In our lives, electricity is needed by every family. In places where electricity is available, there will be wires installed, but for safety reasons, wire bushings are generally used, but wire bushings are also classified into many types. when the installation is also need our attention, then what wire casing decoration installation points have that? kind of decoration wiring grommet what it? Xiao Bian below the decoration of the home network come to tell you about it. First, the decoration wire casing installation points 1. According to the groove opened at the construction site, the pipe should be arranged on the wall and the top when the pipe is arranged in the water room. Strong and weak wires are not allowed to walk on the floor of the kitchen and bathroom balcony. 2. The layout of the wall pipe should be smooth and vertical, and try not to bend. If there is a bend, there should be no obvious creases at the turn. The spacing between strong and weak current must be greater than or equal to 150mm to prevent the cable signal from being unclear. The distance between the gas pipe and the electric pipe should not be less than 150mm. 3. The height of the switches installed in rows should be the same, and the height difference should be no more than 2mm. The spacing between the cassettes is 10 mm, the height of the socket from the ground is generally at least 300 mm, and the position of the switch is generally 1300 mm from the ground. 4. When threading, the sum of the cross-sectional areas of the wires worn in a wire tube must be less than 40% of the cross-section of the pipe. Under normal circumstances, 16mm wires should not exceed 3, and 20mm wires should not exceed 4 wires. Second, the decoration wire casing type 1. Composite wire sheathed pipe: oil or gas is used as the insulating medium, generally made of transformer bushing or circuit breaker bushing, which is often used for voltage levels below 35 kV. The inner cavity between the conductor of the composite wire sheathed tube and the porcelain sleeve is filled with transformer oil to provide radial insulation. When the voltage exceeds 35 kV, an insulating tube or a covered cable is sheathed on the conductor to enhance the insulation. The conductor structure of the composite wire sheathed tube has two types: a cable-through type and a guide rod type. The cable-through cable that uses the transformer directly passes through the casing for easy installation. When the working current is greater than 600 amps, it is difficult to install the cable-through structure, and a guide rod structure is generally adopted. 2. Stainless steel sheathed tube: stainless steel sheathed tube, made of 304 stainless steel or 301 stainless steel, used as wire and cable protection tube for wires, cables and automatic instrumentation signals, specifications from 3mm to 150mm. Ultra-small-diameter stainless steel sheathed tube (inner diameter 3mm-25mm) is mainly used for sensing line protection of precision optical scales and industrial sensor line protection. It has good softness, corrosion resistance, high temperature resistance, wear resistance and tensile strength. . 3. Capacitive wire sheath tube: consists of a capacitor core, a porcelain sleeve, a metal attachment and a conductor. When the capacitor core of the capacitor wire sheathed tube is made of adhesive tape, it has high mechanical strength, can be installed at any angle, has good moisture resistance, simple structure and maintenance, can be used without turning the casing, and can be turned into a short tail at the lower end of the heart. , reduce its size. The disadvantage is that at high voltage levels, the material and process requirements are higher, and the air gap is not easily eliminated in the core, resulting in a low partial discharge voltage. In the decoration of the house, the installation of the wires is a troublesome thing. The wire bushings must be installed. Then, the installation points and the types of the wire bushings are decorated. Through the introduction of the above small series, everyone knows about it.
