21 Class 2 copper conductor sizes from 1.5 to 1000 mm².
XLPE insulation and ST8 halogen free sheath; no metallic armour.
90°C maximum operating temperature and 250°C short-circuit limit for 5 seconds.
Circular conductors: 4 × OD at OD ≤25 mm, 6 × OD above 25 mm; shaped conductors: 8 × OD.
Separate dimensional, current-capacity and voltage-drop tables for installation planning.
Match the selected size to the circuit load, fault duty and termination capacity.
The electrical tables reference BS 7671:2008 at 90°C conductor and 30°C ambient. Confirm project rules, grouping and installation corrections before final selection.
Specify conductor class, core colour, sheath colour and any UV, oil, hydrocarbon, rodent or termite protection options in the enquiry.
For routes needing mechanical protection, compare the AWA construction below. For fire survival circuits, ask BURY CABLE for the required circuit-integrity evidence.
The dimension table lists Class 2 copper. Class 1 and Class 5 options should be specified separately with BURY CABLE.
Select the column for the actual installation method and cable formation, then apply the required correction factors.
LSZH describes smoke and halogen performance. A fire survival circuit needs a suitable cable and separate circuit-integrity evidence.
Confirm route protection and the complete underground installation design with BURY CABLE before selection; the construction has no armour.
Provide conductor area, length per run, installation method, operating conditions, colours and project fire-performance requirements.
