How to choose the size of the cross section of the cable channel?Cable channels are used for external installation. wiresTheir mechanical protection also increases the safety of wiring from fires. Decorative channels consist of a hollow box and a cover. Currently, cable channels are made of metal (aluminum, galvanized steel) and plastic (usually polyvinyl chloride). PVC products are more common due to low prices and fairly high reliability.

Disadvantages of using boxesAdvantages of cable channels:

  • high aesthetics, which is very important for living rooms. Now make various cable channelsso you can choose the right decor for any interior. For example, products are made with imitation of wood texture and in different colors;
  • installation does not require special skills;
  • wiring mobility - wiring can be changed quickly and easily if necessary;
  • In addition to the ease of installation on the channels, you can place sockets and switches.

Now produce various products for laying cables:

  • minichannels (used for laying computer and telephone wires);
  • floor (have an oval box);
  • trunk;
  • baseboards;
  • halogen-free - the material of the box does not contain halogens: bromine, fluorine, iodine, chlorine, astatine. Such a product is environmentally friendly. It is especially important to use them in closed spaces;
  • parapet;
  • perforated - this device is used to reduce the cost of the product, reduce its weight and ease of installation;
  • flexible (great for mounting on uneven planes);
  • corner;
  • transparent;
  • boxes for air conditioners.

They sell PVC products in standard cuts, each two meters long. But the dimensions of the section can be different: from 12 to 12 to 100 to 60 and various intermediate dimensions (80 to 40, 50 to 16, 70 to 20, 40 to 40, and others). The shape is also determined by the type of product, for example, the corner channels have a triangular cross-section. Size is selected depending on the thickness of the wires.

Selection and purchase of cable channels

Sizes of decorative cable channelsTo choose the right plastic product you need to decide what size the box should be. Need to, to keep all wires free In his capacity and remained a small stock, which then can be useful. It is worth considering that the main channel, which stretches along the ceiling at the top, is better to choose a larger size, and the box for vertical taps to switches and sockets - a smaller one.

Next, you need to calculate how many channels you need to install. It is better to count the length with a margin of 15–20 percent. Because during work any part of the box can be spoiledAnd to buy the same cable the channel can not go out.

The cable channel can be selected in different colors, but you need to remember that white products are sold in a wider range.

Most manufacturers of plastic boxes, produce a variety of accessories for them, such as:

  • joints;
  • caps;
  • tees;
  • corner transitions;
  • external and internal angles.

On this better not to save and choose channels to which similar fittings are proposed, since it improves the appearance and greatly simplifies installation.

Preparation and installation of PVC boxes

Installation of PVC boxesPreparation begins from the ceiling and walls premises. If they are uneven and the geometry of the rooms is wrong, then you should not count on a high-quality installation of PVC boxes. There will be gaps between the wall and the box, the boxes will twist and it will not be possible to visually align them. Therefore, you first need to align the ceilings and walls.

Installation of PVC boxes can be performed both before the final finishing of the room, and after it. However, in the latter case need to work with the utmost care, as small flaws can not hide.

Cable channels can be marked with a simple pencil, but the tool and material for fasteners depends on the type of room walls. On painted and wooden walls, as well as on gypsum fiber, gypsum board, glass-magnesium sheet and wallpaper, you can simply paste the box. This will require glue, for example, liquid nails. It is only necessary to take into account that before the glue dries, the wires should be laid and the covers should not be closed.

On a wooden wall, you can mount the product with ordinary screws. Then you need a screwdriver with a long bat and a very thin metal drill about three millimeters. Drill need to prepare holes in the bottom of the box, through which screws are screwed or screws into the wood.

If the walls are made of concrete or brick, the box is fixed with screws and dowels. It happens this way: they apply the drilled product to the wall, mark the holes with a pencil, punch them, insert dowels and fasten the box with a screwdriver or a screwdriver.

It is better to measure the necessary length of each segment of the channel cable by a tape measure, or by directly applying the box to the wall where there is a possibility.

When installing, the horizontal position of the box can be checked at the building level, the vertical position - by a plumb line.

The covers of the installed channels are cut separately and first they are carefully folded into a separate place.

Carefully need to perform joints when moving from vertical to horizontal. The main thing is that after closing the channel with the lid there are no gaps visible to the eye, therefore the fittings are very useful here.

For the corner transition, the vertical and horizontal channels must be of the same size. For mounting "T-shaped" connections the same size of the boxes is no longer significant - in the wall of the main channel of a large size, a hole can be made for the outgoing cable.

Laying the wires in the box and closing the covers

Advantages of using boxesLay the wires in the channel is sometimes not so easy. Then the boxes with partitions inside are convenient, which help the cable not to fall out while the lid is open.

It is necessary to follow the sequence when laying the cables in the box. First, lay the entire cable and then close the cover. If the PVC box box lock is of high quality, it will hold the wires and will not open under their weight. It is necessary to ensure that the joints of the boxes do not coincide with the joints of the lids, then the whole cable channel line will look like a single unit and the joints will not be visible.

Completing the installation of cable channels

Why use cable channels?The wiring in the boxes fully meets the requirement of a change, therefore, to sew or seal the channel cover after installation is not entirely correct. However It is better to miss the sealant unsuccessful joints and misses. Disconnect switchboards, boxes and connect switches, sockets and fixtures for wiring in boxes.

Installing wiring in PVC boxes is a complex and time-consuming process. However, with a neat and competent approach the result will surpass all expectations both from a technical and aesthetic side.
