Types and installation points of decorative wire sleeve

In our life, every family needs electricity. Wires will be installed where there is electricity, but for the sake of safety, wire sleeves are usually used, but there are many kinds of wire sleeves, so we need to pay special attention when installing them. Then let's take a look at the types of decorative wire sleeves and the installation points of wire sleeves with Bian Xiao.

Composite steel wire sheathed tube

The conductor of the composite conductor sheath tube and the inner cavity of the porcelain sleeve are filled with transformer oil, which plays the role of radial insulation. When the voltage exceeds 35 kV, the insulation can be strengthened by putting an insulating tube or cable on the conductor.

Capacitive wire sheath tube

When the capacitor core of the capacitor wire sheath tube is made of adhesive tape, the mechanical strength will be higher, it can be installed at any angle, with good moisture resistance, simple structure and maintenance, and the lower end of the core can be cut into short tails without running sleeve, thus reducing the volume.

Matters needing attention in pipeline layout and arrangement

Arrange the pipeline according to the groove opened in the construction site. When laying pipes in a room with water, it is best to lay electrical pipes on the wall and top. Strong and weak wires are not allowed to walk on the floor of the balcony in the kitchen and bathroom.

Matters needing attention when threading

The sum of the cross-sectional areas of the wires passing through the conduit must be less than 40% of the cross-sectional area inside the conduit. In general, no more than 3 lines are about 16mm, and no more than 4 lines are 20mm.

Installation points of switch socket

The height of switches installed in rows should be consistent, and the height difference should not be greater than 2mm. The spacing between cassettes is 10mm, the height of sockets from the ground is generally at least 300mm, and the switch position is generally 1300mm from the ground.

Layout requirements of through-wall pipes

The layout of wall-penetrating pipes should be smooth and vertical, and try not to bend. If there is a bend, there should be no obvious crease at the corner. The distance between strong and weak current must be greater than or equal to 150mm to prevent the cable signal from being unclear. The distance between gas pipeline and electrical pipeline should not be less than150 mm.
