PVC Wires
- PVC wires are general-purpose wires and cables that use polyvinyl chloride (PVC) as insulation and/or sheath.
- As one of the most widely used and oldest types of wires, they have become the benchmark product in the electrical installation field due to their excellent overall performance, mature technology, and excellent cost-effectiveness.
Description
PVC Wires
Conductor: Copper (TU1/TU2), tin-plated copper or aluminum, in round or fan-shaped strands.
Insulation layer: Polyvinyl chloride (PVC) mixture.
Sheath layer (if any): Polyvinyl chloride (PVC) blend, typically gray, white, or black.
Common models:
BV: Copper core PVC insulated wire (single core, for fixed wiring).
BVR: Copper core PVC insulated flexible wire (multi-strand flexible conductor).
RV: Copper core PVC insulated flexible wire (softer, used for internal wiring of household appliances).
RVV: Copper core PVC insulated PVC sheathed flexible cable (multi-core, lightweight sheathed wire).
VV/VLV: Polyvinyl chloride insulated and polyvinyl chloride sheathed power cable (low voltage power transmission).
Application
Building electrical systems: Indoor fixed wiring (BV/BVR), lighting circuits, and socket circuits.
Home appliances: Internal wiring and power cords (RV/RVV).
Mechanical equipment: power and control circuits, internal wiring of distribution cabinets.
Automation systems: signal transmission and instrument connection.
Temporary power supply: portable power cords, extension cords.
General low-voltage power distribution: Dry indoor environments with no special requirements for environmental protection and smoke.
Features/Parameters
High cost-effectiveness: With abundant raw materials and mature manufacturing processes, it is one of the most cost-effective types of wires.
Good processing performance: It is easy to extrude and can be made into various colors for easy identification.
Stable mechanical properties: It has good wear resistance, tensile strength and a certain degree of flexibility.
Chemical corrosion resistance: It has good resistance to acids, alkalis, oils, solvents, etc.
Reliable electrical insulation: High dielectric strength, meeting the insulation requirements of most low-voltage applications.
Adjustable flame retardancy: Good flame retardant effect (ordinary or flame retardant) can be easily achieved by adding flame retardants (such as antimony trioxide).
limitation:
Halogenated: When burned, it produces a large amount of dense smoke and toxic, corrosive hydrogen chloride (HCl) gas.
Limited temperature resistance: The long-term operating temperature is usually 70℃ (standard type) or 90℃ (105℃ for heat-resistant type).
Hardening at low temperatures: Flexibility decreases in low-temperature environments.
Certificates and Conformity
IEC 60227: Polyvinyl chloride insulated cables with rated voltage of 450/750V and below.
IEC 60502: Extruded insulated power cables with rated voltages from 1kV to 30kV.
UL series standards (such as UL 62, UL 83):
Flame retardant test: IEC 60332-1 (single vertical burning).
