What governing standard and construction define DSM 40-01 (DSM 40-01 Subsea Acoustic Coaxial Cable)?

DSM 40-01 (DSM 40-01 Subsea Acoustic Coaxial Cable) is engineered in accordance with IEC 60092-350 / ISO 13628-5 / MIL-C-17 for 4.5 kV RMS service over -40 °C to +80 °C. Its 5-layer construction comprises stranded tinned copper center conductor, fep fluoropolymer dielectric core and neoprene (polychloroprene) outer sheath.

What is the minimum bending radius and operating temperature range for DSM 40-01?

The minimum bending radius for DSM 40-01 is 10–15 × OD across its continuous operating temperature range of -40 °C to +80 °C, ensuring mechanical, optical and dielectric stability during subsea deployment and winch handling.

How are the concentric layers of DSM 40-01 arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded Tinned Copper Center Conductor (Electrolytic tinned copper strands (7 x 0.40 mm / 0.88 mm²) for low-loss RF & sonar transmission); (02) FEP Fluoropolymer Dielectric Core (Extruded fluorinated ethylene propylene (FEP) solid dielectric core (OD 5.0 mm, 4.5 kV peak)); (03) Tinned Copper Coaxial Braid Screen (High-coverage woven tinned copper wire coaxial return conductor and EMI screen (>= 90% optical coverage)); (04) Rubberized Separator Tape (Helically lapped rubberized fabric binding tape stabilizing the coaxial braid under hydrostatic pressure); (05) Neoprene (Polychloroprene) Outer Sheath (Heavy-duty black polychloroprene (CR / Neoprene) marine outer jacket resistant to seawater, oil, and abrasion).

What factory test certificates are supplied with DSM 40-01?

Every production drum or assembly of DSM 40-01 undergoes routine electrical/optical continuity, high-voltage dielectric and dimensional testing per IEC 60092-350 / ISO 13628-5 / MIL-C-17, and is delivered with an EN 10204 3.1 factory test certificate.
