FAQs
Frequently Asked Questions
What is the Cold Shrink End Cap used for?
It is used for:
- Sealing cable ends against water and moisture ingress
- Compatible with XLPE, PVC, PILC and rubber-sheathed cable jackets
How do I choose the right size?
Measure the outside diameter of the cable and choose the code whose "Application Range" covers it. For example, GCCE - 03 fits a cable of 23–38 mm. Where two ranges overlap, either code fits.
How is it installed?
No heat and no tools. Place it over the cable, then pull and unwind the spiral support core: it shrinks onto the cable as the core comes out. Remove the core completely so it recovers fully.
Which standards and test methods are quoted for it?
These, with the values in the Technical Specification on this page:
- ASTM D-412
- ASTM D-624C
- ASTM G-21
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.
