12:2 Some important comments on contact crimping About System Elpress There is a wide range of electrical terminals today, and it can be difficult to know if you have chosen the right solution for your installation. A first step is to ensure that a system is chosen, consisting of terminal, tools and a standard conductor. In order for this combination of material to be classified as a system, there must be common test documentation, a type test according to a standard relevant to the material. There may also be a need to identify the correct terminal depending on the cable class. Cables are divided into different classes depending on their structure. With System Elpress you get a complete solution, KRF/KSF in combination with Dual can be combined with all Cu cable classes. Elpress systems for aluminium indented crimping are a robust solution that can be used with all types of Al cables. Not choosing a system carries great risks. All terminals are designed with respect to a specific tool system. Small differences in dimensions of terminals and tools can lead to serious consequences, such as hot running or fire. Terminals Elpress terminals have been developed over 60 years of continuous work to always meet the highest standards. Our terminals are designed to be able to operate at a continuous temperature of 90°C and to always be able to carry the same load that the relevant cable area can handle. This means, among other things, that tubes for our KRF/KSF are dimensioned to be adapted to the cable’s conductivity. This type of terminal should be crimped with a hexagonal geometry that provides a symmetrical shape that distributes crimp force evenly and ensures that thin strands are not damaged shortening the lifetime of the connection. Our aluminium terminals are designed according to the same criteria and requirements as mentioned above, and should be crimped with a punch tool that ensures that the aluminium insulating oxide layer is broken and that good points of contact are created between conductors and terminal. Cables Elpress terminal systems are designed to be used in conjunction with cables according to IEC 60228. This is an international standard used all over the world and describes the structure and conductivity of a cable (Ω/km) The norm divides cables into classes as shown below. Class 1 Class 2 Class 5 Class 6 Solid conductor Stranded conductor Flexible conductor High flexible conductor Types of conductor Cables in each class shall have mechanical and electrical properties that meet the requirements of the norm, which means that they can be used with System Elpress without special adaptation. In addition to the classification of conductors, the differences between cables are mainly in the design of the insulation. Hexagonal crimping. Indented crimping. Trained users Another important aspect of a system is a knowledgeable and trained operator. Good and safe work requires knowledge of materials, regulations and the importance of using a system solution. We offer company-adapted training that includes both theoretical and practical parts.
