Scope of the use of metal grinders.
During the laying of cable lines, the question often raises, and what exactly can be protected by electrical wiring, which can be subjected to mechanical damage. In this case, the best option will be the use of metal -burning, as this is the most convenient material for laying communications and electric networks, as well as for installing security and fire alarms.
Due to its excellent flexibility, the metal sleeve is great for laying lines on surfaces with all kinds of irregularities and twists. Previously, only an uninsulated sleeve, that is, not protected by the outer shell, was proposed on the market. A similar metal-burning in the weather became quite quickly unsuitable for further operation, due to the fact that the galvanized tape, which is the main one for any metal sleeve, was corroded. To extend the service life of this product, consumers had to subject it to special processing of IDE.
Now, the need for such procedures completely disappeared, because a metal hook with PVC isolation appeared on the market, which reliably protects a galvanized tape from corrosion. Thus, the leaky metal sleeve in its properties has become like a sealed.
The use of PVC insulation sharply expanded the scope. Now it can be used to transport bulk and powder substances, as well as to arrange ventilation systems. The aesthetic properties of this product have increased. In its appearance, it now resembles a corrugation made of plastic, but at the same time with greater strength.
