SWA Jointing

[londonlec]

Hi All,

I have an SWA resin joint to do, although the two cables are different sizes (35 and 50mm), the cables are existing and buried under tarmac.

Is there a torpedo kit which will let me terminate two different size cores?

I know the DNO near me tighten a bolt down onto the core using a socket, something like that would be ideal.

Many thanks.

That's what the kit is, giant brass terminal blocks, sometimes with snap off heads depending on the quality

I used to wrap copper core round the smaller core to make up size, but this was for indoors and inside a panel box. Better than a bolt.

Thanks guys, for some reason I thought they used standard through crimps.

don,t get a cheap thro. joint go for prysmain (pirelli) or 3M and get mechanical connectors (shear bolts)

Try a gel filled box it's great stuff

Will the 35mm be feeding the 50mm or the other way round

Does it matter? The protection should be for the smaller cable.

Done that many times with UG through joints. We had miles of 19/.044 (22mm) 11KV cabe, the smallest cable we kept on stock was 95mm.

just thought it would matter if the person dealing with the protection wasn,t aware of the 50/35 joint
