In the layout of the electric wire for the house decoration, the wire should be insulated.
Wire to be insulated pipe
Buried lines can not be directly embedded in plastering layer, but in insulated pipes of electric wires. The wires in the casing can not have a twist or joint. Under normal circumstances, a group of wires are not allowed to exceed three turns when they are buried, and more than three turns must be connected. In order to fear the effect of beauty and to save things, a group of wires turn around the head in a group of wire laying, and the short time will not affect the use, but one of the wires will be out of question in the future, and a group of wires will not be used.
