87 construction entries covering power and multicore control configurations.
Two-, three- and four-core power sizes from 1.5 to 400 mm².
Three-core plus earth variants; 5–61 core entries in the listed 1.5 and 2.5 mm² sizes.
Class 2 copper as listed; alternative conductor classes are optional.
90°C maximum operation; 250°C short circuit for 5 seconds.
Select the exact core count and earth-conductor size. Confirm colours or numbered cores and the circuit function.
Match bending space to the circular or shaped conductor rule and selected cable diameter shown below.
Electrical tables cite BS 7671:2008 for two-core and three-/four-core circuits. Request application-specific ratings for five-core and larger multicore configurations.
Confirm grouping, ambient conditions and route protection. Specify optional UV, oil, hydrocarbon, rodent or termite protection when needed.
Use the individual construction rows. The small multicore entries use 1.5 or 2.5 mm²; the power-cable sections have their own ranges.
The colour table specifies colours for up to five cores and black cores with white numerals above five cores; confirm the required scheme.
Request ratings based on loaded cores, grouping and duty. The displayed electrical tables refer to the stated two-, three- and four-core circuits.
Choose additional mechanical protection where the route design requires it; compare the related SWA LSZH product.
Provide core arrangement, area, lengths, load, installation method and smoke, halogen and sheath requirements.
