Cable jetting is a technique of placing cables in preinstalled ducts. It consist in a pushing force and a drag force that are simultaneously exerted on the cable by means of a mechanical pusher and a compressor providing a high speed air flow respectively.

Cable jetting enables you to:

• Install safely, depending on cable and duct design, very long sections of non-armoured cable up to 3km or more
• Place cables, in urban conditions, in one step, over several manholes, into their final location
• Create slack required for splicing, without exerting stress, at any point of the duct path
• Install over very long distances, i.e. 12 km or more, continuous lengths of cable in cascading mode
• Secure an almost constant daily installation capacity whatever the complexity of the duct run
• Remove old and place new cables in one step for network upgrading purposes
• Install a second or even third cable in an already occupied duct
• Install two cables in one duct simultaneously (requires two machines)

• Better cable protection during installation as stresses on the cable are much lower during installation
• Non armoured cables can be safely installed
• Much longer cables can be placed over tortuous routes as bends along the duct path, or duct undulations, have a little effect on the “jetting” performance
• Process control easy to learn
• Safer process for operators, provided safety rules applicable to compressed air systems are respected
• Reduced infrastructure and manpower costs
• Faster installation, hence higher daily production
