China Bttz Mineral Insulated Fireproof Cable Production Line

1. Equipment Composition
The line is composed of Copper Rod Pay-off,Copper Tape Pay-off,Tape Cutter, Tape Connection, Tape Cleaning, Magnesium oxide filling, Copper Tape Forming, Argon Arc Welding, Vertical Rolling, No.1 Annealer, Cooling Water Trough & Guide Pulley, No.1 horizontal Rolling , No.2 Annealer, Cooling Water Trough & Guide Pulley, No.2 Horizontal Rolling, No.3 Bright Annealing Device, Cooling Water Trough & Guide Pulley, Finish Products Sizing, Auto-Coiling(Take-up), Electric Control System
The whole production line is collected by computer and PLC,operate from HMI, all the motors are servo motors. Electric control cabinet adopts Rittal cabinet, the main components in the cabinet are imported brand or Sino-foreign joint venture brand. The main welding adopts Lincoln, USA
The equipment not only designs a set of active forming wheels and positioning devices with high machining precision, good positioning and abrasion resistance on the copper strip forming, which makes the forming stable and the joint reliable, but also uses welding seam monitoring and tracking and tungsten pole height control to make the welding more reliable and easier for workers to operate.
The equipment is equipped with strip splicing machine of argon-arc welding copper strip and a double disc pay-off strip device, which can meet the needs of continuous production. The copper rod splicer can be used to produce fireproof cables of any length.
2. Main technical parameters
2.1 The external diameter of welded copper sheath: φ42mm
The range of allowable copper strip thickness:0.85-2.0mm
Copper strip width B=(D-δ) .
2.2 The external diameter range of finished cable φ6-φ30mm
One production line completes the production of all BTTZ cable specification.
It takes only 5 minutes to replace the cable mold.
2.3 Adopt the DC High frequency argon welding arc starting, improve work efficiency.
