The company's leading product, 35kV three-layer co-extrusion cross-linking production line, is a mature and finalized product that integrates the advantages of mechanical, electrical, process, operation, appearance and other aspects on the basis of digesting and absorbing the advanced technology of similar equipment at home and abroad to the market.
This production line is suitable for the production of 6-35kV cross-linked polyethylene insulated cable with copper or aluminum hinge core. The pipe laying form is semi catenary type. The three-layer co extrusion crosslinking production line with the short circuit heating method of crosslinking pipe, nitrogen crosslinking and water cooling method is adopted. The crosslinked cable products meet the relevant structural standards of GB / T12706-2002。
characteristics:
1、Progressiveness: the product structure is reasonable, the technology is advanced, and the matching of all parts reaches the best standards both at home and abroad.
2、High automation: PLC, DC control, operation panel, sensor and temperature control system are all imported components, so that the products can achieve the best state of mechatronics, synchronization and smooth operation in production.
3、Appearance: the product has achieved the effect of harmonious color and durability, not only achieving advanced and stable production, but also reflecting the aesthetic feeling of the product appearance.
4、Good quality and low price: This product, on the basis of embodying the advanced nature and aesthetic feeling, aims at better and faster expansion of the market share and the user's understanding and selection. The company's product price is the lowest among the similar products, and the service reaches the best grade, so it becomes a good example of high quality and reasonable price.
