• Complies with acid gas emission requirements • Ducab Smokemaster insulation allows of IEC 60754 Part 1 & Part 2 and also complies continuous conductor operating temperatures with Category C of IEC 60332 - 3. up to 90˚C.
• Ducab Smokemaster Armoured Cables
are suitable for a wide range of applications • Maximum conductor temperature allowed including where sections of the cable are under short circuit conditions is 250˚C. underground.
• Low Smoke and Zero Halogen properties, • Higher operating and short circuit no halogen acid gas emissions and reduced temperatures provide opportunity to reduce ignition and fire propagation properties. conductor sizes.
• The cable construction combines XLPE
conductor in sulation with Ducab Smokemaster • All cables have clear identification and marking LSZH beding and outer sheath.
• 90˚C conductor operating temperature
• Independent product testing to provides the opportunity to reduce conductor BS EN 50525-3-41 sizes.
• Approved by Lloyds Register (UK) and BASEC • BASEC Approved (1.5 to 630 sq mm sizes)
