Ordering example:
The cable is 36kV, 3*95mm² aluminum conductor with core insulation diameter of 29mm. Order W36CBK1DM13.
Note:
Sealing or solderless grounding kits shall be ordered separately.
Please add "-X" for cable with copper wire shield without armour, like W36CBK1D05C3-X.
Feel free to contact us for detailed information.
*Please make sure the lug code mates with the connector body size if you need to repack the connector kits.
