FAQ
1. What is a shielded three-core cable?
A shielded three-core cable consists of three insulated conductors bundled together and protected by a metallic shielding layer designed to minimize electromagnetic and radio-frequency interference.
2. What shielding constructions are available?
Available constructions include aluminum/polyester tape shield, copper wire braid shield, or a combination of foil and braid for enhanced EMI suppression.
3. What are the typical conductor materials?
High-purity annealed copper is most commonly used, available in both solid and stranded configurations to meet flexibility requirements.
4.Are customized structures available?
Yes. Custom conductor size, shielding ratio, insulation color, sheath material, and armor (e.g., steel tape or steel wire) can be manufactured upon request.
5.What’s the MOQ for your products?
A:Usually 100 meters
