Voltage Rating: The cable is designed for low-voltage (LV) building grids, with a rated voltage of 300/500V AC (phase-to-ground/phase-to-phase). This aligns with global LV standards: 230V single-phase (Europe, Asia, Australia) and 120V/240V split-phase (North America). The 300/500V rating provides a 2x safety margin against typical operating voltages, protecting against transient spikes (e.g., from lightning or grid fluctuations) that could damage insulation. Under IEC 60227 testing, the cable withstands 2000V AC for 1 minute without dielectric breakdown—ensuring no electrical leakage even in high-humidity spaces like bathrooms.
Current-Carrying Capacity: Each cross-sectional area is optimized for specific load demands, with ratings derived from IEC 60287 (calculating capacity based on Conductor Material, insulation thermal resistance, and ambient temperature). Key ratings (at 30°C ambient, open-air installation):
1.5mm²: 16A (powers lighting circuits, small appliances like phone chargers or desk lamps)
2.5mm²: 24A (ideal for wall outlets in living rooms, bedrooms, or offices)
4mm²: 32A (handles kitchen outlets for blenders, toasters, or small refrigerators)
6mm²: 40A (supports HVAC systems, electric water heaters, or garage outlets)
10mm²: 50A (main Feeder Cables from electrical panels to high-power zones)
16mm²: 63A (heavy-duty feeder lines for light industrial equipment or multi-unit apartment buildings)
DC Resistance: The solid copper conductor ensures low resistance, meeting IEC 60228 Class 1 (solid conductors) standards. At 20°C:
1.5mm²: ≤12.1Ω/km
2.5mm²: ≤7.41Ω/km
6mm²: ≤3.08Ω/km
16mm²: ≤1.15Ω/km
Conductor Diameter: The solid copper conductor’s diameter varies by cross-section, adhering to IEC 60228:
1.5mm²: 1.38mm (diameter = √(4×1.5/π) ≈1.38mm)
2.5mm²: 1.78mm
6mm²: 2.76mm
16mm²: 4.51mm
Insulation Thickness: PVC insulation has a nominal thickness of 0.8mm for 1.5mm²–6mm² cables and 1.0mm for 10mm²–16mm² (to accommodate higher voltages). Thickness tolerance is ±0.1mm, validated via IEC 60811:
Needle penetration test: Withstands 10N force (15N for 10mm²–16mm²) without conductor contact, preventing damage from accidental punctures during installation.
Thickness uniformity: Measured at 8 points per meter using a laser micrometer—no point below 80% of nominal thickness.
Weight and Outer Diameter (OD): A 100-meter length of cable weighs:
1.5mm²: ~1.8kg
2.5mm²: ~3.0kg
6mm²: ~7.2kg
16mm²: ~19.2kg
Mechanical Strength: Key properties meet IEC 60227:
Tensile strength: ≥15MPa (PVC insulation)
Elongation at break: ≥150% (insulation), ensuring the cable can stretch slightly during installation without cracking.
Minimum bending radius: 10×OD for fixed installation (e.g., 30mm for 1.5mm² cable), allowing easy routing around corners in wall cavities.
Purity and Sourcing: The conductor uses 99.95% pure electrolytic copper, sourced from certified suppliers meeting GB/T 467 (Chinese standard) and ASTM B170 (US standard). This purity ensures minimal impurities (iron ≤0.003%, oxygen ≤0.03%), which can increase resistance and cause hot spots.
Solid Structure Advantages: Unlike Stranded Conductors (used in Flexible Cables), the solid design offers:
Mechanical Stability: Ideal for permanent, fixed installations (wall cavities, ceiling joists) where the cable remains stationary—no strand separation or fatigue over time.
Easy Termination: Inserts cleanly into terminal blocks, wire nuts, and light switches, reducing installation time by 20% compared to Stranded Conductors (which require twisting to maintain shape).
Consistent Conductivity: No air gaps between strands, ensuring uniform current distribution and lower resistance.
Corrosion Resistance: Copper forms a stable oxide layer (CuO) that protects the conductor from moisture and mild chemicals—critical for use in bathrooms, kitchens, or basements. Unlike aluminum, copper does not require anti-oxidation compounds to maintain connections, simplifying maintenance.
Formulation: PVC insulation is a blend of:
SG-5 PVC resin (high molecular weight, for durability and impact resistance).
Phthalate-free plasticizers (DINP, meeting RoHS standards) to enhance Flexibility—prevents the insulation from becoming brittle in cold temperatures (-15°C).
Flame retardants (antimony trioxide + aluminum hydroxide, 25% by weight) to meet UL 94 V-0 and IEC 60332-1 standards.
Stabilizers (calcium-zinc-based) to prevent degradation from heat and UV exposure (common in attic wiring).
