Cable Jointing Material Kit for Housing Complex“F-Touch Cover Mini”

1.

INTRODUCTION

Recently, as home electric appliances become morediversified accompanied by increasing demand, a rapid
growth is seen in electrical work to upgrade the powerreceiving capacity of housings. Many owners including
Urban Renaissance Agency are systematically implementing a plan of trunk cable upgrading (i.e., 40 A per household) to increase the power receiving capacity of housings. In the case of housing complexes, since branchcables are mainly used for power distribution from thecommon trunk cable to every household, a wide variety ofworking methods are employed to deal with the actualsite conditions. Moreover, unlike new installation works,
the capacity upgrading work faces demanding site conditions such as limited existing spaces as well as brief working hours to shorten interruption of electric service.
In order to respond to such market trends, we have beenworking on the application of our proprietary cable jointing
technologies to develop new cable jointing materials exclusively for housing complex, and have succeeded in launching the sale of various products including “F-Touch Cover”
for bundle jointing of triplex cables. We have recently
expanded the applicability of the existing products to add“F-Touch Cover Mini” shown in Figure 1 to our productlineup. The new product is the most compact sized branching joint in the industry with two branch arms on eitherside. This F-Touch Cover Mini allows for two-arm branching
work comfortably and assuredly inside a horizontal cableduct of approx. 80 mm x 70 mm in inner dimension.

F-TOUCH COVER MINI

2.1 Features
Whereas the conventional F-Touch Cover for bundle jointing of triplex cables provides two branches to the same
direction with respect to a vertical trunk cable as shown in
Figure 2, F-Touch Cover Mini developed here is a cable
jointing kit exclusively for two-arm, either-side branchingof a horizontal trunk cable in a cable duct. See Figure 3.

This jointing kit has been designed, limiting its intended
applications to indoor environments only and taking
advantage of thin-wall molding technology for its plastic
cover, to provide a combination of cable sizes necessary
for trunk cable repair work, thereby realizing the mostcompact cable joint in the industry.
2.2 Assembly Performance
The method for assembling this product is very straightforward and reliable. Just wrap the insulating putty sheet
prepared exclusively onto the jointed connector, andinstall the attached cover. The putty sheet can easily bewrapped by anyone, and needs no curing time to wait
unlike resin hardening-type jointing kit. Also, high reliability is assured since a robust cover is used to protect theputty-treated portion. See Figures 4 (a) through 4 (d). As
described, the assembly work is simple and least timeconsuming.

CONCLUSION

F-Touch Cover Mini has been developed targeted at repair
work of housing main cables after the model of Urban
Renaissance Agency and the like. But it is also applicableto other repair works such as those in housing complexes
owned by prefectural and municipal agencies or by companies, and thus it is expected to see market expansion inthe future. We intend to make efforts to develop Only-One
Products in response to customers’ needs, making contributions to society by offering good cable jointing materials.
