  • Test Equipment

    The TVAB abrasion testing equipment is so precise that it has set the standards for ISO 6722-1. It has been desi-gned to test the durability of cable insulation under ext-reme conditions, and mea-sures very specific durability variables.

    This device does abrade the surface of the insulation in both directions along the longitudinal axis of the test sample. A counter will re-cord the numbers of cycles to failure. When the needle abrades through the insulati-on and makes contact with the conductor, the machine will stop operating.

    Abrasion test apparatus TVAB 5420-7N


    ¥ The testing can be performed on main types of wires with different types of insulation materials, with exception of certain types of very soft and tough materials. The testing can further more be per-formed on wires with all main insulation thickness with an overall diameter from minimum 1,0mm up to 6,0mm. Recommended over all diameters for test is 2,0mm.

    ¥ The principal of testing operation is built on simulating the scraping of the wire against a sharp metal edge. The wire to be tested is placed in a special fixture in the testing equipment.

    ¥ A loaded abrasion tongue effects the abrasion of insulation with a well defined piano wire moving forwards and backwards along the wire. The wire resistance to abrasion is determined by the number of cycles that are performed before the wire insulation has been worn away. The equipment stops in this position automa-tically as there will be an electric short circuit between the piano wire and the wire conductor. The number of cycles can directly be noted from the counter on the equipment.

    ¥ The testing can be performed with the wire either in the air or submerged in liquids (i.e. water). The testing under water makes it possible to detect micro cracks in the wire insulation. The equip-ment will not have a container for this type of testing in standard version.

    ¥ The testing equipment is furthermore equipped with an effective cooling fan to avoid negative effects troughs heating of equip-ment by own produced heat during testing procedure.

    ¥ Diameter of needle: (0,45 ± 0,01) mm Type of needle: Spring wire (polished) material according to ISO 6931-1; Frequency: (55 ± 5) cycles/min (one cycle consists of one reci-procating movement); Displacement of the needle: (20 ± 1) mm; Length of abrasion: (15,5 ± 1) mm; Mass: The vertical force on the test sample shall be constant under dynamic conditions;

    ¥ Test sample mounting force: The test sample shall not move during test. If fixing is necessary, the tension applied on the conductor shall not exceed 100 MPa (N/mm2);

    ¥ Apply a total vertical force as specified in table 11 to the test sample. Determine the number of cycles by taking four mea-surements at a temperature of (23 ± 1)°C. After each reading, move the test sample 100 mm and rotate it clockwise 90°. Change the needle after each reading. The minimum value shall be noted.

    ¥ The TVAB abrasion testing equipment is marketed and serviced exclusively by Inhol B.V.

    The PTL/Compo flattening line is for flatte-ning heat-shrinkable tubing to be used as identification sleeves. This line is capable of flattening expanded heat-shrinkable tubing of multiple diameters ranging in diameter from 2.4mm up to 76.2mm.Consistent flattening can be easily achie-ved. The flattener has been designed and equipped with controls for product consis-tency and reproducibility.Halogen-free and halogenated, flame-retarded polyolefin heat-shrink tubing in 2:1 and 3:1 shrink ratio, as well as other heat-shrinkable tubing (such as fluoropolymer based products) can be easily flattened to any desired ‘puff’.

    Our cutting lines have been designed for cutting thin-, medium- and thick wall tubing.
