Specifications

Conductors

Material:High-purity annealed copper, compliant with ASTM B-3/B-8 standards, ensuring low resistance and superior conductivity.

Construction:Fine-stranded, multi-conductor design (Class 5 or 6 stranding) for enhanced flexibility and bend resistance.

Coating:Optional tin-plated finish for improved corrosion resistance, ideal for humid or chemically aggressive environments.

Separator

Function:A halogen-free polyester tape or mica barrier layer may be included between the conductor and insulation for mechanical protection and electrical stability.

Material:Halogen-free materials ensure thermal and dielectric reliability under high temperatures.

Voltage Rating

Rated Voltage:300V or 600V, compliant with UL standards for low-voltage power and control systems.

Applications:Suitable for AC/DC circuits in industrial machinery, building wiring, and automation systems.

Insulation & Jacket Materials

Insulation:Cross-linked polyolefin (XLPO) or LSZH (Low Smoke Zero Halogen) thermoplastic for high dielectric strength and heat resistance.

Jacket:Halogen-free thermoplastic elastomer (TPE) or polyolefin, delivering mechanical durability and flame retardancy.

Key Features

Flame Retardant:Passes UL VW-1 vertical flame test.

Eco-Friendly:Free from halogens (Cl, Br), lead, and cadmium; complies with RoHS and REACH regulations.

Resistance Properties

Conductor DC Resistance:Meets UL 1581 standards (e.g., ≤5.21 Ω/km for 20 AWG at 20°C).

Insulation Resistance:≥500 MΩ·km at 20°C (tested at 500V DC).

Temperature Range

Continuous Operation:Rated for 90°C.

Operating Range:-40°C to +105°C, resistant to thermal cycling in harsh environments.

Short-Circuit Tolerance:Withstands +250°C for up to 5 seconds (per UL 1581).

Certification:Passes UL long-term aging tests (e.g., UL 1581 Section 50).
