Tri-Rated H05V2-K / H07V2-K Cable

What is Tri-Rated H05V2-K / H07V2-K Cable?

The Tri-Rated H05V2-K / H07V2-K Cable is a single-core, flexible PVC insulated switchgear panel wire recognized globally for meeting three major international standards simultaneously: British Standard BS 6231 Type CK, American Standard UL Style 1015 (UL Subj. 758), and Canadian Standard CSA C22.2 No. 210. Commonly referred to as panel wire or tri-rated cable, it functions as internal wiring for control panels, motor starters, rectifier assemblies, and electrical instrumentation where international compliance and heat resistance are essential.

By integrating British, North American, and European harmonised specifications into a single product line, Tri-Rated wire eliminates the need for switchgear manufacturers to maintain separate inventories for European and North American markets. The cable utilizes Class 5 fine-stranded plain copper conductors combined with a special heat-stabilised PVC compound rated up to +105°C (UL/CSA) and +90°C (BS 6231), delivering superior flexibility, flame retardancy per IEC/EN 60332-1-2, and long-term dielectric performance inside high-density control cabinets.

Applications

Tri-Rated flexible panel wires are engineered for fixed and flexible internal wiring in power distribution and automation enclosures across worldwide markets:

• Power Switchgear & Control Cabinets: Internal interconnecting circuits in low-voltage switchgear, relay cabinets, instrumentation consoles, and distribution boards.
• Industrial Motor Starters & Drives: Wiring for soft starters, variable frequency drive (VFD) auxiliary connections, and motor control centers (MCC).
• Rectifiers & Power Electronic Equipment: Power conversion cabinets, transformer links, uninterrupted power supplies (UPS), and industrial battery systems.
• International Export Machinery: Standardized wiring for industrial tooling machines and automated production lines destined for the UK, Europe, the United States, and Canada.

Specifications & Dimensions

Huadong Cable Group manufactures the complete cross-sectional range of Tri-Rated panel wires from 0.5mm² (approx. 21 AWG) up to 240mm² (approx. 450 MCM). Operating at voltage ratings of 0.6/1kV (UL, CSA, BS 6231), 300/500V (H05V2-K for 0.5mm² to 1.0mm²), and 450/750V (H07V2-K for 1.5mm² and above), the series supports maximum operating temperatures of +105°C (UL/CSA) and +90°C (BS 6231), extending down to -40°C for fixed installations. Nominal overall cable diameters range from 2.7mm (0.5mm²) to 24.4mm (240mm²) with nominal weights spanning 11 kg/km to 2,381 kg/km. The construction supports free-air current ratings from 11A up to 595A and maintains maximum conductor DC resistance values at 20°C strictly compliant with EN 60228 (from 39.0 Ω/km at 0.5mm² down to 0.0801 Ω/km at 240mm²) under a compact minimum bending radius of 6 times the overall cable diameter.

Frequently Asked Questions

Q: Why is this cable called “Tri-Rated” wire?
A: The designation “Tri-Rated” stems from its triple accreditation under three distinct international standards bodies: British Standards (BS 6231 Type CK), Underwriters Laboratories (UL Style 1015), and the Canadian Standards Association (CSA C22.2 No. 210).

Q: What is the difference between the H05V2-K and H07V2-K designations?
A: Under European standard BS EN 50525-2-31, conductor cross-sections between 0.5mm² and 1.0mm² are harmonised as H05V2-K with a voltage rating of 300/500V, whereas sizes 1.5mm² and above are designated as H07V2-K with a voltage rating of 450/750V.

Q: Can Tri-Rated cables be connected to standard terminal accessories rated at 70°C?
A: If connecting Tri-Rated cable to terminals or accessories rated only for 70°C, appropriate current de-rating factors must be applied or high-temperature terminals rated for the conductor’s 90°C/105°C operating temperature must be specified.

Q: What commercial payment terms does Huadong Cable accept for international orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
