KORW lugs tested with Class 2 and Class 5 Cu conductors with IEn certification for rated voltage up to 36kV class 2 and 5 conductors.
KORW-type ring lugs with a "narrowed" palm have been designed specifically for connection directly to the terminals of a switchgear.
Most of these types of connections are made of copper conductors of the 5th class of flexibility, i.e. H07VK. Crimping tubular part of a cable lug KORW type should be crimped with special dies (shape "hexagonal with notches" ) KP22-FL... type on a 5 class conductor.
To meet the needs of users, we have tested KORW-type lugs pressed on both class 2 and class 5 conductors for compliance with the requirements of the standard:
PN EN IEC 61238-1-3:2020-01 "Crimp and screw connectors for power cables - Part 1-3: Test methods and requirements for crimp and screw connectors for power cables rated above 1 kV (Um = 1.2 kV) to 36 kV (Um = 42 kV) tested on stripped conductors"
These lugs received positive test results confirming their mechanical strength in class 1 and electrical strength in class A - with short-circuit test.
The use of cables with the lugs tested in accordance with the above standard for connection to switchgear guarantees the reliability and efficiency of the power distribution system.
