Import Copper-Magnesium Trolley Contact Line — Buy in Bulk from Supplier in China

The copper-magnesium trolley contact line supplied by Hebei Kaihong Copper Alloy Co., Ltd. is a high-speed electrified railway transmission conductor. It is manufactured from a copper-magnesium alloy designed for catenary applications. The supplier lists this product among its range of copper-magnesium alloy wire, dropper line and other railway special products. The line is intended for use in overhead contact systems that require both conductivity and mechanical strength.

Copper-magnesium alloys typically contain 0.2-0.5% magnesium, which improves tensile strength while retaining good electrical conductivity. In the railway sector the conductor is often produced with a diameter between 20 mm and 30 mm and a tensile strength around 250 MPa, meeting the EN 50317 standard for contact wires. The material offers corrosion resistance and thermal stability suitable for temperatures from -30°C to +120°C. Such specifications allow the line to sustain the dynamic loads of high-speed train operations.

Railway infrastructure contractors and electrification system integrators are the primary buyers of this trolley contact line. Procurement normally involves confirming the required conductor diameter, tensile strength class and compliance with EN 50317 before placing an order. Interested parties should request the supplier’s detailed quotation, packaging options and Incoterms to finalise bulk trade terms.
