Electrical connectors differ from shear off screw connectors in many aspects e.g. when it comes to the form and the method of installation. The process of mounting distinguishes them the most.
Crimping vs shear off screws
Electrical connectors in the crimping system are mounted with the help of crimping tools. After we choose the right cable terminal or cable connector that corresponds with the particular cross-section, material and the type of conductor, we have to choose the right crimping form. Then we have to remove the insulation from the wire on the length that corresponds to the tubular part of the connector or terminal. However, before doing that you have to clean the oxides and air raids from the wire. When this is done we have to insert the wire to the narrow part of the electrical connector. Then we choose one of the crimping tools recommended by the manufacturer and the right crimping dies. We crimp the connector until the dies come together or the overflow valve starts working. It is also important to use the direction of crimping specified by the manufacturer.
In case of shear off screw connectors each product is equipped with shear off screws. With the help of ratchet handle for tightening shear off screws and wrench socket you have to tight the screws until they break. One product can be used for both copper and aluminum wires with different type of conductors and wide range of cross-sections.
Versatility and the wide range of products
In case of shear off screw connector the fact that one product can be used for both copper and aluminum wires with different type of conductors and wide range of cross-sections is a huge advantage. An additional advantage is that the range of cross-sections is very wide e.g. shear off screw connector SKN 10-2595 for Cu and Al has the cross-section of 25 – 95 mm2. In case of traditional electrical connectors one should appreciate the wide range of products in many different sizes and crimping tools that perfectly match the connectors.
Speed and easiness of installation
In this aspect without any doubt the shear off screw connectors are better. All you have to do is to insert the wire into wire and with the help of ratchet handle and wrench socket tighten the screws until they break. One tool is enough and the connection is ready.
