HV Cable Termination-Heat shrink vs cold shrink
HV Cable Termination-Heat shrink vs cold shrink
(OP)
Hi
Can anybody point out any article on this subject. I have come to learn that Heat shrink cable termination is no longer recommended in Medium voltage switchgear(1000V to 52kV).Instead cold-shrink termination is recommended.
The reason being when heat shrink termination is applied, over the years it becomes sensitive to moisture and emits a chemical reaction which is harmful for the switchgear.
Thanks for your inputs.

Both HS and CS terminations perform very well... if they are installed properly!! Both are highly qualified for many installation scenarios. HS terminations have a longer history of use and are generally seen to more mechanically durable. CS terminations are easier to apply. HS require more skill to install -heat the material enough... but not too much - that's a tough one from some technicians. I hope this helps.

HS has its long standing history of good use in the industry. The advantage of CS is that on HV motors (ie. 6.6kV) which requires testing every year or periodically, CS has its economical advantage 'cos it can be reused.

Nevertheless, CS boast of unrivaled ease in installation and excellent reliability comparable to HS...but as pointed out by benlanz, proper installation (including preparation) plays a similar important role in the overall performance of termination and splices.

One more reason to sometimes consider a cold shrink in typical industrial applications: when multiple cables are landed in parallel on a compact pad, it is difficult to uniformly apply the heat all the way around each to make a satisfactory Heat Shrink terminations.
