“Maximum safety through comprehensive quality management” could be the slogan of the Lapp Group, one of the
leading providers of integrated solutions and brand products in the field of cable and connection technology. Ensuring
a consistently high product quality is clearly the company's top priority. A range of product features such as functionality or service life are highly dependent on the climatic conditions. Ever-increasing requirements are placed on the thermal resistance and the aging behavior of the plastic parts used – particularly in the field of cable and connection technology – as these must be able to function reliably without problems under extreme climatic ambient conditions. For example, heat can take its toll on the plastic jackets and insulation materials of the cables, making them age prematurely and become brittle. To determine how well a cable is going to last over the next decades, the Lapp Group rigorously tests the material. These tests significantly speed up the aging process.
Simulating artificial aging
25 different drying and heating chambers from the BINDER ED and FD series are used for this purpose. The quality tests and certifications are performed according to national and international VDE, UL, EN, ISO, and IEC standards. The thermal aging process of cable jacket materials is simulated in the test laboratory by exposing the materials to age accelerating conditions (temperature increase, high rate of air exchange). The artificial aging of products through controlled climatic conditions identifies their weak points and can predict material fatigue or even material failure. The acceleration effect is induced by varying temperature increases up to 300 °C. The tests are performed with both natural and forced convection. “Thanks to natural convection and the high rate of air exchange, all thermal processes in the ED series drying chambers are highly efficient,” explains Michael Hagenmüller, laboratory manager at Lapp. “The FD series drying chambers with forced convection are mainly used when we require rapid process dynamics.” Thanks to the APT.line™ technology, the chambers ensure a homogeneous temperature distribution across all levels even at full load.
“The BINDER chambers meet all requirements extremely reliably; they impress with a high temperature accuracy and precisely maintain the defined ventilation parameters in line with the time specifications,” says Michael Hagenmüller. “And the fact that they are excellent value for money was obviously another advantage.”
