FAQs
Frequently Asked Questions
What is the GTJ Series Heat Shrink Transition Joint Kit used for?
It is used for:
- PILC-to-XLPE cable transition joints
- Branch joints on MV distribution cable
- PILC cable accessories 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?
Send your cable details, quantity and application with the "Request a Quote or Sample" form at the foot of this page. For a size or variant that is not in the chart, describe what you need there, or use Technical support at the top of the page, and the technical team will confirm what can be supplied.
