Cembre BKF-F 405 | Reinforced PA 6.6 Insulated Female Disconnect Terminals
Cembre bKf-f 405
Cembre ‘KF’ type terminals are designed to offer improved mechanical and electrical integrity under heavy-duty LV cable termination applications using female disconnect terminals. This is achieved via a copper sleeve located between the copper barrel and polyamide insulation of the cable terminal. Then during crimping cables the insulation of the conductor is integrated into the crimp due to the copper sleeve being deformed around it by the crimping tool to maintain the level of ‘grip’ required in applications subject to continuous mechanical vibrations.
BKF-F 405 type terminals are manufactured by Cembre from electrolytic copper Cu-ETP CWOO4A according to UNI EN 13599 and are tin plated to a minimum thickness of 3µm.
