I'm a military aircraft Avionics engineer and we use solder sleeves on eurofighter typhoon for a number of purposes, one end is generally larger then the other to accommodate 2 cores, we use them in order to add extra bonding wires etc but also for repair of insulation. The solder in the centre can be mis shapen with pliers until it drops out. The clear heat shrink can then be slid over and used like regular shrink. The coloured glue will hermetically seal the repair with the coloured glue being a visual indicator that it is sealed fully

no way planes are held up with heat shrink connectors

Worth noting that you can get mastic lined heatshrink tubing, an alternative to adhesive lined that is better for sealing if the application needs to remain flexible, or in areas of vibration etc. Good for people to read up on the relevant COSHH datasheet for the relevant product too. E.g., the fumes aren't good and you don't want to be handling food afterwards etc.

We’ll check it out thanks 👍

Solder sleeves with or without the heat shrink element were used extensively in military aircraft radio systems to improve shielding along the cable run. The outer sheath was striped to reveal the shielding and a solder sleeve used to join another cable to connect to a grounding point.

Great insight 👍

Some years ago a Swedish spark was exposed to 400V while working on a live 3-phase supply cabinet. It turned out that when doing a termination another spark had used some heat shrink that he had lying about in his van. This heat shrink was unfortunately a semi conductive type that’s used while splicing cables >1000V but looks exactly like any other heat shrink. The outcome within that company was that all semi conductive heat shrinking that wasn’t used should be destroyed immediately at the work site.

[@awesomeelectricalengineer3487]

That's really scary, but useful information. Cheers

[@efixx]

Wow 😮

[@posei3960]

I have some 2" raychem heat shrink , it's has CONDUCTIVE stamped on it😱

[@trespire]

Semiconductive heat shrink ! That is counter intuative. I'll haveto start measuring for live voltage on tubing.

[@mfx1]

6:1 exists, high ratio clear sleeve is useful for shrinking over labels on some ready made cables.

[@Dog-whisperer7494]

I think heat shrink is a great product, so many different uses for it. And I can save you from a lot of problems. Fantastic video Gaz and Gordon as always 👍

[@efixx]

Thanks Sean

[@petetaylor9511]

Those SWA end sleeves are a great solution, very neat ( I've seen kopex used etc to give basic protection to the cores of swa but it looks rough ) - that's a much more professional outcome

[@pixels2polygonss]

I highly recommend when using the pre-solder shrink tubes to use a bit of electrical flux to help sink in that solder

[@harhar4607]

Clear, concise & truly educational-Bravo!

[@Mark-xr4zt]

Interesting and informative video 👍🏻 I think with the sleeving of bonding cables whilst it looks pretty, I think a lot of people have the words “no excess copper showing” running around their heads. Rather than thinking about strain relief. I think there is some debate to be had around the excess cooper issue, as in what constitutes too much. Especially when you consider manufactures RCD CU links where there is a lot of the conductive part of the neutral exposed but if you were to do your AM2 or an EICR you would be marked down for the same amount being exposed on your conductors. And it is these types of ambiguity that cause issues in our industry.

Idea of a mate: Heatshrink Tubes with Glue, ParaCord. For outdoor use - no knot anymore... :)

[@GSHElectrical]

I enjoy that 🦾

[@fritzmiller9792]

Voltage rating is most important but not mentioned. Second would be insulation integrity and how many layers of shrink to match the insulation rating.

[@ICYG69]

As someone who heat shrinks tooling this is funny😂

[@gabest4]

Are plastic soda bottles a good choice?

[@anton4video]

Can recommend hot melt tape for heat shrinkable tubing.

[@efixx]

Good thinking - we’ll get some in to try 👍

[@darylsavage119]

The heat shrink with crimps, seeing as they're from online retailers, I'm assuming they have no BS number, should they be used in a system then? Does the heat shrink (the fancy 3m one) offer an actual approved method of insulation for say, the numerous SWA supplies were seeing in meterboxes as you mention? Is this something that clarity could be sought on?

[@efixx]

3M heat shrinks gave pretty concise data sheets. The rest always need “careful” assessment

[@popandu1170]

thanks for the video chaps. I have a question: would a 2.5mm T&E cable entering the kitchen from the wall to be extended with heat shrink crimps be in accordance with the building regulations? The idea would be to extend the end point of the cable as currently in the way of the back of a dishwasher.

[@anton4video]

Suggestion for other video that is related, cold shrink tubing. Have used at work as no heat gun needed.

[@awesomeelectricalengineer3487]

How did you find it? I used cold shrink once and struggled to remove the plastic inner spiral.

[@anton4video]

@@awesomeelectricalengineer3487 Found cold shrink tubing because it can handle high temperature. 3M Cold Shrink Silicone Isolators 8440.

[@efixx]

A great follow up - we’ve got some at the unit

[@mattseabrook4536]

Great video... thanks

[@ricocasilli3307]

It had me for awhile, however when they stated that 1.0mm cable was being discontinued I was genuinely devastated …. Then I realised the date 🤦🏻

[@AsadMulla]

Good video

[@Conservator.]

9:11 Hi, How should you use these soldering joints when your cables has a solid kernel? (I’m Dutch and I’m not sure I’ve used the correct terms but I hope you’ll understand what I mean) Thanks in advance!

[@toodleoo88]

Firstly - thank you so much for your ongoing very helpful tutorials ! I have a pair of Sennheiser headphones.The headphones still work o.k.- but the rubber sorround (that protects the wires inside) - has frayed & deteriorated in sections - exposing bare wires. I have wrapped insulation tapes around the frayed sections - but it doesn't seem to be adhering too effectively. To save me cutting the headphone wires & having to resolder them - is it possible to cut the heat shrink tubing length ways, apply it to the wires & then heat it ? Do you think the shrink tubing will effectively adhere & grip by using this method ? If not, I would appreciate your advice of an alternative application please? Best regards with thanks for any assistance.

[@tookitogo]

You can (and should) just get an entire replacement cable. Almost all heat shrink is too rigid once shrunk to be comfortable for headphones - and each piece is a thing the cable likes to snag on. A whole new cable is less work and far more pleasant to use.

[@mfx1]

DeWalt cordless hot air gun with a decent sized battery lasts well.

[@UkJets892]

I work on the rails, and heat guns kill batteries, so out on track miles from anywhere, heat gums are useless. I use a plumbers blow torch, and it's much easier and quicker

[@mikew4625]

Rtf? Using TN-c cable for TNs s????

[@Roommate625]

Is this an approved wiring method per the manufacturer? I'm guessing not and they need to be in an accessible enclosure if installed. Someone's going watch this video and make this repair after hanging a picture (nail cuts cable) in a house not knowing it's illegal.

[@davidfalconer8913]

An old , but working 2 Kw oven element connected to a suitable ( safe ! ) flex , but , using ADHESIVE lined heatshrink ( lots of ! ) over the joints makes a 1st class emergency BATH WATER HEATER ... for when your boiler breaks down ( and , yes they do ! ) .. OMG you might say , but it works ( and is safe ! ) .... ( tried - n - tested ) ....... DAVE™🛑

[@mohdyasser973]

where can i buy this ?😊

[@shinodasanomedeto]

ケーブルの皮をむく道具は何ですか？日本には無い！とても欲しい

[@Justoutstanding]

I bet there flipping Yorkshire men

[@res1492]

Whats wrong with a liberal amount of lecky tape and a lighter?🤣

[@tookitogo]

Heat shrink is both more reliable and easier to use - and it looks neater to boot.
