TENAX TTS medium voltage drum reeling cable. 3.6/6–12/20 kV, 25 N/mm² dynamic tensile, 180 m/min. EPR super-clean, semiconductor field control, red/stripe sheath. Container crane and fast-cycle equipment.
The TENAX TTS is the premium high-dynamic medium voltage drum reeling cable designed for container cranes, large rubber-tyred gantry (RTG) cranes, and any fast-moving heavy industrial equipment where peak dynamic tensile loads during acceleration and emergency braking significantly exceed the steady-state value. The distinctive red or black-with-yellow-stripe outer sheath immediately identifies TENAX TTS as a high-specification cable on the crane structure.
The TENAX TTS outperforms standard MV reeling cables in tensile load rating — 20 N/mm² continuous and 25 N/mm² peak dynamic — while retaining the same 90 °C conductor temperature, ±50°/m torsional endurance, and EPR super-clean insulation system with semiconductor field control layers.

Emergency stops on fast container cranes generate cable snap loads far exceeding steady-state values. Standard MV reeling cables rated at 15 N/mm² fail at these peak loads — TENAX TTS's 25 N/mm² dynamic rating provides the necessary safety margin.
The distinctive red or black-with-yellow-stripe sheath allows immediate identification of TENAX TTS as an MV cable on the crane structure, reducing the risk of accidental contact during maintenance activities.
The LWL variant integrates multimode or singlemode fibre-optic cores alongside MV power in a single reel cable — enabling high-speed encoder feedback, camera, and automation data on the same drum as the crane drive supply.
