BTLY 3+1-Core Flexible Mineral-Insulated Fire-Resistant Power Cable, Aluminum Sheath, 0.6/1kV IEC Distribution Cable

BTLY combines copper conductors with an aluminum sheath in this flexible mineral-insulated power cable. The 3+1-core version is intended for power-distribution requirements, giving buyers a defined configuration to carry into a project specification and dimensional drawing.

Copper conductors inside an aluminum sheath

The two metals describe different parts of this BTLY construction: copper belongs to the conductors, and aluminum identifies the sheath. Keep that distinction explicit when comparing cable builds or preparing a technical enquiry. Mineral insulation is another separate construction detail, so a request for this version should identify the conductor system, insulation and outer metal sheath together.

Carry the 3+1 layout into the distribution design

This version has a rated voltage of 0.6/1kV and a 3+1 conductor arrangement. Use the project drawing to establish each conductor’s required section and role for the proposed distribution circuit. The fire-resistant construction should also be considered against the applicable fire-performance specification for that installation, with the particular test reference and selected build kept together during technical review.

Agree the size reference and finished length

The available 50mm2 option helps identify the requested BTLY selection, while the actual conductor cross-sections and physical cable length need to be agreed for the order. Include those dimensions with the core-arrangement drawing so that the proposed cable is described as one complete construction. Keep any project-specific drawing details with the same request before finalising the cable schedule.

For buyers comparing a 3+1 distribution cable, the useful distinction here is the copper conductor system within an aluminum-sheathed mineral-insulated build. A complete specification links those materials to the required layout, dimensions and installation criteria.
