Q: What is the minimum bending radius and operating temperature range for YTKGXFtZnyn?

The minimum bending radius for YTKGXFtZnyn is 12 × OD across its continuous operating temperature range of -30 to +70 °C, ensuring mechanical and dielectric reliability in mining and heavy industrial service.

Q: How are the concentric layers of YTKGXFtZnyn arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Solid Copper Conductors (10×2×0.8 mm) (PN-EN 60228 Class 1 solid annealed bare copper conductors (Ø 0.8 mm)); (02) Low-Capacitance PE Insulation (X) (Solid polyethylene insulation (<55 nF/km) for long-distance mine telephony); (03) Core Wrap & PVC Inner Bedding (Y) (Polyester film tape wrap + extruded black PVC inner bedding sheath); (04) Double Steel Tape Armour (FtZn) (Two helically applied galvanized steel tapes for ≤45° roadway crush protection); (05) Mining Flame-Retardant Sheath (yn) (Grey high-oxygen-index (LOI ≥ 29%) Cat. C flame-retardant PVC jacket).

Q: What factory test certificates are supplied with YTKGXFtZnyn?

Every production drum of YTKGXFtZnyn undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per PN-G-90032 / ZN-TF-39 / IEC 60332-3-24, and is delivered with an EN 10204 3.1 factory test certificate.
