This production line is suitable for Cu or Al stranded wire core to make XLPE cables from 6kV to 35kV. It is of Semi-catenary type, in which the triple-layer cable is heated by means of short-circuit method, cross-linked with nitrogen gas, cooled by water is 14 sections of tubes, heat released by warm water, then cooled in cooling water trough. The XLPE cable is in accord with the standard of GB/T 1270b-2002 and GB/T 11017-2002.
1, The main control system is a new generation Siemens S7-1500 and TP1900 touch screen, which can be connected to the X-ray device, and reveal the corresponding measurements. The setpoint and production parameters (temperatures, pressure limits, speeds, torquelimits, cable dimensions, etc.) are stored in the HMI “recipe” database. Most of the process & setpoint values can be logged in the Computer SQL database for analysis and a production report with statistical values can be generated per drum or batch. The computer can also be used as a remote monitoring. Each single machine is equipped with a electrical cabinet controlled by PLC, so that the signals are not interfered and the control precision is high. The main control cabinet communicates with each single control cabinet via Profinet bus, which can realize remote control.
2. CCV software: independently developed by our company with intellectual property rights; high-performance PACC intelligent operating software: with the most advanced process calculation operating system, set the parameters according to the production process, and after starting the operation, the line speed will follow the pipeline temperature automatically up to the set speed. When the machine is stopped, the line speed decreases with the pipeline temperature, and the equipment is stopped at a slow speed to reduce product waste and save costs. All production data’s can be displayed; views and curves are available for viewing .
3. SAG; for better reliability and cable stability, the SAG is equipped with 2 different control units; non-contact magnetic system and camera controller. These 2 control units can be switched.
