Technical requirements for wire and cable stranding equipment
Part 4
Cage stranding equipment
Subject content and scope of application
This standard specifies the technical requirements for wire and cable cage stranding equipment. JB/T5818.4-91
This standard applies to the JL series cage stranding machines for stranding wire and cable conductors and the CL series cage stranding machines for stranding wire and cable cores. This standard should be used together with JB/T5818.1 Technical requirements for wire and cable stranding equipment Part 1 General provisions. 2 Usage characteristics
2.1 It can regularly strand conductors (JL series) or cable cores (CL series). The stranded conductors or cable cores have good structural stability and mechanical back-twist.
2.2 The JL series can achieve single-layer stranding. 2.3 The strands used in the JL series are all solid core conductors, but the Y type can also use stranded conductors. 3 Model
Product model as specified in Table 1.
