Some electrical installation workers often neglect installation when laying wires
Quality: should not in the insulation casing casing; should be used where there is no wiring box installed boxes; even in wire joints instead of using splicing method, instead of using illegal hook shaped connecting method. The hook shaped connection method of contact resistance is large, energized continuously heat, will make the wood near gradually drying, carbonization, the final combustion occurs, causing a fire.
The wire hair will not only cause a lot of thermal power losses, and seriously affect the normal operation of electrical equipment, light line current increases, shortening the life span of electrical equipment, and will suddenly interrupt the ongoing production, scientific research, medical and other activities, will lead to a fire and electric shock accidents etc. that caused incalculable loss.
