ETA have developed a range of jetting sleds for the burial of cables for the power market. ETA’s extensive research and trials have led to a design that optimises jetting efficiency. Below you will find details of ETA’s power cable laying jetting sleds.

 

 

 

To discuss the suitability of an ETA jet sled for your project or ETA’s capabilities to repair and modify existing equipment please call:
