Steel reels for wire and cable

Coil contract

In-line cable insertion Unicor GmbH has developed new corrugators for quick and easy inline production of protective pipes for PEX, ALU-PEX-pipes and protective pipes for cables. The UC 58/90 (V) and UC 58/120 (V) are Unicor‘s solutions for pipe-in-pipe production and cable insertion within pipes from 8mm inside diameter and up to 58mm outside diameter. The in-line production of pipe-in-pipe or the direct insertion of electric wire into corrugated pipe saves a cost-intensive step in the production process. By integrating the final fabrication into the production cycle additional handling costs are saved. The technology is also available with the medium-sized corrugators UC 75 and UC 100. Steel maker Celsa Atlantic, of the Celsa Group, has awarded a $5million contract for a second compactor and coil handling extension to Siemens VAI, in order to increase productivity and improve product quality – an expansion of the existing system. Celsa Atlantic expects delivery in the first quarter of 2009. The coil handling extension includes a combination vertical and horizontal system and a second compactor, and provides increased on-line coil storage as well as an increase in surge capacity. The greater cooling times will enable Celsa Atlantic to produce higher quality products, such as thermomechanically treated ribbed rebar for concrete reinforcement, at its plant in La Coruña, Spain. The contract with Morgan Construction, the US based specialist of Siemens VAI for high speed wire rod mills, also includes a reloading station that can route coils back into the system for offline processing.

A Appiani Srl is an ISO 9001:2000 worldwide manufacturer and supplier of steel reels for the cable and wire industry. In recent years the company has been offering specifically designed reels to suit those applications where speed, geometrical precision and good dynamic balancing are essential, such as drawing of copper and aluminium wire. The spools are manufactured according to either internationally recognised standards or to the user’s specific requirements. Appiani’s portfolio for process reels includes solid flange machined reels type BPE, double-wall partially machined reels type BPS and double-wall partially machined reels for heavy-duty type BTC. All reels are dynamically balanced according to Q16 ISO 1940, process speed up to 40m/s. Both balancing and machining are necessary to yield a smooth rotation at high speed without

Consumables in fibreglass and thermoplastic Isolmax specialises in manufacturing in thermoplastic materials and fibreglass but can also work in other materials including Teflon, nylon, lexan, PVC, glass epoxy or polyester glass, depending on the customer’s application.

Especially for copper wire drawing machines, Isolmax produces flanges for coils and plates for annealing furnaces made from a thermosetting material. This fibreglass material is believed to be more durable and to offer higher performance than thermoplastic, which is currently used by most manufacturers of copper wire drawing machines.

The cost of material, its excellent heat resistance, mechanical properties and dielectric strength make this product successful in many other applications. The company also produces other components in fibreglass and thermoplastic material for other applications such as driving chains, tubes, pulleys, plates, bushes and pipes to individual specifications. A technical department is always available to offer advice and to find innovative solutions to customer needs.
