Immersion & wet locations
Water-blocked core matrix and hydrolysis-resistant subsea jacketing withstand continuous deepwater hydrostatic pressure.
Product
A301592 / A216375 / A310255 (UNOLS 0.322" / 0.375" / 0.252") Double-Armored CTD & Oceanographic Instrumentation Cable (UNOLS 0.322" CTD, 0.6/1 kV, -40 °C to +80 °C, min. bend radius 12 × OD).
Typical values for this cable type, based on UNOLS Standard 0.322" / 0.375" Double-Armored CTD Cable — confirmed in the datasheet and quotation for your order.
Application fit
A301592 / A216375 / A310255 (UNOLS 0.322" / 0.375" / 0.252") Double-Armored CTD & Oceanographic Instrumentation Cable (UNOLS 0.322" CTD, 0.6/1 kV, -40 °C to +80 °C, min. bend radius 12 × OD).
Water-blocked core matrix and hydrolysis-resistant subsea jacketing withstand continuous deepwater hydrostatic pressure.
Torque-balanced aramid or contra-helical steel armour supports vertical winch deployment without hockling.
Marine-grade outer sheath and armour package resist LARS sheave abrasion, UV exposure and salt-spray corrosion.
High tensile breaking strength supports underwater towing, ROV excursion and seabed plough/trencher duty.
Subsea umbilical and tow construction is not intended for high-cycle indoor factory drag chains.
