Supply of Thermistor Cables for NERC by Cortland Fibron BX Limited

About

UK Shared Business Services Limited awarded a contract to Cortland Fibron BX Limited for the supply of two thermistor cables, one 1400 m and one 1500 m in length, for the National Environment Research Council (NERC).

The cables are required to meet detailed technical specifications, including a minimum of 26 multi-stranded copper conductors with a cross-sectional area of at least 0.14 mm², a voltage rating of at least 24 V, a current rating of at least 100 mA, an aramid central strain member, and a polyurethane outer jacket with a minimum thickness of 1.4 mm.

The cables must support all but 100 m of their own length in water, 100 m in air, and a 100-kg ballast weight, with less than 1% stretch when deployed.

They must withstand hydrostatic pressures of 130 bar and 140 bar at their deepest points, respectively.

The cables will be supplied on drums with the deep end on the outside, and free-issued thermistors will be wired into the cables and sealed with polyurethane potting compound to form smooth terminations.

The contract value was £28,510.
