Frequently Asked Questions
What is the primary application of this CTC production line?
This production line is specifically designed for manufacturing Continuously Transposed Conductors (CTC), which are highly critical components used in transformer windings to enhance electrical and mechanical performance.
What wire dimensions and strand limits does the machine support?
The line supports a wide range of specifications, including wire thicknesses of 1.12 to 3.15 mm and widths of 3.5 to 12.5 mm. Depending on configuration (84, 48, or 32-core options), it can process odd strand counts ranging from 5 up to 83.
How does the system ensure stable tension control during pay-off?
It uses a mechanical constant tension control system (adjustable from 0 to 10kg) along with a compulsive mechanical back-twist structure to prevent conductor deformation and maintain consistent product quality.
What safety mechanisms are in place if a paper wrapping breaks?
The taping device is integrated with an Omron phototube sensing system that automatically triggers a stop sequence if a paper break is detected, preventing raw material waste and damage.
Do you provide onsite installation and commissioning support?
Yes. We dispatch a professional technical team directly to the customer's site to handle installation, commissioning, and to provide face-to-face technical guidance and operational training.
