Overheating of Electrical Joints

Problem Area Identified : Overheating of joints in electrical systems.

Reasons Identified : Contact not 100% which increases resistance. Loosing of joint over a period of time. Uneven pressure both in crimping as well as thimble.

Pressure is more near bolt and less as we approach edges.

Oxidation in copper and aluminum further increases resistance.
