YOTKGtsFoyn (YOTKGtsFoyn SWA Multi-Loose-Tube Mine Shaft Optical Cable) is manufactured in accordance with ZN-TF-115 / EN 60794-1-2 / IEC 60332-3-22 for Optical duty over -40 to +70 °C. Its 5-layer construction comprises Central Strength Member (CSM), Gel-Filled Loose Tubes (6×12F Gts) and EMAG Mining Outer Sheath (yn).

What is the minimum bending radius and operating temperature range for YOTKGtsFoyn?

The minimum bending radius for YOTKGtsFoyn is 15 × OD across its continuous operating temperature range of -40 to +70 °C, ensuring mechanical and dielectric reliability in mining and heavy industrial service.

How are the concentric layers of YOTKGtsFoyn arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Central Strength Member (CSM) (Dielectric Fiber-Reinforced Plastic (FRP) central anti-buckling rod); (02) Gel-Filled Loose Tubes (6×12F Gts) (SZ-stranded PBT tubes (Red/Green marker + Natural tubes) with 12 SM fibres); (03) Water-Blocking Tape & Black Inner Sheath (Water-blocking tape + black flame-retardant PVC inner bedding sheath (Y)); (04) Round Steel Wire Armour (Fo) (Helically applied galvanized steel wires (11–15 kN shaft tensile rating)); (05) EMAG Mining Outer Sheath (yn) (Blue Cat. A bunched-flame-retardant (IEC 60332-3-22) mining PVC jacket).

What factory test certificates are supplied with YOTKGtsFoyn?

Every production drum of YOTKGtsFoyn undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per ZN-TF-115 / EN 60794-1-2 / IEC 60332-3-22, and is delivered with an EN 10204 3.1 factory test certificate.
