Round pre-insulated terminal is just a series of many specifications in the cold press terminal, this series of models have a lot of wiring range is also very wide, the current market demand is very high, especially in the terminal line processing often use this connector.

Round pre-insulated terminals are generally made of purple copper material, insulation sheath using PVC or nylon material, there is a good conductivity at the same time, there is a good insulation effect, the use of long time is not easy to aging. This series of cold pressed terminals are characterized by good quality, not easy to loosen after pressing, and can be used normally at a temperature of 10-105 degrees.

After understanding the characteristics of the round pre-insulated terminals, in order to help you choose the right model faster, some selection points clear will be half the effort. Round pre-insulated terminal wiring range in 1.25-22 square, different wiring square number corresponding to the wire cross-section also has a difference, this can be determined according to the need to connect the wire and cable.

In addition to the wire cross-section of this data, round pre-insulated terminal models and screw hole diameter of this parameter composition, the hole is simply the size of the fixing screw, if you choose too small or too large, there will be connected or off the problem, so this parameter selection should also be determined clearly.

So that everyone in the selection of round pre-insulated terminals, wire cross-section and screw hole diameter must be determined clearly, so that in the selection of faster. If you are not clear about these two parameters, you can provide the corresponding wire cross-section and screw size to choose.
