What applications is L-2YYQY engineered for?

L-2YYQY 300/500 V steel-braid-armoured Ex-i mining hybrid cable combining 2 × 6 mm² PE power cores, 2 × (2 × 0.5 mm²) screened control pairs and a 1 × 0.5 mm² pilot core under galvanized steel wire braid armour and a blue PVC Ex-i sheath. It is built to IEC 60079-14 / PN-G-91006 for underground coal & methane-hazard mine automation and longwall roof support electro-hydraulic control.

What are the minimum bending radius and operating temperature range for L-2YYQY?

The minimum bending radius for L-2YYQY is 10 × OD across its continuous operating temperature range of -30 °C to +70 °C, ensuring mechanical and dielectric stability in industrial service.

How are the concentric layers of L-2YYQY arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Power Cores (2x6 mm²) (Two 6.0 mm² Class 5 flexible plain annealed copper power cores with low-capacitance polyethylene (PE) insulation (Blue and Black)); (02) Screened Control Pairs (2x2x0.5 mm²) (Two twisted 0.5 mm² PE-insulated control pairs (Blue/Grey & Blue/White), each wrapped with PET tape and an individual tinned copper braid); (03) Unscreened Control Core (1x0.5 mm²) (One 0.5 mm² Class 5 flexible plain copper auxiliary control conductor with brown polyethylene (PE) insulation); (04) Inner Sheath & Steel Braid Armour (Extruded grey PVC inner bedding sheath protected by a galvanized steel wire braid armour (Q) against rockfall and crush hazards); (05) Intrinsically Safe Outer Sheath (Blue flame-retardant polyvinyl chloride (PVC) outer sheath identifying intrinsically safe (Ex-i) underground mining circuits).

What factory test certificates are supplied with L-2YYQY?

Every production drum of L-2YYQY undergoes routine electrical continuity, high-voltage dielectric and dimensional testing per IEC 60079-14 / PN-G-91006, and is delivered with an EN 10204 3.1 factory test certificate.
