Electrical Wire Connectors Screw Terminals

Electrical wire connectors screw terminals, or ribbed wire caps, are special electrical supplies. They allow you to tightly connect two or more conductors only by hand, without using additional tools. 

When working with electrical circuits, it is sometimes necessary to twist the cables together. Electrical contact is formed directly at the connection point, which has a resistance. In the place of such contact, current leakage can occur, insulation is broken, and safety deteriorates. It is PPE caps that allow you to avoid all these phenomena. 

What are the electrical wire connectors screw terminals

These are connecting insulating clamps, in the form of a plastic case. Inside there is a threaded metal sleeve. They have a conical shape. Presented in Ukraine in various sizes. Designed for twisting conductors of various cross-sections. 

Produced in a variety of colors. A certain color corresponds to the diameter of the cable for which the product is intended. 

These attachments are reusable. They can be easily removed from the old attachment point and transferred to a new one. 

There is a classification of caps, which is the abbreviation CIW and numbers from 1 to 5 (for example, PPE-3). The figure is an indicator of the cross-section, and the number of wires to be connected. 

How to use a twist for wires 

Installation of caps is carried out on pre-prepared cables without special devices and high qualifications.

The direct installation process involves inserting conductors into the part itself and turning this part itself several times. If necessary, the resulting structure can be easily disassembled. When connected with a cap, the aluminum is tightly pressed by a conical spring and functions unhindered for a long time. 

Rules for working with a ribbed wire cap

The resulting connection is quite compact and ergonomic, and it is simple and convenient to use caps in Ukraine. However, you should know some rules for working with them. 

1. It is forbidden to twist aluminum wires with copper ones due to the development of electrochemical processes. This leads to dangerous destruction of the contact. 
2. The length of the twist point should be equal to or slightly less than the height of the cap. The more wires you connect, the longer this length should be. Therefore, it is necessary to choose the correct size of PPE depending on the number and diameter of wires. 
3. These products are only suitable for solid wires. 
4. The diameter of the conductors to be connected must be indicated in the accompanying documentation. 
5. Manufacturers from different countries may have different designations. Therefore, it is worth looking not at the marking, but the overall dimensions of the PPE.
