Component Specifications

Definition
A conductor wire is a fundamental electrical component consisting of one or more metallic strands, typically copper or aluminum, that provide a low-resistance path for electric current flow. In terminal blocks and wiring applications, it serves as the primary medium for transmitting power or signals between connection points, circuit breakers, and electrical devices. The wire's construction includes conductive core material, insulation layer, and sometimes shielding or jacketing for protection against environmental factors and electromagnetic interference.
Working Principle
Conductor wires operate on the principle of electrical conductivity, where free electrons in the metallic material move in response to an applied voltage, creating current flow. The wire's cross-sectional area, material resistivity, and temperature coefficient determine its current-carrying capacity and voltage drop characteristics. Proper sizing ensures efficient power transmission while preventing overheating and energy losses.
Materials
Primary materials: Electrolytic Tough Pitch Copper (ETP-Cu, 99.9% purity), Aluminum Alloy (AA-1350). Insulation: Polyvinyl Chloride (PVC), Cross-Linked Polyethylene (XLPE), Thermoplastic Elastomer (TPE). Temperature ratings: -40°C to 105°C for standard applications, up to 200°C for high-temperature variants.
Technical Parameters
  • Stranding 7 to 61 strands (flexible types)
  • Resistance ≤ 0.0175 Ω·mm²/m for copper at 20°C

Frequently Asked Questions

What factors determine the appropriate wire size for terminal block applications?

Wire size selection depends on current load, voltage drop requirements, ambient temperature, insulation type, and applicable standards like IEC 60228. Oversizing prevents overheating while maintaining efficiency.

How does stranded wire differ from solid wire in industrial applications?

Stranded wire offers better flexibility and vibration resistance, making it suitable for moving applications and easier termination in terminal blocks. Solid wire provides better rigidity for fixed installations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