Performance Benefits:
Temperature Range: -15°C to 70°C, covering most indoor building environments—from cool basements (-5°C) to warm attics (60°C).
Moisture Resistance: Water absorption ≤0.5% after 24-hour immersion (IEC 60811-104), preventing insulation breakdown in humid spaces like laundry rooms.
Chemical Resistance: Resistant to common household chemicals (e.g., ammonia, bleach, paint thinners) and oils—suitable for kitchens or workshops.
Cost Efficiency: PVC is 30–40% cheaper than premium insulations like XLPE, a key factor in the cable’s competitive price point.

Lighting Circuits: 1.5mm² cables power LED downlights, ceiling fans, and wall sconces. A single 16A circuit (using 1.5mm² cable) can support up to 20 LED downlights (10W each, total 200W = 0.87A at 230V), covering a standard 3-bedroom house. The solid conductor’s easy termination simplifies connecting to light switches and dimmers, while the PVC insulation’s flame retardancy reduces fire risk in ceiling cavities.
Wall Outlets: 2.5mm² cables serve living room, bedroom, and office outlets. A 24A circuit (2.5mm²) can power 8–10 outlets, supporting laptops (60W), smartphones (10W), and small appliances (200W) without overloading. In kitchens, 4mm² cables are used for countertop outlets, handling higher loads from blenders (500W) or toasters (800W).
Main Feeder Lines: 6mm²–16mm² cables connect the main electrical panel to high-power zones:
6mm²: Powers electric water heaters (2kW) or HVAC systems (3kW).
10mm²: Feeds garage outlets for electric tools (1.5kW) or EV chargers (3.7kW).
16mm²: Serves multi-unit apartments, distributing power to 2–3 residential units from a central panel.
Renovations: The cable is ideal for upgrading outdated wiring (e.g., replacing 1mm² Aluminum Cables in 1970s homes). Its small OD (3.0mm–6.5mm) fits through existing wall channels, avoiding the need for extensive drywall removal—reducing renovation costs by 30%.
Offices: 2.5mm² cables power workstations (computers, printers, desk lamps) and 1.5mm² for lighting. The single core structure allows flexible circuit design—cables can be routed under floors or through ceiling tiles to accommodate open-plan layouts. In meeting rooms, 4mm² cables support AV equipment (projectors, sound systems) with higher power demands.
Retail Stores: 2.5mm² cables serve POS systems, display lighting, and small appliances (e.g., coffee machines in customer lounges). The color-coded insulation simplifies reconfiguring circuits when rearranging product displays—electricians can quickly identify phase/neutral/earth without testing.
Restaurants: 4mm² cables are used for kitchen outlets (commercial blenders, microwaves) and 6mm² for refrigerators or small freezers. PVC insulation’s chemical resistance withstands spills of oils, sauces, or cleaning agents, ensuring durability in high-traffic kitchen environments.
Workshops: 4mm²–6mm² cables power hand tools (drills, grinders) and 1.5mm² for task lighting. The solid conductor’s mechanical stability resists vibration from machinery, preventing loose connections that could cause downtime. In metalworking shops, the cable’s flame retardancy reduces fire risk from sparks.
Small Warehouses: 6mm²–10mm² cables supply power to pallet jacks (2.5kW), fans, and inventory scanners. The cable’s low resistance ensures minimal voltage drop over long runs (e.g., 50m of 6mm² cable loses just 0.154Ω, maintaining stable power for equipment).
Manufacturing Lines: 10mm²–16mm² cables power light assembly equipment (e.g., small conveyors, packaging machines) with 3–5kW loads. Compliance with IEC 60227 ensures the cable meets industrial safety standards, while its competitive price fits small business budgets.
Schools: 1.5mm² cables power classroom lighting and 2.5mm² for outlets (laptops, projectors). The flame-retardant PVC insulation meets strict fire safety codes for public spaces, while the solid conductor’s durability withstands occasional rough handling (e.g., moving classroom furniture).
Clinics: 2.5mm² cables serve exam rooms (medical devices like blood pressure monitors, 100W) and 4mm² for small medical refrigerators (200W). PVC insulation’s moisture resistance is critical in sterile rooms, where frequent cleaning with water-based disinfectants is common.
Community Centers: 6mm² cables power HVAC systems and event spaces (sound systems, stage lighting), while 1.5mm² handles general lighting. The cable’s wide cross-sectional range (1.5mm²–16mm²) allows a single product to meet all wiring needs, simplifying procurement for facility managers.
Copper Melting and Casting: 99.95% pure electrolytic copper cathodes are melted in a induction furnace (1100°C) and cast into 8mm-diameter solid rods. The casting process uses a continuous casting machine to ensure uniform density—voids or impurities in the rod would lead to conductor defects.
