Complete Collection of Cable Forming Process Technologies for Electric Wires and Cables

Cable-forming machines can generally be divided into two types: cage cable-forming machines and high-speed cage cable-forming machines. Among them, the high-speed cage cable-forming machine is used for the stranding of copper-core aluminum stranded wires and bare aluminum wires. Meanwhile, it can also be used for the cable-forming of plastic power cables, rubber-sheathed cables and other products.

 

Introduction to Cable Laying-up Machines

 

Cable laying-up machines can generally be divided into two types: cage type cable laying-up machines and high-speed cage type cable laying-up machines. Among them, the high-speed cage type cable laying-up machine is used for the stranding of copper-clad aluminum stranded wires and bare aluminum wires, and can also be used for the cable laying-up of plastic power cables, rubber-sheathed cables and other products.

 

Application of Cable Laying-up Machines
This series of products are suitable for multi-core rubber cables, rubber cables, signal cables, plastic power cables, cross-linked cables, telephone cables, control cables, etc. with various cross-sections for cable laying-up manufacturers.

 

Features of Cable Laying-up Machines
This series of cable laying-up machines are essential equipment for cable production. The equipment has a wide variety of types and complete specifications, and is widely applicable. Users can select the corresponding cable laying-up equipment according to the needs of their own production products. The equipment has the functions of reverse twisting and non-reverse twisting. The reverse twisting methods include reverse twisting ring reverse twisting, planetary gear train reverse twisting and sprocket reverse twisting. The pre-twisting forms are divided into manual pre-twisting and electric pre-twisting. The wire spool clamping is divided into manual clamping and electric clamping. The take-up is divided into shaft and shaftless forms.

Types of Cable Laying-up Machines
The equipment used for cable laying-up, that is, the equipment that twists the insulated wire cores together and performs filling and lapping, is called a cable laying-up machine. Cable laying-up machines are divided into ordinary type and drum stranding type. The ordinary type cable laying-up machines include cage type and drum type, and the cable laying-up speed is generally below 10m/min. Large cable laying-up machines are made into drum type and can perform cable laying-up of three-core, four-core and five-core cables. For example, 1 + 3/1600 and 1 + 3/2400, 1 + 4/1600, 1 + 4/2400 cable laying-up machines, and the maximum pay-off reels are 1600mm and 2400mm respectively. Medium and small cable laying-up machines are made into cage type, and the stranding part is like the stranding cage of a wire stranding machine, with specifications and forms such as 1 + 6/1000 and 1 + 6/400. The drum stranding type cable laying-up machine is a relatively new cable laying-up equipment with high production efficiency and a speed generally above 30m/min. It has a wide application range and can be used for cable laying-up of various power cables, as well as for cable stranding of communication cables, control cables and large-section ultra-high voltage cable split conductors.

 

Application of Frequency Converters in Cable Laying-up Machines
Pay-off System
The pay-off rack is composed of 12 passive pay-off units. The pay-off tension is generated by the friction of the steel strip against the rotating shaft of the pay-off reel to realize the passive tension pay-off of the wire.

 

 

Traction System
Multi-strand wires and belt pressure rollers are used for traction to realize the system speed setting and system speed reference. The frequency converter outputs the effective value of the speed to the PLC through the RS485 communication interface. After the PLC processes the data of the stranding bow and the take-up machine driver, it outputs the data to the stranding bow and take-up driver through the RS485 interface.

 

Dancer
The wire tension is adjusted by adjusting the counterweight of the wire passing through the wire guide wheel or adjusting the air pressure of the air cylinder. During the take-up process of the take-up machine, the change of the dancer position is sent to the PLC to adjust the change of the take-up speed of the take-up machine caused by the change of the winding diameter, so as to realize the constant linear speed and constant tension winding control.
