirements involved with larger products.
In addition to the SZ strander, there are more key components influencing performance, efficiency and product quality. They 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 gives the industry an extremely wide product spectrum of Sheathing line built to the final product’s design.
The answer in the combined SZ stranding and filling and jacketing process in one production line meets the demand in cable production to minimize intermediate production steps which lead around the ultimate cable. The many combinations placed in the following section provides an introduction to these possibilities.
In addition to 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. It will help our customers to have a wire screen over power cables for almost every dimensions of product. A very flexible stranding disc design allows coverage of a big variety of wires with no requirement to make any changes in the machine.
The equipment is also ready to use for upgrading of existing sheathing lines. Together with the wire payoffs, the merchandise guiding unit along with the possible copper binding unit for connection of the screening wires to have a closed cable screen, complete systems could be delivered by Rosendahl Maschinen GmbH.
One of many principal great things about SZ stranding technology is the fact that no heavy mass is at rotation. The payoff and take-up stands within the line are stationary reelers that need no special foundation. The nonrotating reeler will help with boosting the line efficiency caused by a very fast and straightforward reel loading and unloading cycle.
Addititionally there is no limitation for how big payoff and takeup , which assists to acquire a long product length on bigger reels. The advantage of nonrotating machinery allows a really safe working area for your operators and lessens the maintenance efforts.
A great combination for perfect manufacturing conditions, this equipment offering low investment costs and reduced operating costs allows for the efficient creation of dexopky04 cables.
Unlimited conductor lengths and continuous operation are given with this technology, because of the capability to splice wire ends of single conductors if dual flyer payoff units are employed. Loading and unloading can be done during production, and higher production speeds cause high stranding capacity.
An extra main good thing about this sort of gear is that SZ stranding lines could be integrated into a jacketing line in order to allow laying up and jacketing in a single single production process.
Just about the most important aims of most cable makers all over the world is to find probably the most economical and efficient processes for cable manufacturing to avoid wasting costs and to make the best possible profit. Combined SZ stranding and jacketing for building wires and power cables is such a profitable process.
Being a specialist in SZ stranding technology, Optic fiber draw tower has recognized that this combined SZ stranding and jacketing line can effectively meet extremely high demands.
Also, a combined torsion blocking and powdering system put into a place-saving dusting chamber enables uniform powdering of insulated wires as well as their laying up near towards the torsion lock caterpillar.
Many of these modifications and developments have triggered a total and modern production line, which meets all today’s along with all future requirements of profitable cable manufacturing.
