The BURY CABLE BS 6724 1900/3300V range, also expressed as 1.9/3.3kV, is intended for fixed power distribution in buildings, substations, infrastructure and industrial plants. XLPE insulation, an LSZH outer sheath and wire armour provide a construction for projects specifying low-smoke, halogen-free sheathing and mechanical protection.
Typical routes include cable trays, ducts, risers, plant rooms and protected underground systems. Select the conductor material, core arrangement and cable size against the project cable schedule and installation conditions. The listed family construction uses aluminium wire armour (AWA) for single-core cables and galvanised steel wire armour (SWA) for multicore cables.
This page provides an overview of the 1900/3300V range. Use the relevant product specification for dimensions, approximate weight and conductor-form details, and agree the final supplied construction before ordering.

1900/3300V (1.9/3.3kV) cable range for fixed power distribution.
XLPE insulation and an LSZH outer sheath, with final material grades specified for the selected cable.
Single-core AWA and multicore galvanised steel wire armour arrangements.
Copper and aluminium conductor options, subject to the required core configuration and size.
Flame-retardance, halogen-content and smoke-density references listed separately in the technical information.

Start with the required voltage rating. State 1900/3300V or 1.9/3.3kV in the cable schedule and enquiry. Use dimensions and selection data for that voltage-rated construction. The separate 600/1000V range has its own specifications and must not be used as a dimensional or rating substitute.
Specify the conductor and core arrangement. Confirm copper or aluminium, number of cores, cross-sectional area, conductor form and class, core identification and final insulation grade. The general construction table includes several family options; the selected product drawing and quotation should define the exact combination supplied.
Check the electrical design and accessories. Obtain a current-rating assessment for the actual route, together with the required voltage-drop and fault checks. Confirm overall diameter, bending and pulling requirements, glands, terminations, and armour bonding and earthing. This overview does not provide one size range or current rating applicable to every construction.
Agree the environment and delivery details. Provide the installation route, ambient and exposure conditions, total length, drum lengths, sheath colour, test documents, packing and delivery destination. Confirm requirements for outdoor use, ducts, trenches, direct burial, water or chemical exposure. Gallery images show three-core and single-core copper examples; use the approved drawing for the selected cable.

Yes. These are the same voltage values expressed in volts and kilovolts. This page covers the 1900/3300V range; specify the complete rating when requesting a quotation.
The family construction table lists aluminium wire armour for single-core cables and galvanised steel wire armour for multicore cables. Confirm the armour, bonding and earthing arrangement for the selected cable and circuit.
The range includes copper and aluminium conductor options. Their conductor construction, dimensions and selection data must be checked separately. State the required material, number of cores, size, form and class in the enquiry.
Use the dedicated product parameter table for approximate diameter and weight, then confirm final supply dimensions. Request a current-rating assessment for the actual cable construction and installation conditions; this overview does not contain a universal ampacity table.
No. Low-smoke and halogen-free properties, together with the listed flame-retardance references, do not establish a circuit-integrity classification or fire survival duration. Obtain product-specific test evidence where continued operation during fire is required.
Confirm the proposed duct, trench or direct-burial arrangement, moisture conditions and mechanical protection for the selected cable. Suitability depends on the approved supply specification and project installation requirements.
Provide BS 6724, 1900/3300V, conductor material, core quantity, cross-sectional area, armour type, total length and drum lengths. Include installation conditions, core identification, sheath requirements, test documents, packing and delivery destination.
