FAQs
Frequently Asked Questions
What is the Heat Shrink Transition Joint GTJ/1112 kV used for?
It is used for:
- Transition jointing of PILC cable to XLPE cable up to 12 kV
How do I choose the right size?
Choose by conductor size: the selection chart gives the kit for each cable size in sq mm. For example, a 3x240-300 sq mm cable takes kit GTJ-14.
How is it installed?
Clean and degrease the surface, position the part, then shrink it with a gas torch or a hot-air gun: keep the heat moving round it with a smooth, brushing motion so it recovers evenly without scorching. The instruction sheet in each kit gives the full sequence step by step, including where to start shrinking.
Where can I download the datasheet?
From the "Download datasheet" button at the top of this page, or here:
Can I get a quote, a sample or a size that is not listed?
