TROMMELFLEX PUR-HF halogen-free drum reeling cable. Type D12Y11YU11Y. 0.6/1 kV, PUR sheath, water resistant to 50 m, −40 °C flex, IEC 60332-1. 25 N/mm² tensile. Crane and port equipment.
The TROMMELFLEX PUR-HF is a premium halogen-free drum reeling cable designed for fire-safety-critical crane environments including enclosed port facilities, passenger terminals, tunnels, and offshore platforms. The type designation D12Y11YU11Y indicates a polyurethane inner sheath plus polyurethane halogen-free outer sheath construction — both compound layers emit no toxic halogen gases in the event of fire.
PUR construction also delivers permanent water resistance to 50 m depth, making this cable suitable for outdoor port and shipyard equipment subject to rain, wash-down, and flooding without additional protection.

Standard PVC and CR rubber sheaths release hydrochloric acid gas (HCl) when burned — enough to incapacitate workers in enclosed spaces before fire suppression activates. PUR-HF sheaths produce no halogen acids.
HCl gas corrodes electronic equipment and structural steel rapidly after a fire event. Halogen-free cables eliminate this secondary damage — protecting crane drives, PLC panels, and structural steelwork.
Many enclosed public infrastructure projects require halogen-free cables to BS 7622, IEC 60754, or equivalent national standards — this cable meets those requirements without the need for additional fire protection.
Unlike most halogen-free rubber types, the PUR compound provides permanent water resistance — removing the need for separate waterproofing in outdoor crane installations.
