LINEAR RESISTANCE MEASUREMENT ON-THE-LINE ResTest 8134 Sole system able of accurately measuring copper conductors directly on the stranding machine DESCRIPTION Cables are usually supplied with unnecessary and expensive excess material (at least 2 - 5% safety margin). A reliable and non-destructive measurement directly on the stranding machine allows reducing the safety margin, thus generating significant savings. ResTest 8134 avoids cutting samples for the laboratory. It allows rapid results, even at high temperature and of extremely compacted strands. AESA’s dry heating system drastically reduces the temperature stabilisation time. The patented measuring method of ResTest 8134 doesn’t require insulating from ground potential the pull-off capstan and the winding spool (costly and dangerous modification). Important savings in production o o o Directly on the stranding machine o o our patented measuring method allows reliable measurements directly on the line unlike other solutions on the market, it is not needed to insulate the production line Dry temperature stabilization system o o raw material savings enable pay-back in less than one year testing without generation of any scrap rapid check of production adjustment effects thanks to a short feedback loop fast heating system and stabilisation at the conductor's temperature no use of coolant or water our specification relates to the overall measurement, not only to the micro

DESCRIPTION Temporary stop the production line, position and adjust the equipment towards the rope (height and slope). Tighten the jaws and close the cover. Set the basic data and start the measurement. The equipment measures the rope temperature and the heating elements enable the whole area surrounding the measurement setup to quickly be brought up to the temperature of the conductor. All the heating elements are electronically regulated and controlled by microprocessor. After a few minutes only, the temperature is stabilized. The equipment induces a regulated alternative current in the...

ResTest 8134 INTEGRATED FUNCTIONS Creation of a library of strand specifications Each specification includes: • A specification name • The nominal resistance • The maximum allowed deviation • The nominal temperature • The material being used and its physical constants a (temperature coefficient) and p (resistivity) Starting a measurement The users can access to two different menus: 1. Direct measurement: All parameters can be modified (as a: Temperature coefficient, p Resistivity, allowing to show the section of the conductor in [mm2], ©n: Nominal temperature at which the resistance value...

ISO 17025 certified control box type 7394 This option is required to check the accuracy of each range of the ohmmeter. This option also allows to simulate various test conditions in order to check the device. Delivered with ISO 17025 certificate 2. This option is required to verify the overall accuracy of the equipment (including the ruler). Delivered with ISO 17025 certificate 3. Label printer type Brother QL-700 This printer is directly connected to the USB port and prints the measured data and test conditions on labels (example here below). Full page printer This printer is directly...

Cable tensioner for sample measurement (off-the-line) Specially designed for laboratory purposes (sample testing), this tool allows a very accurate copper and aluminium measurement by straightening the sample and twisting it if need be (note: the pulling force is not measured. Protective cover This option covers the complete system in order to protect it when not in use. The commissioning will be performed on site. It will be organised as soon as the equipment is arrived at the end-user plant. The commissioning includes the installation of the equipment as well as the training of the...
