Insulated terminals
Cable terminals are used to connect the cable with other elements of the installation. Choosing the right products affects the durability and security of the network. They are selected depending on the current load, the size of the screw hole, the cross-section of the cable, and whether the installation was made in accordance with the DIN standard (defined by the German Institute for Standardization). Cable terminals in the EL12 offer differ in the type of material from which they were made. They can be, for example, copper or aluminum. In terms of construction and application, cable terminals can be divided into: ferrule terminals, ring terminals, tubular terminals, double wire terminals and connector sleeves. In order to select the appropriate terminal for the cable, it is worth getting acquainted with the markings of the construction of the working conductor of the cables. RE is a single-wire conductor, while multi-wire is marked with the symbol RM. The shape of the cable also matters. If we find the RMC or RMV symbol on it, it means that the conductor is round, multi-wire and dense. One can also distinguish single-wire sector conductor (SE) and multi-wire sector conductor (SM). Depending on the type of terminals, it is possible to mount them by screwing, soldering or pressing. In the case of the last option, check what is the appropriate form of crimping the terminal: hexagonal, oval, square, trapezoidal or single indentation. The latter method is used for plug-in terminals made according to DIN 46230, as well as copper tubular terminals in the wire cross-section range of 0.5 - 6 mm2. Trapezoidal and square crimping works well for copper ferrules. The hexagonal connection is suitable for both copper and aluminum terminals. Several different types of tools can be used for crimping: hand-held, pneumatic and battery-operated. The places where crimping should be done should be marked with lines on the tip.
