elpar H07V-U (DY) single-core PVC insulated installation cable 4 mm² red — 100 m

elpar H07V-U (DY) single-core PVC insulated installation cable 4 mm² red — 100 m is a fixed-installation conductor designed for indoor electrical wiring and power distribution. The cable features a single solid copper conductor with PVC insulation and a red outer sheath, supplied on a 100 m roll for ease of cutting and installation. It is intended for permanent installation in dry, protected environments where a single insulated conductor is required for connection, phase identification, or internal routing.

Advantages

This single-core H07V-U cable provides a compact, reliable conductor for fixed installations. The 4 mm² copper core ensures good current-carrying capacity for many domestic and light commercial circuits, while the PVC insulation offers mechanical protection and electrical isolation. Supplied in a bright red colour, the cable simplifies identification for phase wiring or signalling purposes and the 100 m roll format reduces the need for frequent joins during runs.

Suitable for (tasks / use cases)

• Fixed internal electrical installations in domestic buildings
• Phase conductors and single-core runs inside distribution boards
• Power routing to appliances and lighting circuits in protected environments
• Wiring of junction boxes and short connection runs where a single insulated conductor is required

When it may not be suitable

This cable is intended for fixed indoor use in dry and protected locations and is not suitable for exposed outdoor installation, direct burial, or use in permanently damp or wet environments. It is a solid single-core conductor and therefore less flexible than multi-core or stranded cables, which can make routing through tight conduits or frequent bending points difficult.

Key specifications

• Conductor: single solid copper core
• Conductor cross-section: 4 mm²
• Insulation material: PVC (polyvinyl chloride)
• Outer colour: red
• Length: 100 m roll
• Application type: fixed internal electrical installations

How to use

Measure and cut the required length from the 100 m roll, ensuring power is switched off at the relevant circuit breaker before any work. Strip the PVC insulation to expose the copper conductor only where connections are required, and make terminations in accordance with applicable wiring regulations and recommended torque values for terminals. Secure the cable within ducts, conduits, or trunking where appropriate and avoid excessive bending radii to prevent conductor damage. If unsure about circuit design or connection, consult a qualified electrician.

What to consider before purchase

• Confirm suitability for indoor, dry fixed installations rather than outdoor or buried use
• Check that a single solid 4 mm² conductor meets the required current-carrying capacity for your circuit
• Ensure the red colour meets your phase identification or colour-coding scheme
• Verify routing space and bending requirements, since solid core is less flexible than stranded alternatives

Usage recommendations

Apply standard installation practices: switch off power before cutting or terminating, use proper stripping tools to avoid damaging the conductor, respect minimum bending radii, and secure the cable to prevent mechanical strain. For circuits approaching the conductor's current capacity or for installations with special environmental conditions, use a cable type specified for those conditions or consult a certified electrician.
