Product Description:
The double twist stranding machine is a highly efficient piece of
equipment in the field of wire and cable production.
This machine is mainly used for twisting multiple strands of wire
together to form a stronger and more durable cable. It can handle
different types of wires, such as copper and aluminum, with
specific diameter ranges. The adjustable stranding pitch range
allows for customization to meet various production requirements.
With a reasonable rotation speed and a large take-up reel diameter,
it ensures continuous production and smooth operation. The
pneumatic brake disc provides reliable braking for safety.
This machine is essential for manufacturing high-quality cables for
electrical power transmission, telecommunications, and various
industrial applications.
Feature:
- Carbon-fiber stranding bow, much lighter and more durable than
the spring steel
- The adoption of communication module reduces the number of
circuits in the current collector
- The intellegent oil coiling system with high power compressor
enables for non-stop high-speed operation
- Servo motors save upto 15% electricity

Applications:
The double twist buncher/strander is a highly productive apparatus
employed in the manufacturing of Unilay copper and aluminum
conductors, which are utilized for low voltage (LV cables) and
medium voltage (MV cables). The 1250 high-speed stranding machines
can partially substitute tubular stranders and rigid frame
stranders. In contrast to tubular stranders and rigid frame
stranders capable of manufacturing such products, this machine
boasts the features of high production efficiency and smaller floor
space. Currently, it is the most cost-effective equipment for
stranding power cable conductors of 19 or fewer.
