The CTA series of copper‑silver trolley wire is offered by Hebei Kaihong Copper Alloy Co., Ltd. The product is a copper‑silver alloy contact wire used in electrified railway power supply systems. Its composition combines copper with a small proportion of silver to give high conductivity and corrosion resistance. The supplier lists applications in urban rail transit, subway, light rail, trolley bus, mining transport and lifting equipment.
In the rail sector, copper‑silver alloys typically contain 99.9 % copper and 0.1 % silver, delivering about 97 % IACS conductivity. Standard diameters for trolley contact wires range from 30 mm to 45 mm with a tolerance of ±0.5 mm. Tensile strength for this class of wire is usually 400‑600 MPa, and the material is annealed to improve ductility. Relevant industry standards include EN 50317 and IEC 60850, which dictate mechanical and electrical performance.
Railway infrastructure developers and equipment manufacturers are the main buyers of this wire. Buyers should confirm the exact alloy grade, diameter, coating and required certifications before placing orders. Trade terms such as Incoterms, lead time and payment schedule are negotiated per contract and should be clarified with Hebei Kaihong.

Importers should first obtain a mill test report that confirms the copper and silver percentages, electrical conductivity and tensile strength of the wire. A physical sample can be inspected for surface finish and dimensional accuracy before committing to a full order. These documents help ensure the product meets the technical requirements of the railway project.
Logistics arrangements need to be clarified with the supplier, including the preferred Incoterm (e.g., FOB Tianjin or CIF Shanghai), typical lead times of four to six weeks after order confirmation, and shipping method, usually sea freight in standard containers. Payment terms such as T/T against a confirmed purchase order or a documentary letter of credit should be negotiated to protect both parties.
Quality assurance is enhanced by commissioning a third‑party inspection that checks diameter tolerance, tensile strength and compliance with EN 50317. Buyers should also request certificates of conformity and the mill test report before shipment. Retaining these records facilitates customs clearance and provides a basis for any post‑delivery quality claims.
