What is SZ Stranding Line Machine?

The stranding line machine is a kind of mechanical equipment that can be widely used in various soft/hard conductor lines and electronic lines. It can twist multiple single conductors into one strand to meet the process requirements of the wire. Fiber optic Stranding line machine are generally divided according to the stranding method. Generally, they can be divided into single stranding machines, sz stranding line machines, high-speed stranding machines, back-twisting machines, cage stranding machines, frame stranding machines, tubular stranding machines and disc stranding machines. Hard conductor line: copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc. Electronic wire: power cord, headphone wire, telephone wire, PVC wire, network wire.

The sz stranding line machine refers to a mechanical equipment that twists a single conductor into one strand by left and right stranding. SZ Stranding line machine can not only improve productivity, but also has simple equipment and is easy to install. Its rotating part is very small and light. It reduces energy consumption and equipment manufacturing costs. SZ Stranding line stipulates that the outer layer is laid to the right and the other layers are laid to the left. The IEC standard does not stipulate the lay direction for twisted wires and cables, so sz Stranding machine complies with IEC standards.

Advantages and Application of SZ Stranding Machine

For fixed cables such as power cables, control cables, signal cables. And some electrical equipment cables that do not bear tension and require flexibility, SZ Stranding line machine is more suitable. The typical application of SZ Stranding Machine is long-distance submarine power cables. It is also suitable for the manufacture of the outer shielding layer of the insulated core. SZ stranding greatly reduces the number of cable joints. It reduces potential ground faults and increases the length of the cable. In addition, there are no problems with the laying and construction of SZ Stranding cable.

SZ Stranding Line Machine Types

Type	Tubular wire storage and twisting machine	Double stranding machine	Clamping type cable twisting machine
Conductor cross section/mm^2	<25	15~16	25~300
Pitch/mm	50~300	300	1450~2000
Speed/(r/min)	<500	Large twisting head 500, small twisting head 1000	< 180
Maximum line speed/(m/min)	80	Large twisting head 150, small twisting head 300	75
Application	Signal, control cable outer sheath or neutral line, optical cable	Communications, power and control cables	Medium and large cross-section power cables

In addition to the types listed in the table, there are also spiral, swing, double breathing and reciprocating stranding. But the basic principle is the same, the difference is that the storage length is different. For example, for the tubular storage machine, in order to extend the storage length. It can be made into several sections in series.

Important technical parameters of SZ Stranding Machine

Machine speed, stranding cross-sectional area, wire diameter, lay pitch, drive motor, stranding take-up drum, noise index, vibration index.

Toem’s high-speed SZ Stranding Line machine uses variable frequency control, which can easily control the speed. Its vibration index is small and the stranding is stable. The wire diameter of SZ Stranding line is high in accuracy and the machine speed is fast. It greatly reduces mechanical noise and improves stranding efficiency.

Summary

In the future, SZ Stranding Line machine may add a certain amount of cushion core to the S-Z layer. This can maintain the flexibility of the cable and improve its use value.
