Overview

Low-voltage aluminum busway

LVA is our most widely used low-voltage system: an aluminum busway for main feeders, risers and plug-in distribution in commercial, residential and industrial buildings. Pre-sealed plug-in outlets let you add loads as the building grows.

Best for: Default choice for low-voltage feeders and risers

Key features

  • Sandwich construction

    Flat-laid conductors in a 125 mm wide housing reduce heat build-up and save space.

  • Dual-layer housing

    Maximizes heat dissipation and supports up to IP66 protection.

  • Plug-in flexibility

    Pre-sealed, dust-proof outlets ready for future load expansions.

  • Halogen-free insulation

    Class H epoxy or polyester resin: flame-retardant and mechanically robust.

  • Bridge-type joint

    ±8 mm flexibility, Belleville spring washers and phase-error-proof assembly.

  • Compact tap-off boxes

    Up to 400 A with breakers or fuses and optional locks. SCADA-ready temperature monitoring available.

Specialist product · GM-Z

Are you looking for medium-voltage busway?

GM-Z is a cast-resin busway built for medium-voltage power: typically the link between generators, transformers and switchgear in power plants and large industrial sites.

It is engineered and quoted project by project. Most commercial and industrial buildings need a low-voltage system such as LVA or GM instead.
