high speed railway stranded conductors

contact wire
110mm.mm;120mm.mm;150mm.mm

Every kinds of catenary and hanger which is made by copper and copper alloys in our company can be satisfied with the demand in TB/T3111-2005.Sometimes even pass through the demand. Also we can provide the products used in high speed railway which has the time speed about 350km.The main technical parameters are in the tables as follows. We can discuss with our customers and produce the products outside the standard.
