Is fiber optic communication affected by high-voltage power lines
Properly protected, optical fibers can be used in high-voltage installations without fear of damage or degradations of its performance. In all situations where copper telecommunication lines (remote grounds) are allowed into high voltage environments catastrophic failures may occur due to a GPR event, endangering personnel, equipment and critical communication lines. OPAC cables have been. Many electric utilities are installing high capacity fiber optic cables and wires on their high voltage lines to satisfy their own internal communication needs and to gain additional revenues by leasing excess capacity to telecommunication network providers. This integration brings benets for the. -

What types of cold-joints are there
Cold joints, unlike cracks that form in hardened concrete through tensile restraint, are not gaps in the concrete but merely seams containing no appreciable void structure. They are usually linear, closely joined and bonded. While most are deliberate and strengthen the structure, one, in particular, does not: the cold joint. This article explores the causes of cold joints, how they can be prevented, and their distinctions from other types of joints in. But do you know what concrete cold joints are? A cold joint in concrete is an area or surface with a structural discontinuity caused by the delayed concrete pouring between two layers of concrete. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with the fresh mix. A cold joint in concrete, also known as a construction joint, is a point in a concrete structure where fresh concrete is placed against previously cured or partially cured concrete.
