Description

General information:

The contact wire is made of electrolytic copper or copper alloy with the addition of additives (cadmium, tin) for imparting additional strength. catenary wire made of round or shaped copper wire having two longitudinal grooves for contact with the clamps susceptor. Contact wire of round copper profile is used to supply current bridge cranes, and is carried out of the profiled strand is applied in the contact networks to transport electric power: trams and trolleys.

To supply electric railways use contact wire section 100 and 85 mm2. Primarily as a requirement imposed on the contact wire is smooth contact surface. Cracks and traces of coarse broach reduce the mechanical strength of the wire. Also the wires should go through the mechanical tensile test, torsion and bending. Torsional three turns 360 ° around the axis without fracture (wire length 250 mm.) On the bending wire clamped in a vise to withstand bending through 90 ° in one direction and a 180 ° bend in the opposite without fracture. Trolley wire catenary MF delivered on wooden drums of diameter not less than 0.6 m. In this case the working surface of the wire must be strictly facing inwards of the drum, without twisting the wire. Copper wire MF 85 made from pieces of wire, which are then interconnected soldered with silver solder. 1 ton of wire must not be more than 15 adhesions. To provide wire strength in locations spikes tear resistance should be not less than 97% of the resistance to rupture of whole piece of wire. In operation wire can cause overheating annealing soldering material and reduction of mechanical strength. To avoid this, you need to avoid overheating in the operation and installation of wires.

Contact MF grade wire (copper wire shaped) cross-section is made 85, 100 and 120 mm2.
