Cable can flex at –50˚C

Dimensional measurement Zumbach offers a complete line of modular, single-axis ODAC ® laser gauges, available either mounted on a rail or as components with separate sender and receiver units for flexible installation in any position. Using high precision, telecentric optics, it is possible to mount sender and receiver units at a distance to each other (depending on the model, up to 3m/10ft). This enables multiple sender/receiver pairs arranged in the same measuring level, thus offering a multi-axis measurement. With almost unlimited installation and configuration possibilities, these gauges can be used in most manufacturing processes, including the extrusion of cables, hoses, and profiles or in the steel and metal industries for drawing, grinding, cold and hot rolling of rods and tubes. An advantage of the ODAC line is the high scan rate, up to 2,000/s (depending on the model). Since 1980, GER SA has specialised in the sale of new and second-hand machinery for wire and cable, tube and sheet works, for the ferrous and non-ferrous industry. The company sells single machines or complete plants and lines for most products including steel rod and wire, non-ferrous wire, steel ropes and electrical insulated cables. A wide range is available from stock, or GER will source equipment as required to suit the individual customer. Machines are test run before shipment, or can be installed and commissioned at the customer’s plant where full training for operators can be carried out.

Nexans has launched Iceflex ® , believed the world’s first marine and offshore full range cable qualified for extremely low temperatures. This range of cable, which is intended for use in a wide variety of shipboard and offshore/onshore applications, remains highly flexible at temperatures as low as –50°C, while ensuring advanced fire performance. Normally cables with conventional insulation become stiff and brittle in intense cold, which can be a problem in places such as the Arctic. Iceflex adheres to all current environmental and safety standards, and the cable is able to meet the challenge of severe cold or ice storms. It operates reliably in icy, snowy conditions under a variety of technical applications, and can survive in exposed conditions onboard, topside or in frozen ground or permafrost. The cable also easily adapts to abrupt temperature variations such as those taking place during spring and autumn. Iceflex is available in two versions – halogen-free flame and fire retardant (HFFR) and halogenated versions. Iceflex also has a high impact-resistance to withstand sustained or violent physical shocks, such as vibration or operational stress. Salvatore Di Giorgio, Nexans global segment manager for shipbuilding and offshore top side market, says: “The ability to withstand these environ- mental constraints is a major technical achievement, which will make it easier to safely develop oil and gas fields, shipping routes and processing plants in the high Arctic.”

8-point measurement

combined with pulse-driven laser diodes. The laser diodes project a picture of the cable on the latest available CCD-line technology in each measuring axis. Within microseconds eccentricity, diameter and ovality are calculated from the image of the product. A cloud diagram is an additional visualisation of the measurements being made on the processor system Ecocontrol. With the help of the cloud diagram the distribution of short-term eccentricity variations is shown. Each point represents an actual single value of the eccentricity with regard to amount and direction. The overall distribution of the cloud diagram easily highlights the standard deviation of the eccentricity.

Sikora’s Centerview 8000 includes a non-contact gauge head to provide continuous online measurements. The 8-point eccentricity, 4-axis diameter and 8-point ovality measurements ensure the highest accuracy. The system is suitable for use in the production of coaxial cables, LAN cables, automotive and installation cables. Sikora offers two Centerview 8000 versions, for product diameters from 0.1mm to 10mm and 0.5mm to 25mm. The Centerview 8000 combines an optical and inductive measuring tech- nique. With the inductive measuring circuit the position of the conductor is recognised and the gauge head automatically centred to the cable position. Guide rollers and manual adjustment are unnecessary. The optical part of the system is based on the principle of diffraction analysis
