Cable connector causes fever

Some electrical installation personnel when laying cables, often do not pay attention to the installation Quality: without casing at the insulating sleeve should be used; use the places do not fit the junction box junction box even not at the wire connector hinge method, instead of using illegal hook-shaped connection method. This kind of hooked connecting method of contact resistance is large, continuous heating at power up, gradually drying, charring the wood of nearby, and finally burning and cause a fire.
Heating not only resulted in a great loss of power wire connector, and can seriously affect the normal operation of the electrical equipment, ranging from circuit current increases, the life of electrical equipment, is suddenly interrupted by the ongoing production, scientific research, medical procedures and other activities, will cause fire and electric shock, caused immeasurable losses.