Wire Drawing: Copper rods are drawn through a series of diamond dies (reducing diameter by 10–15% per pass) to form solid conductors of the desired cross-section. For example:
8mm rod → 4.51mm (16mm²) → 2.76mm (6mm²) → 1.78mm (2.5mm²) → 1.38mm (1.5mm²)
Annealing: Drawn conductors are passed through a continuous annealing furnace (nitrogen atmosphere, 350–400°C) to soften the copper—reducing tensile strength from 300MPa (after drawing) to 200MPa and increasing elongation from 5% to 25%. Annealing ensures the conductor can bend without cracking during installation. A sample of each batch is tested for conductivity (must be ≥99% IACS) and tensile strength (≥200MPa).
PVC Compound Preparation: PVC resin (SG-5), plasticizers (DINP), flame retardants (antimony trioxide + aluminum hydroxide), and stabilizers (calcium-zinc) are mixed in a twin-screw extruder (160–180°C) to form a homogeneous melt. The melt is pelletized using a water-cooled pelletizer and dried at 80°C for 4 hours to reduce moisture content to ≤0.05%—critical for preventing bubble formation in the insulation during extrusion. Each batch of PVC compound is tested for flame retardancy (UL 94 V-0) and flexibility (-15°C cold bend test) before use.
Extrusion Process: The annealed solid copper conductor is fed into a 45mm single-screw extruder, where the dried PVC pellets are melted (170–190°C) and extruded through a crosshead die. The die is custom-designed for each cross-sectional area:
For 1.5mm²–6mm² cables: Die gap of 0.8mm to achieve nominal insulation thickness.
For 10mm²–16mm² cables: Die gap of 1.0mm to accommodate higher voltage demands.
Color-Coding Application: After insulation extrusion, the cable passes through a color-marking unit for regional compliance. Pigments are injected into the PVC melt during extrusion (for solid-color insulation) or applied as a thin outer layer (for striped insulation, e.g., green-yellow Earth Cables). Color consistency is monitored using a spectrophotometer, ensuring compliance with regional standards (e.g., EN 60446 for Europe).
Electrical Tests:
Dielectric Strength Test: Cables are submerged in 23°C deionized water for 24 hours to simulate humid conditions, then subjected to 2000V AC (conductor-to-water) for 1 minute. No breakdown or leakage current exceeding 10μA is allowed—ensuring insulation integrity.
Insulation Resistance Test: Using a 1000V megohmmeter, insulation resistance between the conductor and a copper foil wrapped around the insulation is measured. Minimum resistance is 100MΩ/km at 20°C—preventing current leakage that could cause shocks or fires.
Conductor Resistance Test: A micro-ohmmeter measures DC resistance of the solid copper conductor. For 2.5mm² cable, resistance must be ≤7.41Ω/km at 20°C—validating conductivity and minimizing energy loss.
Mechanical Tests:
Tensile and Elongation Test: Insulation samples (100mm length) are pulled at 50mm/min using a universal testing machine. PVC insulation must achieve ≥15MPa tensile strength and ≥150% elongation at break—ensuring durability during installation.
Cold Bend Test: Cables are cooled to -15°C for 4 hours, then bent around a mandrel (10×cable OD) 10 times. No cracks in the insulation or conductor damage are allowed—critical for cold-climate installations.
Abrasion Test: A 500g weight is applied to a sandpaper strip (P120 grit) pressed against the cable, which is moved back and forth for 100 cycles. Insulation thickness loss must be ≤20% of nominal—preventing damage from rough wall cavities or conduit.
Flame and Environmental Tests:
Vertical Flame Test (UL 94 V-0/IEC 60332-1): A 1kW propane flame is applied to the cable for 10 seconds, then removed. The cable must self-extinguish within 10 seconds, with no flaming drips and no flame spread to the top 50mm—reducing fire risk in enclosed spaces.
Heat Shock Test: Cables are heated to 100°C for 1 hour, then immediately quenched in 23°C water. No insulation cracking or delamination is allowed—ensuring stability under temperature fluctuations (e.g., attic heat).
Chemical Resistance Test: Samples are immersed in 10% sodium hydroxide (simulating cleaning agents) and 10% hydrochloric acid (simulating industrial fumes) for 24 hours. Insulation weight and thickness change must be ≤5%—validating durability in harsh environments.
Precision Cutting: Tested cables are pulled into a cutting machine with a laser length counter (accuracy ±1mm). Standard lengths include 50m, 100m, and 200m—optimized for retail (50m) and construction (100m/200m) needs. Custom lengths (e.g., 30m for small renovations) are available upon request, with a 1% length tolerance.
Spooling: Cables are wound onto cardboard or plastic spools using a tension-controlled spooling machine. Spool specifications vary by cable size:
