method and system for accelerated reliability testing of telecommunications cable with thermoplastic materiau0 shirt

摘要

the invention refers to a method and a plant for attempts to accelerated reliability of telecommunications cables mantles of thermoplastic materials.the invention consists in that a population composed of not preparing samples from which a part is inserted into an enclosure with water at temperaratra 45 degree c + - 0,1 degree c and the other side is inserted into an enclosure with vaporide water saturated samples are kept in this state for 3 years and periodically at 3 months make measurements on electrical parameters dit's transmission.the installation is made up of a test block to variations of temperature and humidity which transmits signals of a switching block whose order is taken from a block of measure and accountrole.
