Ring terminals are very common, they are used by electricians in many types of work. They are designed primarily for terminating copper wires. Their main advantage is to increase the security and stability of the connection during operation, affecting at the reduction of heating wires and wire insulation.
By limiting overheating, they determine at the same time increasing of the vitality and durability of connections. For this reason, their became very common in use. For fixed connection of ring terminals it is necessary to use special crimping tools, depending on the cross section. Erko company offers several types of cable lugs. KOA cable terminals are made of tinned copper and have no galvanic isolation. Technical parameters of these cable terminals are maded according DIN 46234. They are used with cross sections from 0.1 mm2do 120mm2.
Another type of ring terminals are KOE cable lugs according to DIN 46234 with polyamide insulation, outstanding thermal resistance: from -40 ° to 125 ° C. Another type of ring terminals with insulation are KOV according to DIN 46237, for crimping the copper wires in a cross section of 0.5 mm2 to 6 mm2. In standard version of these cable terminals the edgesof folded tubular part are soldered.
