HellermannTyton’s SABS approved range of XLPE lugs and ferrules are designed for single and multi-core XLPE (cross-linked polyethylene insulation) cable applications. Suitable for usage in medium voltage distribution networks such as utilities, power distribution and mining.
In general, lugs and ferrules are fixed to the cables and wires by inserting the conductor/s into the ‘barrel’ (tube) of the device and then ‘crimping’ (squeezing) the barrel onto the conductor to form a secure mechanical and electrical joint.
In order to achieve this, the right lug or ferrule needs to be selected according to the cable used and the area of application.
Why use a HellermannTyton XLPE lug and ferrule with XLPE cable?
• The cable is compacted resulting in smaller core sizes than standard cable. XLPE lugs and ferrules internal diameters are smaller than standard lugs and ferrules to fit the core size and to prevent over-crimping.
• XLPE cables are used mainly in distribution networks to prevent moisture ingress.
• XLPE lugs have no inspection window aiding the sealing of the cable end.
• XLPE lugs have a thicker wall improving the crimp and therefore better heat dissipation (no hot joints).
• SABS approved (SANS IEC 61238-1:2003) lugs and ferrules.
Standard lugs and ferrules need to be over-crimped when used on XLPE cables, which can cause hot spots and the lug to fail or burn-off. Over crimping also damages a lug and therefore limits the lifetime, and standard lugs and ferrules have an inspection window that allows water ingress.
