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.
