Secure Rubber Boot on TR-343 Transducer Elements

A key component of sonar systems for surface military vessels is the AN/SQS-53C Sonar array, made up of 576 TR-343 Transducers, the array is located in the “bulb” on the bow just below the water surface. Each of those transducers contains a rubber boot or sleeve secured with an ULTRA-LOK Alloy 625 band.

BAND-IT IDENTIFIED AS ONLY SOURCE

During the sourcing process, the US Navy identified BAND-IT as the only responsible source capable of providing the required supplies. Citing the potential for delays and unrecovered costs, the agency chose BAND-IT as the only approved manufacturer based on performance and testing requirements of the Critical Item Production Fabrication Specifications (CIPFS) for the Transducer.

Stainless Steel Cable Ties

33kV/132kV Offshore Substations – LV, MV & HV power cables providing support to a wind farms distribution of electricity are located using stainless steel cable ties, banding and strapping. Image: Siemens. Durable, reliable and stable cable management products are specified for wind turbine applications where extreme mechanical stress, vibration, UV and seawater exposure preclude the use of sub-standard non-metallic types of cable ties.
