Nexans H07V-U

Application

Nexans H07V-U is intended for protected fixed electrical installations in dry locations for general power distribution circuits (excluding fire safety circuits), including:

• Residential buildings (single-family and multi-dwelling): final circuits for lighting, socket outlets, electric heating and ventilation systems (VMC), as well as wiring of distribution boards.
• Offices and commercial buildings: lighting and control circuits up to 1000 V AC or 750 V DC to earth.

Note

• For installations requiring enhanced fire performance, use H07Z1-U/R/K halogen-free conductors.
• For fire safety circuits (fire detection and alarm systems, emergency lighting, smoke extraction systems, etc.), use CR1-C1 cable.

Installation

Permitted laying options:

• In free air on insulating supports, in dry locations
• In mouldings, skirting trunking, conduits, ducts or cable trunking systems
• In conduits (surface-mounted or concealed in dry walls)
• Internal wiring of electrical panels, switchboards and enclosures

Not suitable for:

• Direct outdoor installation – PVC insulation is not resistant to UV radiation or weathering
• Damp, wet or flooded locations – moisture resistance limited to AD1 classification (protection against condensation only)
• Direct burial without additional mechanical protection
• Mobile applications or installations subject to repeated flexing – use H07V-K (Class 5) or H07Z-K instead
• Fire safety circuits (fire detection and alarm systems, emergency lighting, smoke extraction systems, etc.) – use CR1-C1 cable

Installation parameters

• Minimum installation temperature: -5 °C
• Minimum bending radius: 4 × overall diameter
