MARKET TREND—Trolley Wire for high-speed train applications is moving to Cu-Mg Wire

Copper Magnesium is a preferred alloyed-copper for high speed rail applications in many countries, as it provides good electrical conductivity and high tensile strength and good creep resistance. Additionally copper magnesium is also an enviromentally benign material with NO toxicity hazard.

From the manufacturing point of view, there is not a big difference in the drawing process, but the main difficulty of making trolley wire with Copper-Magnesium alloy is to be identified in the production of the rod for the following reasons:
1. The light and volatile nature of Magnesium
2. Magnesium’s propensity to form slag when molten
3. The need to maintain a very precise alloy composition in the wire rod
Copper-Magnesium trolley wire is now widely used in Western Europe, including on the high-speed TGV line from Brussels into France, Netherlands, Germany and Spain.

With off-shore drilling dominating the news, Cortinovis delivers large Planetary Stranders for assembling Subsea Umbilical Cables

A Subsea Umbilical Cable is a cable which supplies required consumables to oil platforms such as the ones located in the Gulf of Mexico or the North Sea. Subsea Umbilicals are deployed on the ocean floor to supply necessary control, power, and chemicals to the subsea oil and gas wells.

These armored umbilicals have breaking strengths in excess of 200 tons. They incorporate many different types of constructions and metallic sheaths and steel or synthetic strength members.

Cortinovis has developed and installed large Planetary Stranders for assembling the various cable designs required for these applications. Some constructions include members that require minimum bending requirements and are required to be abrasion resistant.

This Cortinovis machine can hold 24 main bobbins (3000 mm diameter) and 20 filler bobbins (1650 mm diameter).

The maximum weight of each main bobbin is 30 tons and the filler bobbins are 3 ton maximum. The operating speed is 15 RPM with a maximum linear speed of 45 meters per minute. This machine can handle an umbilical up to 500 mm in diameter. Other sizes and configurations are available to meet specific customer and cable requirements.

The Eurolls Group, which includes Eurolls SpA, Cortinovis Machinery, Teurema, Team Meccanica, Vitari, Corbellini, and Sictra has better than expected results from Wire & Tube 2010 Show Dusseldorf, Germany.

Mr. Andrea Camparada, Managing Director Cortinovis Machinery SpA & Sictra SrL

“We were very pleased with the turnout at the 2010 Dusseldorf Wire Show. I have personally attended all shows since the mid 1980’s, and in my opinion, this show far exceeded those in the past. Not only did we witness an increase in participation compared to years past, but customers came prepared to discuss and close actual projects and visitors, who have not attended since the 2008 crisis, were eager to reengage and discuss potential business. The Eurolls Group focuses on technical specialization which takes advantage of the core competencies of each company in the group. We are made up of several dedicated companies (Eurolls, Cortinovis Machinery, Sictra, Team Meccanica, Teurema, and Vitari). I am responsible for both Sictra and Cortinovis Machinery which services the wire and cable manufacturers respectively with Drawing and Stranding equipment. The increasing need for larger, more flexible conductors, such as those utilized in the production of wind energy cables, is driving the industry towards drawing lines with higher capacity in terms of size and number of wires. This has also increased the demand for larger multi-wire annealers to handle this requirement.”

Cortinovis Machinery, Spa a member of the Eurolls Group, has totally redesigned its wide range of Double Twist machines. These new machines utilize a single bow made of carbon fiber which is shaped to have low aerodynamic resistance and therefore consumes less horsepower.   The machines, which range in size from 630 mm to 2000 mm, can be used for a wide range of products.   The 630mm, 800 mm, and 1000 mm machines are typically used for bunching and stranding of aluminium and copper conductors at very high speed, and proven efficiency and reliability.  These machines can be combined with a series of driven or non-driven payoffs for processing multi-wires, bunches, or single wires.   The larger 1250mm, 1600mm, and 2000mm machines are used for stranding flexible, rigid compacted, and rigid non-compacted copper, aluminium, and aluminium alloys. These machines are also suited for laying up of insulated conductors.

Teurema  S. L. EVM  Automatic  Spooler

The Teurema automatic spooler EVM was created for the production of precision laid wire coils with spools which can have a capacity of up to 5 tons. This double automatic spooler is composed of two spool working stations which are the wire collection station and the wire strapping/unloading/loading station. It comes complete with all of the necessary devices to ensure automatic handling of the wire, the cutting and subsequent threading of the wire, and the securing of the wire tail, too. All these operations improve line efficiency especially when operating with large diameter wires. The combination of all of these factors guarantees a drastic reduction in down times which are normally present during the spool changeover cycle. All parameters required for the formation of the pattern laid coil, as well as production information, are set on the spooler control pulpit.

Vitari Develops a Seven (7) Die Eight (8) Operation Machine for Cold Heading Complex Parts.

This machine is the result of multiple inquiries from our customers, specifically in the automotive industry as an extra die would enable the manufacturer to handle more complex parts otherwise not able to be manufactured with conventional cold headers. In addition to being able to manufacture more complex parts the accuracy too would be a plus with such a machine.  Features of this machine include:

• Smooth transfer cam movement permits accurate positioning of the part avoiding vibration and possible die miss-feeds
• Precision machining of the bronze-aluminum guides permit greater precision of the finished part
• Finger clamping system allows for widest range of head diameters available in the industry
•  Greater forging pressure compared to other competitive systems
