Line Splice
In telecommunications, a line splice is a method of connecting electrical cables (electrical splice) or optical fibers (optical splice). Splices are often housed in sleeves to protect against external influences. Splicing of copper wires The splicing of copper wires happens in the following steps: * The cores are laid one above the other at the junction. * The core insulation is removed. * The wires are wrapped two to three times around each other ( twisting). * The bare veins on a length of about 3 cm "strangle" or "twist". In some cases, the strangulation is soldered. * To isolate the splice, an insulating sleeve made of paper or plastic is pushed over it. The splicing of copper wires is mainly used on paper insulated wires. LSA techniques (LSA: soldering, screwing and stripping free) are used to connect copper wires, making the copper wires faster and easier to connect. LSA techniques include: * Wire connection sleeves (AVH = Adernverbindungshülsen) and other cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the unde ...
