在各种建筑物装修之前，敷设电线无疑是装修的第一道工序。而为了美观，这些电线全部都埋在隔墙内和地板下，属于隐蔽工程。一旦装修完毕，这些电线再想改动更换己是不可能的了。因此，无论是家庭还是办公室等单位装修，对电线的穿管保护尤为重要。目前，塑料电线管比较时髦，但品种良莠不齐，好坏难辨。如果对此你并不十分了解，那不妨听听专家的意见。 Before the renovation of various buildings, the laying of wires is undoubtedly the first process of decoration. In order to be beautiful, these wires are all buried inside the partition wall and under the floor, which is a hidden project. Once the renovations are completed, it is impossible for these wires to change and change. Therefore, regardless of the decoration of a home or an office, it is particularly important to protect the electrical wires. At present, plastic wire and cable are more fashionable, but the varieties are mixed, and they are difficult to distinguish. If you don’t know much about this, you may wish to listen to the opinions of experts.
