RT 113 / RT 123 PUR Pitch Control (RT 113 / RT 123 300/500 V (UL/CSA 600 V) Class 6 TMPU PUR High-Torsion (±450°/0.5m) Wind Pitch Control Cable) is manufactured in accordance with DIN VDE 0285 & UL/CSA 600 V RT 113 (Unscreened) / RT 123 (Screened) ±450°/0.5m Pitch Specification for 300/500 V (UL 600 V) wind turbine service over -50 to +90 °C. Its 4-layer construction comprises class 6 ultra-fine bare copper (2-25 cores), special tpe low-temperature core insulation and tmpu halogen-free pur outer sheath (-50 °c).

What is the minimum bending radius and operating temperature range for RT 113 / RT 123 PUR Pitch Control?

The minimum bending radius for RT 113 / RT 123 PUR Pitch Control 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 113 / RT 123 PUR Pitch Control arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Class 6 Ultra-Fine Bare Copper (2-25 Cores) — IEC 60228 Class 6 extra-fine copper strands (0.25–2.5 mm²); (02) Special TPE Low-Temperature Core Insulation — Thermoplastic elastomer insulation remaining supple at -50 °C; (03) Low-Friction Wrap & Screen (RT 113 / RT 123) — Unscreened (RT 113) or tinned copper screen (RT 123) for ±450°/0.5m torsion; (04) TMPU Halogen-Free PUR Outer Sheath (-50 °C) — Oil-, microbe- and abrasion-resistant polyurethane jacket.

What factory test certificates are supplied with RT 113 / RT 123 PUR Pitch Control?

Every production drum of RT 113 / RT 123 PUR Pitch Control undergoes routine conductor DC resistance, AC high-voltage dielectric and dimensional testing per DIN VDE 0285 & UL/CSA 600 V RT 113 (Unscreened) / RT 123 (Screened) ±450°/0.5m Pitch Specification, and is delivered with an EN 10204 3.1 factory test certificate.
