To meet the ever-changing demand in the Chinese market, it was very important for Dalian Jinzhou Cable to find a versatile solution for cable production. The possibility to manufacture both rubber and XLPE cables on the same line was one of the most important reasons why Dalian selected Maillefer as their supplier.
Dalian Jinzhou Cable, China
Dalian Jinzhou Cable is one of the biggest wire and cable manufacturers in Northern China. It has headquarters in Shenyang city and a branch in Dalian city. Dalian Jinzhou Cable’s first rubber cable production line from Maillefer is up and running. The new line opens doors to producing cables for the building, wind park, shipbuilding, mining, rolling stock, and heavy industry.
Multiplied production capacity with 60% increase in overall efficiency
Dalian Jinzhou Cable chose Maillefer’s high-speed rubber insulation and sheathing line with Super Steam technology, also called Super Cure in China. The right capacity and lower production costs are key issues in China. The Super Steam process with low steam pressure multiplies the capacity in rubber cable production. Savings come from optimized usage of extruded materials, minimized scrap costs, and low steam and energy consumption. In total, Dalian’s overall efficiency has increased by up to 60%.
“Our cooperation has given us not only new technology, but also process and material knowledge to guide our customers to profitable choices.”

The Solution
It was important for Dalian to find a solution covering different applications and product types. Dalian listened to their customers’ feedback and acted on market demand. They appreciated Maillefer’s adaptive technologies, process know-how and customer support when selecting the high speed rubber line with Super Steam technology. One production line offers optimum processes for all types of cables: Steam Curing, Super Steam Curing, Nitrogen Dry Curing. Also, the curing calculation program NSS has been a very useful tool for production planning.
When production processes are stable, it is possible to maintain high cable quality and secure lead times. Automated functions, process data reporting, and independence from steam pressure have helped to create production conditions which are favorable to successful production of even the most sensitive cable constructions.
