The Importance Of Wire Stripping To Copper Terminal Blocks

If the wire stripping is too short, the spring crimping area will be too small, which will cause signs of heating of copper terminal block. Insufficient wire stripping will reduce the actual contact area and increase the contact resistance. During long-term operation, copper distribution block will produce local overheating and oxidation on the contact surface. In severe cases, copper terminal strip will burn out or trip due to poor contact (industry fault analysis consistently points out this type of cause).
