1.0mm2 Solid Copper Conductor Annealed 18 Awg Bare Copper Wire

Performance Highlights

Electrical Performance

Rated Voltage 450/750 V — Suitable for 220/380 V single-phase and three-phase distribution systems, as well as low-voltage control and signaling circuits.
Low Conductor Resistance — Maximum DC resistance at 20 °C of ≤ 18.1 Ω/km, ensuring minimal voltage drop and efficient power transmission over typical building run lengths.
Excellent Dielectric Strength — Withstands 2000 V AC for 5 minutes without breakdown, providing a robust safety margin above normal operating voltage.
Stable Insulation Resistance — Maintains a minimum insulation resistance of ≥ 0.010 MΩ·km at 70 °C, preventing leakage current even under sustained load conditions.

Thermal & Current-Carrying Capability

70 °C Continuous Operating Temperature — The PVC insulation is formulated for long-term thermal stability at 70 °C ambient-rated service, with a short-circuit withstand capability of up to 160 °C for 5 seconds.
Reliable Ampacity — Delivers approximately 14–15 A in free air and ~11 A when installed in conduit (30 °C ambient), making it ideal for lighting branch circuits, small appliance outlets, and control wiring.
Controlled Thermal Aging — The PVC compound exhibits low thermal deformation and high resistance to embrittlement over decades of service life.

Mechanical Durability

Solid Copper Conductor (Class 1) — 1.13 mm diameter annealed copper rod delivers high tensile strength and dimensional stability. The solid construction resists stretching during pulling and maintains secure terminations under screw-clamp connections.
Uniform Insulation Extrusion — 0.6 mm nominal PVC wall thickness is applied via precision extrusion, producing a smooth, concentric profile with an average overall diameter not exceeding 2.8 mm — compact enough for dense conduit fills.
Good Flexibility for Installation — While solid, the 1.0 mm² gauge offers manageable bending characteristics with a minimum bend radius of 4× diameter (~11 mm), suitable for standard conduit bends and panel routing.
Abrasion & Impact Resistance — The PVC jacket provides effective protection against minor mechanical abrasion, crushing, and impact when installed in conduit or trunking.

Safety Characteristics

Flame Retardant — Passes GB/T 18380.1 single-cable vertical flame test, self-extinguishing once the ignition source is removed, limiting flame spread along the cable length.
Electrical Isolation — High-quality PVC formulation ensures consistent dielectric properties, protecting against accidental contact and short circuits.
Color-Coded Identification — Available in Red, Black, Blue, Yellow/Green (earth), White, Brown, Grey, and Orange for intuitive phase, neutral, and protective conductor identification per regional wiring codes.

Environmental & Chemical Resistance

Moisture Tolerance — Suitable for dry to damp locations (not wet or submerged). Performs reliably in typical indoor humidity conditions.
Chemical Stability — Resistant to common household and industrial chemicals including mild acids, alkalis, oils, and solvents at ambient temperatures.
UV Limitation — Not rated for prolonged direct sunlight exposure; outdoor or rooftop runs require UV-protective conduit or raceway.
Service Life — Expected service life of 25+ years under normal indoor installation conditions with proper derating.

Quality Assurance

Every production batch undergoes in-process and final inspection covering:

Conductor resistance measurement
Insulation thickness and concentricity verification
High-voltage withstand test (spark test or immersion)
Flame retardancy sampling
Dimensional and visual inspection

Test reports and Certificate of Compliance (CoC) are available upon request, referencing batch number and manufacturing date.

Summary

The BV 1.0 mm² / 18 AWG building wire represents the industry-standard choice for general-purpose fixed electrical wiring where cost-effectiveness, proven safety, and regulatory compliance are priorities. It combines a low-resistance solid copper core with durable PVC insulation to deliver stable, maintenance-free performance across the full service life of a building's electrical infrastructure. For projects demanding enhanced fire safety, low-smoke, or higher temperature ratings, the same manufacturer offers direct upgrade paths within the WDZ, NH, and BYJ product families.
