Single-core LgY (H07V-K) electrical wire with a 1 x 1.5 mm² cross-section and white PVC insulation. This single flexible copper conductor is intended for fixed internal electrical installations and lighting circuits where a single live or neutral conductor is required. The cable meets the construction style of H07V-K class—thin-stranded copper for easier routing in conduits and junction boxes while retaining the mechanical properties suitable for indoor, dry environments.
Advantages
The LgY 1x1.5 H07V-K wire combines a compact single-core design with flexible, fine-stranded copper to facilitate bending and connection in confined spaces. White PVC insulation provides visible colour coding for circuits and standard protection against mechanical wear in typical indoor conditions. The conductor size of 1.5 mm² balances current-carrying capacity and ease of handling for lighting and small appliance circuits.
Suitable for
- Fixed indoor wiring in dry rooms
- Lighting circuits and switches
- Connection of appliances or devices that require a single conductor
- Routing through conduits, trunking, and junction boxes
When it may not be suitable
This cable is not designed for outdoor use, burial in ground, or exposure to moisture, chemicals, or direct sunlight; it should not be used where heat, oil, or mechanical abrasion exceed normal indoor installation conditions. It is also not appropriate for applications requiring multi-core cable assemblies, earthing conductors, or flexible cord usage that needs continuous movement.
Key specifications
- Conductor: flexible copper, fine-stranded
- Number of cores: 1
- Cross-sectional area: 1.5 mm²
- Insulation material: PVC (white)
- Design standard: H07V-K class construction (single-core, fixed installation)
- Typical application environment: indoor, dry locations
How to use
Strip an appropriate length of the white PVC insulation without nicking the copper strands, then terminate the conductor in the required connector, screw terminal, or crimp ferrule to ensure a reliable electrical and mechanical connection. Route the wire through conduits or trunking as needed, avoiding sharp bends and securing at regular intervals with clips or cable ties designed for single-core wiring. Ensure the circuit is de-energised before working and that connections comply with applicable electrical codes and ampacity limits for 1.5 mm² conductors.
What to consider before purchase
- Confirm that a single-core 1.5 mm² conductor is suitable for the intended circuit load and protective device.
- Verify the installation environment is dry and indoors; select different cable types for outdoor, wet, or high-temperature conditions.
- Plan terminations and use appropriate ferrules or connectors for fine-stranded conductors to prevent strand spread.
Usage recommendations
Use the LgY 1x1.5 H07V-K wire for fixed lighting and single-conductor indoor connections where mechanical stress is moderate. For reliable terminations with fine-stranded copper, fit appropriate ferrules or crimped lugs and follow local electrical regulations for conductor routing and protection.
