What governing standard and construction define YHKGSYFoyn (YHKGSYFoyn 300/500 V SWA Mine Shaft Ex-i Sensor Cable)?

YHKGSYFoyn (YHKGSYFoyn 300/500 V SWA Mine Shaft Ex-i Sensor Cable) is manufactured in accordance with WT-TK-25 / TI EMAG / IEC 60332-3-24 for 300/500 V duty over -30 to +70 °C. Its 5-layer construction comprises Screened Signal Cores (6×1.5 mm²), Protective Earth Core (+1×1.5 żo) and Ex-i Blue Outer Sheath (yn).

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

The minimum bending radius for YHKGSYFoyn 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.

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

From inside to outside, the construction sequence is: (01) Screened Signal Cores (6×1.5 mm²) (Class 1 solid bare copper + numbered PVC + individual tinned Cu braid (H)); (02) Protective Earth Core (+1×1.5 żo) (Class 1 solid bare copper conductor with green/yellow PVC in outer layer); (03) PVC Inner Bedding Sheath (Y) (Polyester tape wrap + extruded grey PVC inner cushioning sheath); (04) Round Steel Wire Armour (Fo) (Galvanized round steel wire armour for ≤90° vertical mine shafts); (05) Ex-i Blue Outer Sheath (yn) (RAL 5015 intrinsically safe high-LOI (LOI ≥ 29%) Cat. C mining PVC jacket).

What factory test certificates are supplied with YHKGSYFoyn?

Every production drum of YHKGSYFoyn undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per WT-TK-25 / TI EMAG / IEC 60332-3-24, and is delivered with an EN 10204 3.1 factory test certificate.
