NEW OVERHEAD CONTACT SYSTEM DROPPER CONNECTOR FOR RAILWAY LINE ELECTRIFICATION

NUEVA GRIFA DE PENDOLA DE HILO DE CONTACTO PARA ELECTRIFICACIONES DE FERROCARRIL

The part by which the hanger grips of the power cable of an electrified line is known as a hanging clamp. This part is the most numerous of all in railway electrification installations. They may have two forms. They either maintain the hanger in a rigid position or else they allow it to move. The main problem is to try to ensure that the clamps are made of the smallest possible number of pieces, for various reasons--simplicity, ease of manufacture, and lower costs. They should not have threaded elements which are disadvantageous; they should be of low volume to use less raw material and it should be possible to use only one type for all the kinds of hangers in use, in order to achieve standardisation and simplicity. This clamp, compared with 16 others used in various national and foreign lines, has all the above-mentioned characteristics, as it is all in one piece and does not require any safety securing elements. It serves equally well for a lateral hanger where the two wings are placed in the grooves of the power cable. Its weight of 28 grams makes it the lightest of all those known and studied. Its installation will not be immediate but it must be ready and tested for when substantial new electrifications are under discussion.
