T/LWB 025-2020 Nominal voltage 1 kV (Um = 1.2 kV) Flexible Mineral Insulated Fire-resistant Cable
Basic Information
Scope
Main technical content: All cables should have an outer sheath. The outer sheath is usually orange. If the manufacturer and the buyer reach an agreement, other colors may be used to adapt to the specific conditions of the cable's use. The outer sheath adopts the sheath compound with the code "ST8" specified in GB/T 12706.1-2008. The outer sheath should be smooth and round on the surface, with a generally consistent color. The cross-section should have no visible bubbles or impurities. The nominal thickness of the outer sheath should comply with the provisions of GB/T 12706.1-2008 for the outer sheath of XLPE insulated cables, with a minimum thickness of not less than 85% of the nominal value plus 0.1 mm. The thickness measurement results should be rounded to one decimal place.
