YHKGSLYkonoynzo-P (YHKGSLYkonoynzo-P 300/500 V Ex-i Methane Monitoring Cable) is manufactured in accordance with WT-TK-24 / TI EMAG / IEC 60332-3-24 for 300/500 V duty over -30 to +70 °C. Its 5-layer construction comprises Screened Pairs (4×2×1.0 mm² -P), Protective Earth Core (+1×1.0 żo) and Ex-i Blue Outer Sheath (yn).

What is the minimum bending radius and operating temperature range for YHKGSLYkonoynzo-P?

The minimum bending radius for YHKGSLYkonoynzo-P is 10 × 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 YHKGSLYkonoynzo-P arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Screened Pairs (4×2×1.0 mm² -P) (Class 5 bare copper + Black/Brown PVC + individual tinned Cu braid (H, ≥70%)); (02) Protective Earth Core (+1×1.0 żo) (Class 5 bare copper (1.0 mm²) with green/yellow PVC insulation in outer layer); (03) Core Wrap & Inner PVC Sheath (Y) (Polyester tape + extruded black mining PVC inner bedding sheath); (04) Overall Braid Shield (kono) (Collective tinned copper wire braid shield (≥70% optical coverage)); (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 YHKGSLYkonoynzo-P?

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