Focus On Germany, Austria & Switzerland High speed tandem screening-extrusion solution

With the increased use of electronics in factories, even low voltage cables must be screened to avoid electric fog. rigid stranders is a slow process, and a production speed of 30m/min is the upper limit. Such a strander, typically with 48 bobbins, requires both a significant investment and a large installation space, coupled with the expense of foundations and high cross-section feeding cables. 2M-Tech states that there are large advantages to using SZ-screening over conventional screening. A screening line with 48 screening wires will cost approximately €700,000. This includes Conventional screening with Swiss wire and cable metrology company AESA Cortaillod has moved into a new building. The strategic construction was designed to meet the company’s development, production and services needs in terms of both quality and efficiency. In addition to supplying test equipment, AESA can provide knowledge transfer and services. Its laboratory is accredited (SAS) and globally recognised (ILAC). AESA can perform the periodic calibration of instruments and standards. The company also offers a range of training courses, with specialists who share their expertise and know‐how on

48-bobbin payoff frame, feeding capstan, SZ140 Ceander screening machine, CuB500 copper tape binder and torsion blocker. Because the payoff frames for the screening wire can be placed almost anywhere, frequently above the extrusion line, the minimum total length required between payoff and extrusion crosshead is just over 10m. Line speeds of up to 150m/min are possible, so tandem installation with extrusion lines is an efficient arrange- ment. KHU manufactures the CuB500 high-speed copper tape spinner with rotational speeds up to 1,700 rpm.

The spools for the screening copper wires can be 630mm, allowing very long runs. Only one production step is required, after laying up directly into the extrusion line. The total installed power of all components is less than 60kW.

available, particularly for special one-off tests. AESA can provide a wide range of tests that can be performed on samples on an ad hoc basis. Raw material budgets are of importance to the electrical cable industry, with a priority to optimise consumption and minimise scrap. AESA is constantly developing new metrological solutions to turn testing costs into profit generation. AESA’s solutions cover the testing of a wide range of conductors, from LAN to coaxial cables, and from insulated wires to high voltage cables. AESA Cortaillod www.aesa-cortaillod.com requirements, and the unit is compliant with the requirements of UL 1581, UL 2556, IEC 62230 and other standards. and measurement items such as the SP40A calibrator, so customers can carry out their own calibration and verification checks. The global service teams can also offer on-site or back-to-base maintenance and calibration services, with supporting certification to meet ISO and standard requirements.

topics related to the wider aspects of cable metrology. Training courses are also offered on more specific topics. The reliable verification of electrical parameters requires the use of accurate and calibrated instruments. However, such equipment is not always readily

Entry level spark tester With over 45 years of experience developing and supplying the latest spark testing technology, Zumbach has released a new compact, low-level investment model suited to coiling,

confectioning, rewinding, packaging and space-restricted applications. Key features of the DST 10 are an integrated web server over TCP/IP PoE interface; ease of OEM integration through standard bus connectivity (Ethernet IP, Profinet, Profibus, etc); bare patch/pin hole determination; and fault position history, using length input signal. It can handle diameters of up to 30mm, and operates in a 0.5 to 10 kV DC range. Bead chain, brush electrode and combination solutions are specific to the
