Couplings are cable, Cable and conduction production

Connection of cables twist is applied in the least responsible lines as does not provide reliable contact for a long time. The veins connected with the help to twist and twist to the soldering isolate by means of dielectric sleeves. For connection of coaxial cables contact of veins does not suffice — it is necessary to provide preservation of electric parameters. Therefore coaxial cables connect to the help of special sleeves. Optical fibers splice by means of welding, or with use of one-piece connectors. When merging optical fibers preparation of optical fiber is of great importance: end faces of optical fibers have to be the most smooth, the surface should not be polluted by dust. Modern welding machines for optical fibers allow to control quality of welding on the place for what contain a microscope, and also the test laser allowing to check attenuation of a signal when passing a welded seam. Veins of power cables connect to the help of tips which are pulled together with bolts. Tips fasten to a vein or by means of bolts, or compression.
