What governing standard and construction define RT 114 / RT 116 Torsion & De-Icing (RT 114 / RT 116 300/500 V – 0.6/1 kV (UL 600 V) Class 6 PUR/SCEM Wind Torsion & Blade Trace-Heating Cable)?
RT 114 / RT 116 Torsion & De-Icing (RT 114 / RT 116 300/500 V – 0.6/1 kV (UL 600 V) Class 6 PUR/SCEM Wind Torsion & Blade Trace-Heating Cable) is manufactured in accordance with DIN VDE 0285 & UL 600 V RT 114 / RT 116 (-50 °C, ±150°/m) Wind Torsion & De-Icing Specification for 300/500 V – 0.6/1 kV wind turbine service over -50 to +90 °C. Its 3-layer construction comprises class 6 extra-fine bare copper (2–40 cores), special tpe / cross-linked elastomer insulation and pur / scem cold-resistant jacket (-50 °c).
What is the minimum bending radius and operating temperature range for RT 114 / RT 116 Torsion & De-Icing?
The minimum bending radius for RT 114 / RT 116 Torsion & De-Icing is 5 × OD across its continuous operating temperature range of -50 to +90 °C, ensuring mechanical torsion resistance and dielectric reliability in wind turbine nacelles, hubs and towers.
How are the concentric layers of RT 114 / RT 116 Torsion & De-Icing arranged from inside to outside?
From inside to outside, the construction sequence is: (01) Class 6 Extra-Fine Bare Copper (2–40 Cores) — Ultra-flexible Class 6 copper conductors for continuous torsion; (02) Special TPE / Cross-Linked Elastomer Insulation — Rated 300/500 V, 600 V and 0.6/1 KV for control & trace heating; (03) PUR / SCEM Cold-Resistant Jacket (-50 °C) — Oil- and abrasion-resistant outer sheath rated ±150°/m torsion.
What factory test certificates are supplied with RT 114 / RT 116 Torsion & De-Icing?
Every production drum of RT 114 / RT 116 Torsion & De-Icing undergoes routine conductor DC resistance, AC high-voltage dielectric and dimensional testing per DIN VDE 0285 & UL 600 V RT 114 / RT 116 (-50 °C, ±150°/m) Wind Torsion & De-Icing Specification, and is delivered with an EN 10204 3.1 factory test certificate.
