Abstract

This paper describes a cold shrink tube which is easy to install correctly. Habituation and three hands are typically necessary for installing a pre-stretched tube. "Three hands" mean one hand to support the cable, one to hold the pre-stretched tube (PST), and one to pull the ribbon. In this new process, a strip is attached to the starting edge of the tube by PSA tape. It is therefore possible to hold the cable jacket position and fix the cold shrink tube at the same time. It is also possible to set the first installation point correctly when the tube is installed.

PST with easy positioning tab

This paper describes a cold shrink tube which is easy to install correctly. Habituation and three hands are typically necessary for installing a pre-stretched tube. "Three hands" mean one hand to support the cable, one to hold the pre-stretched tube (PST), and one to pull the ribbon. In this new process, a strip is attached to the starting edge of the tube by PSA tape. It is therefore possible to hold the cable jacket position and fix the cold shrink tube at the same time. It is also possible to set the first installation point correctly when the tube is installed.

Background

The power cable accessories with the cold shrink tube is pretty good workability product and decrease installation times, but skill is needed to set the first installation point. For beginner workers, it is difficult to adjust tube position to the correct certain point. If beginners use cold shrink tube, it is necessary to use three hands. This invention can fix cold shrink tube position easily and reduce workload.

Description

Fig 2 shows the PST sample, and Figures 3 to 7 show the new PST installation method using the positioning tab.
