Today, samples of not only domestic production, but also imported ones have firmly strengthened in the field of sales of a construction tool. Unfortunately, in recent years, the dynamics of sales are such that imported goods have more and more replace domestic and occupy a large share of sales. By the way, it will not be superfluous to buy a laminate for the home in advance.
However, all construction equipment of imported production must have certificates confirming the possibility of using equipment in local networks. At the same time, an electrical tool with autonomous power is wiser to buy for use in places where constant power sources are not available.
However, such tool samples are not free from the shortcomings. A key drawback is a short period of work between the recall and a fairly high price of a spare set of battery power sources. The models of the tool that are powered by a variable voltage network should have high -quality current protection, since it can cause injuries. Typically, power supply tools from the network are equipped with double insulation. The first of the levels isolates the electric nodes of the inventory, and the second protects the body of the entire product. Products with such isolation on the product housing and in a technical passport have a special mark.
