What governing standard and construction define FEVE 1.8/3 kV (FEVE 1.8/3 kV Armoured Subsea Umbilical Cable)?

FEVE 1.8/3 kV (FEVE 1.8/3 kV Armoured Subsea Umbilical Cable) is engineered in accordance with IEC 60502-1 / ISO 13628-5 / DNV-ST-E402 for 1.8/3 (3.6) kV service over -40 °C to +90 °C. Its 6-layer construction comprises stranded copper power & pilot conductors, polyethylene (pe / xlpe) power & pilot insulation and high-density polyethylene (hdpe) subsea outer sheath.

What is the minimum bending radius and operating temperature range for FEVE 1.8/3 kV?

The minimum bending radius for FEVE 1.8/3 kV is 12–20 × OD across its continuous operating temperature range of -40 °C to +90 °C, ensuring mechanical, optical and dielectric stability during subsea deployment and winch handling.

How are the concentric layers of FEVE 1.8/3 kV arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded Copper Power & Pilot Conductors (Three compacted circular stranded copper phase conductors (3 x 70–240 mm²) plus two 1.5 mm² copper pilot/monitoring cores); (02) Polyethylene (PE / XLPE) Power & Pilot Insulation (Extruded heavy-wall polyethylene insulation on phase cores (Brown, Black, Grey, 1.8/3 (3.6) kV) and pilot cores); (03) Laser-Welded Stainless Steel Optical Tube (12F SM) (Hermetically sealed stainless steel tube containing 12 single-mode (ITU-T G.652.D) optical fibers in thixotropic gel with PE jacket); (04) Petrolatum-Filled Interstices & PE Inner Sheath (Water-blocking petrolatum compound filling core interstices beneath an extruded polyethylene (PE) inner bedding sheath); (05) Contra-Helical Double Galvanized Steel Wire Armour (DWA) (Two layers of heavy galvanized steel round wires applied in counter-helical lay for high tensile and seabed impact protection); (06) High-Density Polyethylene (HDPE) Subsea Outer Sheath (Abrasion- and UV-resistant black high-density polyethylene (HDPE) outer serving for seabed laying and shore landings).

What factory test certificates are supplied with FEVE 1.8/3 kV?

Every production drum or assembly of FEVE 1.8/3 kV undergoes routine electrical/optical continuity, high-voltage dielectric and dimensional testing per IEC 60502-1 / ISO 13628-5 / DNV-ST-E402, and is delivered with an EN 10204 3.1 factory test certificate.
