FAQs
Frequently Asked Questions
What is the MV Cable Joints used for?
It is used for:
- MV cable splicing for XLPE and PVC insulated cable
- Paper-insulated lead-covered MV cable splicing
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 4x70-150 sq mm cable takes GXLT-4 (1.1 kV) or GXLT-14 (3.3 kV).
Which standards and test methods are quoted for it?
These:
- IEC 60502
- IEC 60060
- IEC 60230
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.
