What governing standard and construction define PSKD (PSKD EMAG Double-Aramid Double-PUR Reeling Optical Cable)?

PSKD (PSKD EMAG Double-Aramid Double-PUR Reeling Optical Cable) is manufactured in accordance with ZN-TF-017 / EMAG / EN 60794-1-2 for Optical duty over -40 to +80 °C. Its 5-layer construction comprises Central Elastomeric Buffer Rod, 0.9 mm Tight-Buffered Fibres (8J) and HFFR-PUR Outer Jacket.

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

The minimum bending radius for PSKD is 10 × OD across its continuous operating temperature range of -40 to +80 °C, ensuring mechanical and dielectric reliability in mining and heavy industrial service.

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

From inside to outside, the construction sequence is: (01) Central Elastomeric Buffer Rod (Flexible central element stabilizing core geometry under small-radius reeling); (02) 0.9 mm Tight-Buffered Fibres (8J) (Color-coded 900 µm tight polyamide/elastomer buffered SM/MM fibres); (03) Inner Aramid & Inner PUR Sheath (First aramid yarn layer + extruded inner polyurethane cushioning sheath); (04) Outer Aramid Tensile Layer (2500 N) (Second concentric high-tenacity aramid layer for dynamic reeling load); (05) HFFR-PUR Outer Jacket (Black halogen-free flame-retardant polyurethane jacket (1.4 mm wall)).

What factory test certificates are supplied with PSKD?

Every production drum of PSKD undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per ZN-TF-017 / EMAG / EN 60794-1-2, and is delivered with an EN 10204 3.1 factory test certificate.
