Cables, Wires – Single Conductors

1. What are Single Conductor Wires?

Single-core conductor wires are a type of wire consisting of a single metal conductor. Their core structure consists solely of the conductor material and an outer insulation layer. Unlike multi-strand, twisted flexible wires (such as flexible conductors), single-core conductors lack the flexibility inherent in twisting multiple filaments. In specialized applications (such as locomotive wiring harnesses), a pre-set helical structure can be used to match the parameters of the finished twisted-pair cable, eliminating internal stress and improving stability.

 

2. What are the Core Technical Features of Single Conductor Wires?

1) Mechanical Performance:

The conductor cross-section is a single solid structure, offering superior deformation resistance compared to multi-strand wires, but with lower bending flexibility.

 

The helical design prevents torsional deformation during use, making it suitable for use in vibrating environments.

 

2) Electrical Performance:

High-purity copper/aluminum conductors ensure low-resistance conductivity.

 

Insulation materials include PVC and XLPE, with voltage ratings ranging from 600V to 10kV and operating temperatures up to 150°C.

 

3. What are the Applications of Single Conductor Wires?

Industrial Equipment: Locomotive cable systems, industrial robot power harnesses.

Electronic Appliances: Internal wiring in home appliances (such as UL3321-certified wires) and static circuit connections.

Aerospace and Energy: Power transmission in fixed installations, not dynamic bending locations.
