Metal hose in PVC insulation: features, advantages and characteristics

Every year there are technological changes in various fields of activity. New developments are being introduced, more sophisticated and functional. Similar innovations, touched and systems for cable laying.

Metal hose in PVC insulation: characteristics and features

Metal hammers are used for laying cables of various networks:

• Communication lines;
• Electrical wiring systems;
• Ventilation and heating;
• Air conditioning systems, etc.

The direct purpose of the metal gun in PVC insulation is to prevent damage to the cable and to provide reliable fire safety in the event of a short circuit. If you compare it with a simple metal hose, the advantages will be on the side of the isolated one.

• It has a high water and dust permeability.
• Has increased resistance to the influence of external environmental factors.
• High strength of the materials of the product, not allowing breaks.
• Using metal hose in insulation, you can make the installation of cable wiring sealed.
• The product has a long service life, since the material has good resistance to corrosion.

The installation of the product can be carried out at temperatures ranging from -5 to +60 ° C, while the metal hose itself can withstand lower temperatures down to -45 ° C. It is also worth noting that the product has a high degree of protection against dust and moisture - IP65.

Metal hose in PVC insulation can be of different diameters, the smallest - 10 mm, the largest - 80 mm. It is made of steel, galvanized tape and insulating sheath. The material used for insulation - PVC (polyvinyl chloride) - has a high fire resistance and does not support combustion. These features make it possible to use the product for the installation of electrical networks in rooms at various enterprises where increased fire safety is required.

Alternative systems for cable wiring

There is a large number of products that make the installation of the cable quick and convenient. To do this, use:

• Plastic corrugation;
• Simple and perforated cable channels;
• Metal hose is usual and in isolation;
• Metal trays for the installation of electrical wiring.

To understand which product is most suitable for the installation of a particular wiring system, it is necessary to consider the merits and demerits of each.

Gofra

The merits include the flexibility and ease of the material. Corrugation can be used for both concealed and external wiring. Disadvantage: the fragility of the product, under mechanical influence, can break or crack.

Cable Channels

The product is intended only for installation of external wiring. A big plus is that the cable channel has a removable cover, which allows, if necessary, access to the wire. Also, manufacturers took care of the aesthetic appearance of the product, so in addition to white color cable channels are made for the color of wood. Minus - the material is inflexible, which causes some inconvenience in the installation.

Metal Trays

Well proven in the industrial field, as they prevent damage to the cable when subjected to mechanical stress. The drawback is that the material is not flexible and rather bulky.

Metal hose

The main advantage of the metal hose is its strength and flexibility. It is convenient for installation and can reliably protect the cable from damage. But, despite this, it still has its drawback. The tape from which it is made can, if misused, cause breaks.

Advantages of metal hose with PVC sheath

Metal hose in PVC is a corrugated metal pipe in insulation, which allows it to be used for the wiring system even inside structures that can easily ignite. When folded, it does not lead to a change in the flow section inside and excludes the appearance of microcracks and disturbances in the metal under mechanical action.

Manufacturers produce metal hose in PVC insulation with bays: small diameter of 50 m, large - 30 m. The installation does not require the use of special, special tools. All that is needed is a bulgarian or a pipe cutter. Fittings made of brass are used to connect the metal hose.

Metal hose in PVC insulation is very reliable in operation. Since the material from which it is made is sufficiently durable, the metal hose does not require additional maintenance during use. It can be used in concrete screeds, lay in stitches, covered with decorative panels or plastered into the wall.

In modern construction quite often began to use metal hose. The price of a metal hose will depend on the diameter of the product. Naturally, the larger the diameter, the higher the cost. On average, a metal hose with a diameter of 10 mm will cost 10 rubles per 1 meter, and a diameter of 80 mm - 250 rubles per 1 meter.

The use of such material for the installation of electrical wiring will protect the dwelling from possible fires in the event of a short circuit.
