H07V-K

CHARACTERISTICS

I. Conductor and Insulation System

1.Conductor: Flexible stranded copper conductor (Class 5 per IEC 60228), made up of fine copper wires bunched together, offering high flexibility for routing through switchgear, distribution boards, and confined wiring spaces.

2.Insulation: PVC (polyvinyl chloride) insulation, type TI 2 compound, providing reliable dielectric strength along with good resistance to abrasion and general handling during installation.

3.Conductor Sizing: Typically available from 0.5mm² up to 400mm², covering everything from small control wiring to larger panel and switchgear connections.

4.Single-Core Design: As a single-core cable without an outer sheath, it is intended to be installed inside conduit, trunking, or enclosed equipment rather than run exposed, relying on the surrounding installation for mechanical protection.

II. Temperature and Voltage Rating

1.Voltage Rating: Rated at 450/750V, denoted by the "07" in the type designation, suitable for fixed internal wiring in low voltage installations.

2.Conductor Operating Temperature: Rated for continuous operation at 70°C, in line with standard PVC insulation performance, suitable for typical indoor wiring conditions.

3.Standard Classification: The "H" designates a harmonized cable type under CENELEC HD 21, ensuring consistent performance and dimensional standards across European markets.

III. Installation and Application Environment

1.Primary Use Case: Designed for fixed internal wiring inside conduit, trunking, switchboards, distribution panels, and control cabinets, rather than for direct burial, outdoor exposure, or flexible/mobile applications.

2.Indoor Wiring: Commonly used for wiring inside junction boxes, lighting circuits, and internal connections within electrical panels and equipment enclosures.

3.Not for Damp/Wet Locations: As a general-purpose internal wiring cable, it is not intended for direct exposure to moisture, oil, or outdoor weathering — applications requiring wet location performance typically call for a different cable type.

IV. Mechanical and Handling Characteristics

1.Flexibility: The finely stranded conductor (Class 5) gives the cable good flexibility, making it easier to route through tight conduit bends and terminate at closely spaced connection points.

2.Ease of Installation: The single-core, sheath-free construction keeps the cable compact and lightweight, simplifying installation within enclosed wiring systems where multiple conductors need to be run together.

3.Standard Compliance: Manufactured in accordance with IEC 60227 and CENELEC HD 21, ensuring consistent quality and performance recognized across European and IEC-aligned markets.

V. Available Configurations

1.Conductor Sizing: Wide range from 0.5mm² up to 400mm², suitable for both small control circuits and larger power distribution connections within panels.

2.Insulation Color: Available in a range of standard colors to support circuit identification and compliance with local wiring color codes.

3.Application Fit: Well suited to internal panel wiring, control cabinets, and conduit installations where flexibility and ease of termination are priorities over external mechanical or weather protection.
