Duct Checking Equipment

Direct buried ducts can suffer from compaction, reduction or other obstructions, therefore, before cable installation begins, CBS recommends that each length of duct is checked for continuity and freedom from obstruction. Various items of hardware are available for checking the ducts.

Pressurisation Kit

The CBS Duct Pressurisation Kit has been designed to test the integrity of the duct by checking that the duct has no leaks. This will confirm that the duct holds air pressure, prior to cable blowing.

Cable Overblowing Junction Box

The CBS Cable Overblowing Junction Box has been designed to install a new cable or duct-tubes into an existing occupied sub-duct (subject to space being available).

Cable Guiding Heads

These are screwed on to the end of the cable to reduce friction during cable blowing.

Duct Cutter & Slitter

Quick and easy to use the adjustable die cast circumferential cutter or slitter which provides a clean cut of plastic ducts

Lubricant

Water based blowing lubricant

Tube Blowing Accessories

CBS has developed a micro tube pressuring system, which prevent potential problems where the blowing air can collapse the tubes. The system charges the tubes on their drums, this keeps the micro tubes stiff and resilient during the tube installation procedure.
